- 产品名称:PT205 Series可燃气体传感器
- 产品定货号:MR-00197-00
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.
