DG2 series pressure transmitter for refrigeration adopts high-precision and high-stability MEMS chip, with ntegrated structure of 17-4PH stainless steel measuring diaphragm which is made by the world's leading transmitter technology.After intelligent temperature compensation in the whole temperature area, the transmitter has the characteristics of excellent performance, compact structure, small size, fast response speed, convenient installation, wide temperature resistance range, anti-condensation and high media compatibility. Due to its unique structural process characteristics, the self-sealing integrated structure is convenient for product loading, which can prevent the risk of refrigerant leakage during the process, and it has a long service life (the number of full-scale pressure cycles is greater than 10 million).
This kind of pressure transmitter is especially suitable for the refrigeration industry, air compressor matching, and air conditioning production line testing. This product can also be used in refrigerant and steam sterilization equipment.
1. As the sensing experts,Senex is the trusted choice by NASA Space Center and U.S. submarines with technology sourced from USA.
2. With double overload and integrated structure design, the burst pressure is greater than 5 times the full scale.
3. Suitable for refrigeration industry according to wide temperature range, anti-condensation, high media compatibility.
4. The circuit meets intrinsic safety standards and is EMC certified with vibration resistance up to 20g.
5. The USA ANSI Pressure Standards testing organization has passed the test, and the number of full-scale pressure cycles is greater than 10 million times.
6. High measurement accuracy, full temperature compensation, fast response and compact size .
