    產(chǎn)品描述：



    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 – of the detection range of the sensor. Also an LED indicator on the transmitter board provides sensor status and fault condition.
