Product Introduction

Instrument Overview

Indicating positive pressure, negative pressure and differential pressure ,Product accuracy guarantee in 1 percentage 

   The 2000 series  magnehelic micro differential pressure gauge have 81 span ammeters,the precision of which is 2%。It adopts a wear-free movement with simple and reliable structure, which can quickly and sensitively indicate the
 micro positive pressure, negative pressure and differential pressure of gas. It also has the functions of shockproof and overvoltage protection。The price of the Magnehelic micro differential pressure gauge is economical and reasonable,and the use is convenient. The problems of liquid evaporation, freezing and horizontal correction of the liquid differential pressure gauge in measurement are avoided。The 2000 series magnehelic micro differential pressure gauge is widely used to monitor the static pressure at the outlet of fan, filter resistance, wind speed, ventilation status, differential pressure on both sides of orifice plate, bubble level measurement system, liquid level, gas and air mixing control ,ratio, blood pressure and respiratory pressure in medical equipment and devices.

Note: it can be used for hydrogen, but Buna-N nitrile rubber diaphragm must be selected when ordering, and the working pressure is 35psi.

Product features

The bezel can be used for embedded panel installation.

Transparent dial has high strength and resistance to damage. There is no deformation when reading the pointer and scale.

The precision lithographic scale can read accurately.

The red pointer at the end is very eye-catching. It is made of heat-treated aluminum tube and fixed on the spiral shaft。

The pointer stop is made of molded rubber to avoid damage in case of excessive pointer travel。

Cross arm fittings assemble the screw shaft, screw bearing and pointer shaft together。

The gem bearing adopts shockproof installation; It can make the helical shaft move without friction. Use high viscosity silicone oil for motion damping。

The zero adjustment screw can adjust the zero point without removing the dial. O-ring is adopted, with good sealing performance。

The spiral shaft is made of high permeability alloy. With gem bearing, it can move freely. It is used to rotate the pointer to indicate the scale.

Samarium cobalt permanent magnet block is installed at the other end of the range spring to rotate the spiral shaft with magnetic force。

The range calibration reed is spring steel. The small stroke makes the instrument have good repeatability and long service life. It is linked with the pressurized diaphragm to adjust its effective length to calibrate the range.

The silicone diaphragm and O-ring are integrally molded together and installed between the front plate and the rear plate. It is tightly fixed and sealed. Diaphragm displacement is limited to protect against possible damage from 
overpressure。

The precision manufactured cast aluminum shell can withstand 168 hour salt spray corrosion test. Dark grey baked paint surface. All enclosures are standard dimensions ,which can be surface mounted and embedded。

The overpressure plug is made of silica gel and the overpressure rating is 15 psig. It will eject at about 25 psig。

The O-ring is used between the gauge cover and the housing to ensure that the pressure is sealed inside。
