Brief description of piezoresistive pressure sensor
Time:2018-09-15
Piezoresistive pressure sensor is a kind of pressure sensor utilize piezoresistive effort, transform the resistance change to electronic signal, typically mV, V(0-10V, 0-5V) or mA(4-20mA). It use a high stable silicon chip as the sensing element, which is protect by stainless steel 316L diaphragm with silicone oil filled. Various of pressure connections and electrical connections are available to meet the different requirement.
Sendo Sensor is one of the best china manufacturers work at piezoresistive pressure sensor. The following items are the relative products of the pressure sensor, you can quickly find the sensors through the list.
Typical 1: SS305 Series piezoresistive pressure sensor
SS305 series high overload pressure sensor is a portfolio of highly configurable pressure sensors that use piezoresistive sensing technology with a special signal conditioning circuit in a stainless steel housing, meets the high burst protection demands andis suitable for the use in all types of severe industrial applications.
SS305 series is fully calibrated and compensated for offset, sensitivity, temperature effects and non-linearity, provides a Total Error Band of ±0.5% over the operating temperature range of 0 °C to 70 °C [14 °F to 176 °F].
SS305 series is a precise pressure measurement solution that optimizes system performance at a competitive cost, numerous standard or custom connectors, ports, pressure ranges and types, and output options.
Typical 2: SS100 series Piezoresistive Pressure Transducer
The SS100 series piezoresistive pressure transducers cover all pressure ranges from 100 mbar to 1000 bar Absolute, gauge, sealed gauge pressure. It has standard size Φ 1 9 × 15 mm, stainless steel 316L housing and Stainless steel 316L diaphragm structure, Wider temperature compensation range, and offers Constant current or voltage supply.
The transducer has isolated construction and able to test various media. A high-sensitivity piezoresistive silicon chip is used for pressure sensing make the transducer high accuracy and reliability. The chip is protected against ambient influencesby a stainless steel housing sealed with a concentrically corrugated diaphragm. The housing is filled with silicone oil so as to ensure the transfer of the pressure from the diaphragm to the sensing component.
Several millions of these pressure transducers are in use world-wide in a variety of different applications. Main fields of application are: Level technology, pneumatics, hydraulics, avionics.
