PRESSURE SENSOR SOFREL LACROIX 20 BAR (4-20 mA) 1/4"

Pressure measurement in drinking water distribution networks

SOFREL CNPr is a piezoresistive pressure sensor for 1/4″ DIN 3852 DIN gas connections, with a high-quality stainless steel membrane. It measures pressure on hydraulic or pneumatic pipes. It connects to a standard thread and delivers a 4-20 mA signal proportional to the pressure in the pipe.

CNPr’s low energy consumption makes it ideal for use with SOFREL data loggers.
