Honeywell TP974A2000/U

The Pneumatic Room Sensor is utilized in conjunction with controllers to enable proportional control of pneumatic valve or damper actuators in HVAC systems. This model is specifically tailored for temperature sensing, featuring a bimetal sensor element.

With a direct acting product action, the sensor is capable of operating within a temperature range of 10 to 38 °C. Its physical dimensions include an overall width of 2 inches (51 mm), height of 3.25 inches (83 mm), and depth of 1.625 inches (41 mm). The sensor is wall-mounted and is equipped with a 1/2 inch NPSC straight pipe thread for connection to a well.

Operating under a minimum supply pressure of 16 psi (110 kPa) and a maximum of 124 kPa, the sensor maintains output pressures ranging from 21 kPa to a maximum of 103 kPa. It supports airflow usage of 0.019 cfm (9 ml/s), ensuring reliable performance in various ambient conditions.
