OLC 100 and OLCT 100 ranges
The OLC 100 range is reserved for the detection of explosive vapor by using a
Wheatstone bridge sensor.
The OLCT 100 range of detectors is provided with an amplifier producing a 2 or 3
wire 4-20 mA analog output. These are transmitter detectors and, therefore, the
letter "T".
(1) Requires the use of a Zener barrier
(2) Sensor can be remote up to 5, 10, or 15 meters using a high temperature cable
(3) mV bridge output, 3 wires
EC : Electrochemical sensor
SC : Semi-conductor sensor.
LEL : Catalytic bead
AP : Poison resistant
