Hvac Refrigerant Pressure Sensor And Transducer

Short Description:

A variety of range parameters can be done, too many models to be on the shelves one by one, if there is any problem can be online consultation or mail communication

This series of pressure transmitters are produced using internationally advanced piezoresistive sensor cores, featuring compact design, ultra-wide working temperature range, and special valve needles for pressure guide ports. They are especially suitable for measuring and controlling fluid pressure in the air conditioning and refrigeration industry.

Applicable Field

The internal thread 7/16UNF mechanical interface is mainly used for pressure measurement of refrigeration equipment such as refrigeration control and air conditioning units.


1.Small structure, convenient installation, overvoltage protection 

2.High precision, good stability, fast response speed, long-term stability

Matters Needing Attention 

1. When wiring, please connect strictly according to the requirements, and it is strictly forbidden to connect wrongly

2. Do not extend hard foreign objects into the pressure chamber of the transmitter. Do not touch the diaphragm with hard objects when using flat membrane diaphragm products, otherwise the product will be completely damaged.

3. Conventional products cannot be used to measure corrosive media, and those with anti-corrosion requirements must be specifically mentioned when ordering.

4. When installing the product, check whether the size of the on-site threaded interface is consistent with the product. When installing or disassembling, you can only use a wrench to screw the hexagon of the product. It is strictly forbidden to screw the shell and lead connector of the transmitter, otherwise the product will be completely damaged.

5. The product is guaranteed for 1 year from the date of delivery. Except for any quality problems caused by man-made reasons and improper use or uncontrollable factors, it will be repaired or replaced free of charge.
