HEAT DETECTORS

TMP2 series Heat Detector includes electronic circuit for signal conditioning generated by the transducer. The electrical signal is transformed into an engineered output with different interface solutions. Units are available in Aluminium or Stainless Steel suitable for use in a safe or hazardous area with Rate of Rise or fixed-Point detection.

Fixed temperature detector: The detector is activated exceeding the maximum temperature. The alarm temperature is calibrated as required by customer over a range of -20÷110°C. 

Fixed and rate of rise temperature detector: The alarm is activated exceeding the maximum temperature or for a rapid rate or rise of temperature. Range of calibration is -20÷110°C.
