OLCT 80 WirelessWireless Fixed Detector
Wireless field detector and transmitter for detection of oxygen, combustible, toxic and refrigerant gases in remote locations
Now Available in Wireless! The new OLCT 80 model builds on an established design to provide
wireless connectivity in ATEX 1 zones. Providing a range of up to 3km
the OLCT 80 utilises binding technology to ensure that the signal is free
from distortion or interference
Lower Installation Costs Eliminating the need for point-to-point wiring, the operation of the
OLCT80 wireless is as simple as one single field device communicating
with a controller, remote display and alarm station.
Signal Processing you can Rely on The transceivers operate at a universally accepted frequency of 2.4 GHz
and have the capability to transmit signal data from various inputs or
serial MODBUS outputs.
KEYBENEFITS• Suitable design for use in explosive
areas
• On-board display allows
noninvasive one-man calibration
• Reduces installation costs by
eliminating cabling and wiring
• Available with flameproof or
intrinsic-safety sensors
• It can be linked via secure network
to monitor large remote areas
The OLCT 80 Wireless is suited for transmitting signal data in a wide range of industrial applications
