Air Conditioning P+T Sensor

The P+T Sensor integrated pressure sensor and temperature sensor, provide signal to AC controller.

Feature and benefits

The P+T Sensor provides 2 outputs with temperature and pressure

With ceramic capacity technology, with both high accuracy and long-term stability

Pressure can be customized in the range of 0~4MPa

Temperature curve can be series selected in the range of -40~140℃

Output with 0.5V~4.5V voltage single, with diagnosis function

Protection degree with IP69

Connector and pressure port can be customized

Application

Detect the pressure and temperature of refrigerant media, and transfer to electrical signal to AC controller with condition module. The controller will combinate other signals input, and then control the actuator, to make sure the air temperature falls into comfortable zone for all passengers

Operate
Basic principle

With Ceramic capacitance technology, the pressure change of the medium in pipe will be transferred to capacitance value change, and then be converted into a voltage signal by the conditioning module. The temperature part uses a negative temperature coefficient thermistor, the resistance value decreases vs the temperature increase, and the resistance value can be converted into a voltage signal through the conditioning module.

Connection options

Customized to customer requirement.

Packaging Options
