MPM280 OEM Pressure Sensor

Specifications

Product Overview

General MPM280 Piezoresistive Pressure Sensor
The outline, installation dimension and sealing method of the general MPM280 is strongly interchange, it is widely used for measuring pressure which is compatible with stainless steel and Viton;

Assembled MPM280 Piezoresistive Pressure Sensor
Put general MPM280 pressure sensor into the housing with standard or special thread; use face type seal or waterline seal; with flexible construction and serious inspecting and screening; the assembled MPM280 sensor has similar application with general type sensor, it can be used for mounting and production of different pressure instruments;

Welded MPM280 Piezoresistive Pressure Sensor
Put general MPM280 pressure sensor into the housing with standard or special thread; and weld sensor with housing together, no O-ring for sealing. The whole product has flexible construction, it has wider application fields than general pressure sensor, can be used for mounting and production of different pressure instruments;

Flush Diaphragm MPM280 Piezoresistive Pressure Sensor
Flush diaphragm pressure sensor is a full-welded pressure sensor, it has pressure port G1/2 male or M20X1.5 male, sealing by Viton O-ring at the end of thread. The isolated diaphragm is welded in front of thread port, the whole measure range is 0~100kPa…35MPa. It can be used for food, medicine, sanitation fields which the media is easily dirty.

Anti-corrosive MPM280 Piezoresistive Pressure Sensor
The anti-corrosive MPM280 pressure sensor has similar outline, installation dimension and sealing methods as general MPM280 pressure sensor. For construction material, anti-corrosive pressure sensor includes TS type (Tantalum diaphragm+Stainless Steel Housing) and TH type (Tantalum diaphragm+Hastelloy C housing).The sensor is sealed by Viton O-ring. It can be used for strong corrosive media measurement or sea water. The measure range of TS type is 0~100kPa…35MPa. The measure range of TH type is 0~100kPa...2MPa.

Gauge MPM280 Pressure Sensor with Vacuum Measurement
We can use general type, assembled type as well as flash diaphragm type gauge pressure sensor to measure pressure below air pressure, the min. pressure can be around -100kPa.

Titanium anti-corrosive MPM280Ti Piezoresistive Pressure Sensor
The titanium anti-corrosive MPM280Ti pressure sensor has simillar outline, installation dimension and sealing methods as general MPM280 pressure sensor. It uses all titanium material in construction,TC4 housing material and TA1 diaphragm. It can be applied for the pressure measurement of sea water or corrosive media.The measure range is -100kPa~0;0~100kPa...2MPa.
MPM280Ti Piezoresistive Pressure Sensor can be used in wet environment or sea water. Its anti-corrosive performance is far better than stainless steel. MPM280Ti has good anti-corrosive performance for pitting, acid etching, stress corrosion, alkali,chlorine-organism, chloride, nitric acid and vitriol etc.
