        Microprocessor based modular design 
Industry standard 4-20mA output 
LED Status Indicator 
12-24 VDC Power input 
Reverse polarity protection 
Class I, Div 1, Suitable for use in Hazardous Location 
Simple Calibration 
Description
Model PT205 sensor is designed to detect combustible hydrocarbons vapors in air and provides an analog output signal. PT205 uses catalytic beads sensor to detect combustible vapors in % LEL. 
The complete sensor consists of a stainless steel sensor head assembly, a user connection board and a transmitter board assembly. All of the sensor electronics are enclosed in an explosion proof instrument box. The unit’s modular design allows easy maintenance, troubleshooting and high reliability. The low power microprocessor based sensor transmitter provides a 4-20mA analog signal proportional to 0 – 100% of the detection range of the sensor. Also an LED indicator on the transmitter board provides sensor status and fault condition.
