LED digital water pressure switch

Description of LED digital water pressure switch

UPS1 intelligent pressure switch is newly developed by UTOP, and it combines the functions of pressure measurement, display and control together. UPS1 adopts the advanced MCU and DSP IC, equipped with high reliability of power management module, and also integrated high quality piezoresistive pressure sensor (UPX19 model). After our R&D engineer’s careful design and calibration, UPS1 realizes the feature like high speed response and good electromagnetic compatibility.

UPS1 intelligent pressure switch realizes the visual processing for process pressure and switch contact state through its switch output, analogue output and displaying screen. This product can be provided with various output configuration to meet different application. UPS1 has the functions of delay setting, manual reset(clear zero), as well as peak value display etc. The display screen can rotate 180°, and switch body can rotate 340°. UPS1 supports serial port 232 level communication, it adopts MODBUS-RTU PROTOCOL.

UPS1 is widely used for industrial site pressure control in pump, hydraulic and pneumatic equipments.
