The Model 178A Series are low range differential pressure transducers and transmitters in HVAC building automation, high accuracy pharmaceutical and health care facilities. The patented variable capacitance pressure sensor is constructed by stainless steel and glass, no glue or other organics. That provides excellent performance, corrosion resistance and long-term stability, the Model 161 delivers reliable measurements below 0.05 inches of water.
