AZIC500-502 Digital Display Pressure Switch is produced by Chinese top famous factory: Anhui Ziyi Instrument Co., Ltd.
【Product Description】
AZIC500-502 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.
