1. OLCT 80 Wireless
Wireless Fixed Detector
Wireless field detector and transmitter for
detection of oxygen, combustible, toxic and
refrigerant gases in remote locations
Now Available in Wireless!
KEYBENEFITS
•
Suitable design for use in explosive
areas
•
Reduces installation costs by
eliminating cabling and wiring
•
Available with flameproof or
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
intrinsic-safety sensors
•
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
On-board display allows
noninvasive one-man calibration
•
The new OLCT 80 model builds on an established design to provide
It can be linked via secure network
to monitor large remote areas
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
