HM23 Special Pressure Transducer for Air Conditioner, Refrigerating and Compressor
Description
HM23 series of pressure transducer is specially designed for accurate measurement of pressure in air conditioner, refrigerating and compressor as well as hydraulic system, including multiple refrigerants, mixture of refrigerant and lubricant, oil, water, gas etc. It is designed and manufactured in ODM way. Our design team may improve or re-design to meet the requirements of the individual customer at the customer’s requests.
Features of Product
☆ Designed with a built - in stabilizer, may use any unadjusted power supply of energization under a certain range.
☆ Designed with Solid structure and effective moisture – proof protection to ensure that the sensor may be installed and operated in very bad environment.
☆ Designed with wide – range temperature compensation to effectively reduce the influence of ambient temperature and the temperature of medium measured to the transducer.
☆ Excellent long-term stability
☆ Designed with Electromagnetic compatibility (EMC) protection to meet the relevant requirements of IEC.
