Refrigeration pressure transmitter LFT2070 is based on ceramic capacitor sensors that are corrosion resistant and with excellent temperature adaptability. The high-performance MCU collects the undergo pressure signal and converts to a standard output signal. These refrigeration pressure transmitters are capable to a wide temperature range from -40°C+120°C. Compact size, easy installation, low cost, and high performance features. It is widely used in the measurement of fluid medium pressure in fire fighting systems, HVACR systems, air compressors, pneumatic devices, industrial automation, automobile cooling systems, and A/C conditioning cooling systems.
