1 and 3R NEMA Rated, 20 to 40 psi, Electromechanical Pressure and Level Switch MPN:9013FRG22J23

1 and 3R NEMA Rated, 20 to 40 psi, Electromechanical Pressure and Level Switch is a versatile monitoring solution for a broad range of industries involved in controlling liquid or gas processes. With precision accuracy across temperature variations between -10F to +48.9C (-43.9C to 123.2C), this pressure switch offers reliable detection of level fluctuations, alerting users to either empty, high-level, or continuous state conditions in closed systems like fuel tanks, coolants, water treatment, HVAC/R components, etc. Its compact and NEMA 1 enclosure guards against accidental contact while minimizing space requirements, making it ideal for both indoor and outdoor applications alike; its low actuation pressure drop allows efficient functionality even during minute-level changes in the process being monitored; finally, this cost-effective device is easily installed and available with either an easy-to-read pointer or a 4-20 mA analog output, offering users tailored options depending on their preferences, ensuring maximum satisfaction when monitoring key liquid & gas pressures at all times.
