The latest innovation to our range of switches features a robust high quality housing with 1 or 2 sealed SPDT microswitches and has been designed for use in environments where explosive gases can be present (e.g. gas fields, oil rigs & chemical plants etc).
One of the benefits of the Perseus range is the separation of the flameproof and adjustment chambers allowing adjustment of the set point with power on and the switch in operation.

INDUSTRIAL SWITCHES
The Perseus pressure, vacuum, differential pressure, temperature, and level switches are designed for use in environments where explosive gases can be present (e.g. Gas fields, Oil rigs and Chemical plants etc.) and have been ATEX and IECEx certified as detailed overleaf (SIL2 - IEC61508 proven reliability).
These switches are manufactured from a high quality casting which offers robust construction and protection to IP67 for use within heavily polluted industrial environments. A special feature of the instruments is the separation of the flameproof and adjustment compartments allowing for safe on-site adjustment of the set point with power on and the switch in operation.
Perseus Exd switches must be installed in accordance with BS EN 60079-14
INTRODUCTION
The design features a simple form of adjustment against a calibrated scale. This enables a user to order switches set at a predetermined point or stock a mid range setting and adjust switches to suit the particular application. The set point can be safely adjusted with the switch electrically live. Adjustment is made by removing the access cover and rotating the set point adjuster using the supplied tommy bar stowed to the right of the scale plate. The setting is read from the centre of the set point adjuster against the calibrated scale. Rotation to the left will increase the set point and to the right decrease it.
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.

One of the benefits of the Perseus range is the separation of the flameproof and adjustment chambers allowing adjustment of the set point with power on and the switch in operation.

INDUSTRIAL SWITCHES
The Perseus pressure, vacuum, differential pressure, temperature, and level switches are designed for use in environments where explosive gases can be present (e.g. Gas fields, Oil rigs and Chemical plants etc.) and have been ATEX and IECEx certified as detailed overleaf (SIL2 - IEC61508 proven reliability).
These switches are manufactured from a high quality casting which offers robust construction and protection to IP67 for use within heavily polluted industrial environments. A special feature of the instruments is the separation of the flameproof and adjustment compartments allowing for safe on-site adjustment of the set point with power on and the switch in operation.
Perseus Exd switches must be installed in accordance with BS EN 60079-14
INTRODUCTION
The design features a simple form of adjustment against a calibrated scale. This enables a user to order switches set at a predetermined point or stock a mid range setting and adjust switches to suit the particular application. The set point can be safely adjusted with the switch electrically live. Adjustment is made by removing the access cover and rotating the set point adjuster using the supplied tommy bar stowed to the right of the scale plate. The setting is read from the centre of the set point adjuster against the calibrated scale. Rotation to the left will increase the set point and to the right decrease it.
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.

INDUSTRIAL SWITCHES
The Perseus pressure, vacuum, differential pressure, temperature, and level switches are designed for use in environments where explosive gases can be present (e.g. Gas fields, Oil rigs and Chemical plants etc.) and have been ATEX and IECEx certified as detailed overleaf (SIL2 - IEC61508 proven reliability).
These switches are manufactured from a high quality casting which offers robust construction and protection to IP67 for use within heavily polluted industrial environments. A special feature of the instruments is the separation of the flameproof and adjustment compartments allowing for safe on-site adjustment of the set point with power on and the switch in operation.
Perseus Exd switches must be installed in accordance with BS EN 60079-14
INTRODUCTION
The design features a simple form of adjustment against a calibrated scale. This enables a user to order switches set at a predetermined point or stock a mid range setting and adjust switches to suit the particular application. The set point can be safely adjusted with the switch electrically live. Adjustment is made by removing the access cover and rotating the set point adjuster using the supplied tommy bar stowed to the right of the scale plate. The setting is read from the centre of the set point adjuster against the calibrated scale. Rotation to the left will increase the set point and to the right decrease it.

Switching is effected in this unit through transforming, by means of a eccentric cam at fulcrum, the vertical motion of the flow with level change to the considerably reduced movement of a horizontal switch plunger which is arranged to operate a one or two SPDT/SPCO microswitches.
This type of level switch can be used on tanks under pressure or vacuum, being suitable for pressures up to 3.5 Bar (only with spherical float) and liquid temperatures up to 100°C. It is suitable for low temperature operation but will not operate if the liquid is frozen.
The device can be mounted through a 27mm hole drilled in the side of the tank with joint washer and back nut pro-vided. (access inside the tank will be required to attach the float. Alternatively it can be provided with a flange and cylindrical float which will allow for the insertion of the switch complete with float.
