Introduction

General MPM280 Piezoresistive Pressure Sensor


The outline, installation dimension and sealing method of General MPM280 pressure sensor is strongly interchangeable, it is widely used for measuring pressure which is compatible with stainless steel and Viton;


Flush Diaphragm MPM280 Piezoresistive Pressure Sensor


Flush diaphragm pressure sensor is a pressure sensing element through male thread and clamp connection. It has pressure port G1/2 male, R1/2 male,M20x1.5 male and DN25 clamp, sealed by Viton or silicon O-ring. The isolated diaphragm is welded in front of thread port, the range is 0~100kPa…35MPa(thread connection) and 0~100kPa…3.5MPa(clamp connection). It can be used to detect the pressure of food, medicine, sanitation fields and the occasion in which the measured media is easily dirty.


Anti-corrosive MPM280 Piezoresistive Pressure Sensor


MPM280TH pressure sensor has similar outline, installation dimension and sealing methods as general MPM280 pressure sensor. For construction material, the isolated diagram uses tantalum material and housing uses Hastelloy C material. The sensor is sealed by Viton O-ring. It can be used to measure strongly corrosive media. The pressure range is -100kPa~0kpa;0~100kPa…35MPa.

MPM280TS pressure sensor has similar outline, installation dimension and sealing methods as general MPM280 pressure sensor. For construction material, the isolated diagram uses tantalum material and housing uses stainless steel 316L material. The sensor is sealed by Viton O-ring. It can be used to measure strongly corrosive media. The pressure range is -100kPa~0kpa;0~100kPa…35MPa.


MPM280HH pressure sensor has similar outline, installation dimension and sealing methods as general MPM280 pressure sensor. It uses all Hastelloy C material in construction,The sensor is sealed by Viton O-ring. It can be used to measure strongly corrosive media. The pressure range is -100kPa~0kpa; 0kPa~100kPa…35MPa.

MPM280Ti pressure sensor has similar 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 used to measure sea water or corrosive media. The pressure range is -100kPa~0kpa; 0kpa~100kPa…70MPa.

MPM 280Ti 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, chloride, chlorine-organism, nitric acid and vitriol etc.

Notes

1.We suggest you to use Floating construction when you install the sensor to prevent affecting sensor stability;

2.Please pay attention to protect sensor isolated diaphragm and ceramic compensated board, to avoid damaging sensor or affecting the performance;

3.Temperature resistant range of standard Viton O-ring of sensor is -20℃ ~ 250℃. When working temperature is lower than -20℃, or sensor is applied in critical environment, please contact us.
