Fireye® TS348-4 1037626

The PS348 and TS348 Series of pressure and temperature sensors are designed for use with the E340 boiler room control system. The pressure sensors (P/N PS348-x) utilize a solid state pressure transducer to indicate steam pressure, oil pressure and gas pressure. The temperature sensors (P/N TS348-x) utilize a platinum, positive temperature coefficient sensing element to provide indication of water temperature, oil temperature, stack temperature, boiler water temperature of a steam boiler and outdoor air temperature. Both pressure and temperature sensors are enclosed in a rugged 16 ga drawn steel housing. The pressure sensors have a maximum overpressure specification of 200% Full Scale Output (800%) Burst) and are equipped with a 1/4s NPT fitting. The immersion style temperature sensors have a 1/2s NPT mounting for the 2s 4s and 8s thermowell probe. The pressure sensors provide a 1-5 VDC control signal to the E340 Control and the temperature sensors provide a resistive input signal to the E340. No setting or calibration is required for either type of sensor. The output signal at the pressure sensors is 1 to 5 VDC over its stated range. A constant 1 mA dc current is applied separately to each temperature sensor to maintain accuracy and reduce variability. The E340 performs a continuous safety check on the operation of all pressure and temperature sensors to insure their safe and proper operation (e.g. detect stuck sensor, open wiring, etc.).
