Air Conditioning Pressure Sensor

The pressure sensor detects the pressure signal and provides it to the air conditioning controller.

Feature and benefits

The sensor provides analog signal or digital signal

With ceramic capacity technology, with both high accuracy and long-term stability. Ceramic has excellent compatibility with almost all automotive pressure media

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

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 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

According to the change of the medium pressure in the induction pipe, the air conditioning pressure sensor will lead to the deformation of the ceramic strain film and change the capacitance value, which will be amplified by the conditioning circuit and converted into a voltage signal.

Connection options

Customized to customer choice of connection system

Packaging Options

Custom packaging can be provided to meet any need, please contact KESENS Engineering for details
