Brief Description of OEM Pressure Sensor and Applications

We develop and produce OEM pressure sensors using piezoresistive technology for high standards in our own plant. The piezoresistive diffused silicon pressure sensor uses a high-precision semiconductor resistance strain gauge to form a Wheatstone bridge as a force-electric conversion measurement circuit. It has high measurement accuracy, low power consumption, and extremely low cost, with our many years of production experience our products have the highest measuring accuracy and stability, it is usually used by manufacturers of pressure transmitters and pressure measuring systems.

SS301 series liquid pressure sensor take advantage of piezoresistive technology, and are fully steel media isolating with stainless steel and no internal elastomer seals. This design often makes them resistant to harsh, aggressive media and challenging environments. The sensor is mounted in a stainless steel package with a small volume of oil between the diaphragm and sensor. The pressure housing uses the oil to transmit the pressure from the diaphragm to the sensor.

SS102 series piezoresistive sensing capsule cover the pressure ranges from 100 mbar to 100bar. It use a high-stability silicon chip which is protected by 316L stainless steel diaphragm and silicone oil. The applied pressure acts on stainless steel diaphragm, then pass to the silicon chip through silicone oil. Typically application in level measurement, industrial process control, gas and liquid pressure measurement. Standard size Φ19 × 10mm, Stainless steel 316 diaphragm and housing.
SS207 series water pressure sensor is the one of the most mature product in Sendo, it is OEM tested, with high accuracy, long term stability, good repeatability, has been wildly used in automotive oil system, automotive AC system, automotive brake system and other car security system, available with range 15psi, 30psi, 50psi, 75psi, 100psi, 150psi.
SS307 series ceramic diaphragm pressure transmitter give out a current signal 4 to 20mA or voltage signal 0 to 10V directly proportional to the pressure value present on the system to which they are connected, the housing is made from stainless steel with a choice of internal O ring seals to select to ensure the product is suitable for a wide range of applications.
SS302 series vacuum pressure sensor is the basic type in Sendo Sensor, also it is the most widely used one, work following the piezoresistive principle, there are two potentiometers inside the housing so it is zero and span adjustable. It uses high stable and reliable pressure transducer and special circuit board to produce transmitter, and performance is good and reliable.
SS103 series media isolated pressure sensor is the most economic version for pressure ranges from 350 mbar to 100 bar. They have a height of only 5 mm without compromising quality and performance. This piezoresistive measuring cell are made of stainless steel 316L, the standard version is supplied with connecting pins.

SS205 series AC pressure sensor designed by piezoresistive technology with all stainless steel structure, no O-ring is used for sealing inside, offer measuring ranges from 0 15psi to 3000psi absolute prssure and gauge pressure, typical pressure connection is 7/16-20UNF screw.

SS115 series flush pressure transducer designed by piezoresistive sensor technology, the silicon chip is protected by 316L stainless steel and silicone oil filled in the isolated housing, meet “clean in place” (CIP) and “sterilize in place” (SIP) maintenance procedures demand, typically for use in food, process and industrial applications where the media is either viscous, or is otherwise liable to block the port of a conventional pressure transducer with a recessed diaphragm or pressure port.
SS305 series hydraulic 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 and is suitable for the use in all types of severe industrial applications.
SS402 series flush pressure transmitter utilize piezoresistive technology with a high performance silicon chip inside, the applied pressure acts on stainless steel 316L diaphragm, then pass to the silicon chip through silicon oil, available pressure ranges spanning from 5 psig up to 5800 psig. Typically, applications are designed for use in food, process, and industrial applications where the media is either viscous or is otherwise liable to block the port of a conventional pressure transducer with a recessed diaphragm or pressure port.
SS108 series isolated piezoresistive capsule is with isolated construction and precise compensation. It uses high stable silicon die, housing with outer diameter Ф15mm 316L stainless steel housing. They have been developed especially for the measurement of high pressures such as 100bar, 600bar, covered a wide pressure range from 1 Mpa to 100 Mpa(10 bar to 1000 bar), gauge, sealed gauge and absolute pressure is optional.

PS100 series piezoresistive ceramic pressure sensor chip is a dry-type ceramic piezoresistive sensor chip by special technology. Ceramic is a recognized material of high elasticity, corrosion & abrasion resistance, strong shock and vibrant resistance. The thermal stability can make its operating temperature up to -40 to 125°C, It achieves high accuracy, high stability. Electrical insulation 2kV, strong output signal, excellent long-term stability.
