PENN® A99 series sensors are equipped with a calibrated, highly sensitive thermistor with a positive temperature coefficient.
These sensors have the advantages of PT-100 sensors as well as PTC thermistors. To ensure the highest possible sensor quality, each thermistor is calibrated according to a standard characteristic. Moreover, replacing the sensor is extremely simple and does not require recalibration.
Sensors in this series are designed to work with the 27 NOVA system, MR / MS, R78, A255, DX-9100, XP-9102, XPA-4 × 1, XPA-8 × 1 electronic controllers and the Facility Explorer (FX) platform controllers by Johnson Controls.
