【Product Description】
FST500-502 Digital Display Pressure Switch provides continuous pressure monitoring, and the user can easily set the switching point and differential point without the need for booster equipment. The switch load capacity of the pressure switch ranges from several uA to 500mA, and simultaneously converts the collected pressure signal into a standard current signal output. The product display head and joints can be rotated flexibly to ensure that the product can work smoothly in some difficult-to-install occasions.
【Product Features】
●Good pressure resistance and strong overpressure performance
●A variety of switch quantities and transmission signal outputs are optional
●Equipped with four-digit LED digital field display function
●Rotatable head, more convenient to view data
【Application Range】
●Applicable to pump control, tank monitoring, liquid level control, filter blockage, monitoring, leakage monitoring
●Industrial process detection and control
●Building automation, constant pressure water supply
●Petrochemical, environmental protection, water conservancy, light industry, machinery, metallurgy
