Differential pressure switch with gauge

Product Overview

Description

Applications and features

Adopt high-precision MEMS sensor and digital technology to detect positive pressure, negative pressure or differential pressure

It can be widely used to measure the pressure of fans and blowers, filter resistance, wind speed, pressure drop caused by furnace ventilation and orifice plate, liquid level of foaming system and pressure of supercharger or hydraulic system

It can be used to monitor blood and respiratory pressure on medical equipment

Applicable to embedded installation, plane installation and other installation methods

A variety of ranges, output modes and units are optional

No moving parts, anti vibration

At the same time, it has super large and super bright nixie tube display and optional arc-shaped LED indication of analog mechanical meter

Two groups of relay output or alarm can be selected, and LED indication is provided at the same time
