Pem-Tech, Inc. Toxic & Oxygen Sensor PT395

Description
Features Microprocessor based modular design Electrochemical Sensor Technology Industry standard 4-20mA output Field adjustable Alarm level Single point Non-Intrusive calibration Bright 3 digit LED display Displays gas concentration in ppm, calibration prompts and sensor fault codes Suitable for use in Hazardous Location Description Model PT395 Series is a microprocessor-based sensor for the detection of toxic gas in ambient air. The unit features easy one-man calibration initiated by simply activating a magnetic switch and applying the gas. 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 unit provides a fully programmable alarm relay and a linear 4-20mA signal proportional to 0 to 100% of the detection range of the sensor. The sensor transmitter board includes a three (3) digit LED display for continuous indication of the gas concentration. The calibration mode, alarm and fault status of the sensor are also indicated on the digital display. In the normal operating mode the digital display and 4-20mA reading is proportional to the gas concentration detected by the sensor. In the calibration mode the digital display indicates the calibration status, alarm relay output is inhibited and analog signal output is set to 2 mA to avoid any false alarm by the control monitor. In the sensor fault mode the transmitter drops the output signal to < 1 mA.
