GUARDIAN INDUSTRIAL & ATEX SWITCHES
The Guardian pressure, differential pressure, temperature, level and flow switches are a part of our extensive range of specialist process sensors. They utilise the expertise gained from over 50 years experience of designing and manufacturing control devices for industrial, marine and hazardous area applications.
These switches are constructed with either a robust aluminium or stainless steel enclosure. The aluminium casting is black anodised and supplied with 316 stainless steel covers. The stainless steel case is a natural finish. Covers are gasketted and sealed to achieve an environmental seal to IP66 & IP67 standards. The internals utilise a unique mechanism designed by the engineers at PYROPRESS to produce a wide range, low switching differential and excellent repeatability. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.
INTRODUCTION
The design features a simple form of calibration adjustment against a scale plate. This allows users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small Tommy bar or Allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.
Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintenance instructions supplied with each switch.
CALIBRATION
Our products are designed to work in demanding and hazardous environments which require fast and cost effective solutions in instrumentation
and control. Pyropress control sensors provide safe and
reliable electrical switching of alarm or control circuits in response to changes in temperature, pressure, differential
pressure,vacuum, fluid, flow and level conditions.
ABOUTPYROPRESS QUALITY
To support the design of state of the art products the company has invested heavily in the latest CNC technology.
We are able to produce our own components to a high degree of aaccuracy assuring a reliable and
consistent quality product.

GUARDIAN INDUSTRIAL & ATEX SWITCHES
The Guardian pressure, differential pressure, temperature, level and flow switches are a part of our extensive range of specialist process sensors. They utilise the expertise gained from over 50 years experience of designing and manufacturing control devices for industrial, marine and hazardous area applications.
These switches are constructed with either a robust aluminium or stainless steel enclosure. The aluminium casting is black anodised and supplied with 316 stainless steel covers. The stainless steel case is a natural finish. Covers are gasketted and sealed to achieve an environmental seal to IP66 & IP67 standards. The internals utilise a unique mechanism designed by the engineers at PYROPRESS to produce a wide range, low switching differential and excellent repeatability. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.
INTRODUCTION
The design features a simple form of calibration adjustment against a scale plate. This allows users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small Tommy bar or Allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.
Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintenance instructions supplied with each switch.
CALIBRATION
Our products are designed to work in demanding and hazardous environments which require fast and cost effective solutions in instrumentation
and control. Pyropress control sensors provide safe and
reliable electrical switching of alarm or control circuits in response to changes in temperature, pressure, differential
pressure,vacuum, fluid, flow and level conditions.
ABOUTPYROPRESS QUALITY
To support the design of state of the art products the company has invested heavily in the latest CNC technology.
We are able to produce our own components to a high degree of aaccuracy assuring a reliable and
consistent quality product.

EXAMPLE. Dual microswitches - if switch 1 is set at 10 Bar on a 4 - 12 Bar range switch 2 can be set at the same pressure or between 10.2 and 12.0 Bar with standard adjuster and between 10.7 and 14.5 bar with secondary adjuster. With the second-ary adjuster fitted microswitches cannot be set together.Note: 1) Lowest set point is always switch 1 on dual set point switches. 2) Adjustable deadband mechanism actuates on falling settings, therefore reset on rising pressure.

GUARDIAN INDUSTRIAL & ATEX SWITCHES
The Guardian pressure, differential pressure, temperature, level and flow switches are a part of our extensive range of specialist process sensors. They utilise the expertise gained from over 50 years experience of designing and manufacturing control devices for industrial, marine and hazardous area applications.
These switches are constructed with either a robust aluminium or stainless steel enclosure. The aluminium casting is black anodised and supplied with 316 stainless steel covers. The stainless steel case is a natural finish. Covers are gasketted and sealed to achieve an environmental seal to IP66 & IP67 standards. The internals utilise a unique mechanism designed by the engineers at PYROPRESS to produce a wide range, low switching differential and excellent repeatability. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.
INTRODUCTION
The design features a simple form of calibration adjustment against a scale plate. This allows users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small Tommy bar or Allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.
Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintenance instructions supplied with each switch.

GUARDIAN INDUSTRIAL & ATEX SWITCHES
The Guardian pressure, differential pressure, temperature, level and flow switches are a part of our extensive range of specialist process sensors. They utilise the expertise gained from over 50 years experience of designing and manufacturing control devices for industrial, marine and hazardous area applications.
These switches are constructed with either a robust aluminium or stainless steel enclosure. The aluminium casting is black anodised and supplied with 316 stainless steel covers. The stainless steel case is a natural finish. Covers are gasketted and sealed to achieve an environmental seal to IP66 & IP67 standards. The internals utilise a unique mechanism designed by the engineers at PYROPRESS to produce a wide range, low switching differential and excellent repeatability. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.
INTRODUCTION
The design features a simple form of calibration adjustment against a scale plate. This allows users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small Tommy bar or Allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.
Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintenance instructions supplied with each switch.
CALIBRATION
Our products are designed to work in demanding and hazardous environments which require fast and cost effective solutions in instrumentation
and control. Pyropress control sensors provide safe and
reliable electrical switching of alarm or control circuits in response to changes in temperature, pressure, differential
pressure,vacuum, fluid, flow and level conditions.
ABOUTPYROPRESS QUALITY
To support the design of state of the art products the company has invested heavily in the latest CNC technology.
We are able to produce our own components to a high degree of aaccuracy assuring a reliable and
consistent quality product.

GUARDIAN HORIZONTAL MOUNTING
These liquid level switches are designed to give indication of high or low level alarms in tanks or vessels. They are fitted with a round or cylindrical float, the movement of which operates an SPCO microswitch via an offset pivot and push rod. A second microswitch can be fitted to give an additional signal.
The switch can be installed either via a 27mm clearance hole, utilising the joint washer and back nut supplied, and the float re-attached to the rod. Where there is no access to the tank interior, the cylindrical float with 2”/50mm flange version enables installation without removing and re-attaching the float.

FIG. 17 TYPE F1000 GUARDIAN FLOW SWITCH
GUARDIAN INDUSTRIAL & ATEX SWITCHES
The Guardian pressure, differential pressure, temperature, level and flow switches are a part of our extensive range of specialist process sensors. They utilise the expertise gained from over 50 years experience of designing and manufacturing control devices for industrial, marine and hazardous area applications.
These switches are constructed with either a robust aluminium or stainless steel enclosure. The aluminium casting is black anodised and supplied with 316 stainless steel covers. The stainless steel case is a natural finish. Covers are gasketted and sealed to achieve an environmental seal to IP66 & IP67 standards. The internals utilise a unique mechanism designed by the engineers at PYROPRESS to produce a wide range, low switching differential and excellent repeatability. This combined with a variety of microswitches, mountings and sensor options has produced a switch range suitable for all weatherproof and intrinsically safe applications.
INTRODUCTION
The design features a simple form of calibration adjustment against a scale plate. This allows users to either order units with a specific setting, or stock a mid range setting and then calibrate to suit the application. Calibration is performed on the opposite side of the switch to the electrical connections, and can be set safely with the switch supply live. On removal of the adjustment cover a small grub screw can be loosened allowing the adjusting ring to be turned with a small Tommy bar or Allen key. The setting is read from the centre of the red indicating ring against the calibrated scale plate.
Calibration procedures for dual microswitches and adjustable switching differential switches are detailed on the operating and maintenance instructions supplied with each switch.
CALIBRATION
