The AC-1 pressure transmitter is specifically designed for pressure monitoring in refrigeration and commercial HVAC applications. The one-piece brass case and ceramic sensor element provides durability and resistance to the most commonly used refrigerants. The transmitter features a compact, space-saving design for easy installation when mounting space is limited. The pressure range, available starting from 30 inch Hg vacuum (-1 bar) is 100-850 psi (7-60 bar). The transmitter provides a linear, amplified voltage or milliamp signal output with short circuit, reverse polarity, and overvoltage protection. The ceramic thick film sensor has no measurable hysteresis error.
