Industrial pressure transmitters or sensors application in the various industrial field, such as pump station, compressor, frequency converter, building automation, electric power, papermaking industry, water pressure measurement and so many others. The working environment of the industry is very different from one to another, so this need the pressure sensor should be more rugged to meet the hard condition, like high temperature, shock and vibration. The industrial pressure sensors are designed for this application. They have a rugged stainless steel housing with 316L stainless steel diaphragm or anti-corrosive ceramic transducer, integrated with a digital amplifier PCB or zero and span adjustable analog amplifier PCB. 4~20mA, 0~10V, 1~10V, 0.5~4.5V various output signal is optional.
Flush pressure sensors or transducers 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. There are two kinds of technology used in sendo sensor, one is piezoresistive(for general application such as bear, milk, vapour) and another is stainless steel strain gauge(for slurry, cement, crude oil). Both of them are S.S.316L flush diaphragm pressure connections, such as G1/2”, 1/2”BSP... Isolated structure, stainless steel welding housing, meet “clean in place” (CIP) and “sterilize in place” (SIP) maintenance procedures design. Various output signal such as: 0~10V, 1~10V, 0.5V~4.5V and 4~20mA output signal is optional.
piezoresistive ceramic pressure sensors have the great performance of corrosion and abrasion resistance, standard 18mm diameter can be easily assembled or encapsulated into a stainless steel housing. Ceramic pressure transmitters are engineered to meet many industrial, commercial, and OEM pressure measurement applications. The ceramic sensing element with Viton seals can be used to sense any compatible media. With a robust design resistant to vibration, shock. Ceramic pressure sensors provides a low cost price with the pressure sensing ranges from 2bar to 400bar, give out a current signal 4-20mA or a voltage signal 0-10V, 0.5-4.5V directly proportional to the pressure value present on the system to which they are connected.
submersible pressure sensors are used to measure level and depth for water and also for harsh harsh liquids and chemicals. The stainless steel submersible pressure sensor contains a piezo-resistive sensor that outputs a signal proportional to the hydrostatic pressure on the diaphragm, the signal is compared to the atmospheric pressure via the vent tube and compensated to the water temperature to produce an accurate level measurement. It is an all-welded, stainless steel sensor, give accurate readings at pressure ranges from 0.7PSI, the all-welded design eliminates the need for an O-Ring seal, thereby eliminating potential leak paths. A unique cable seal ensures the water-tight integrity of the unit.
piezoresistive differential pressure sensors adopt the high steady and high accuracy piezoresistive differential pressure transducer sensing element with stainless steel isolated construction, silicon oil is filled in between the chip and two diaphragms. The measured differential pressure is transmitted onto the chip through the diaphragm and silicon oil. The signal output generated by the piezoresistive bridge sensor is amplified into a useable voltage or 4-20 mA output as specified by customer. Rugged housing with all stainless steel integrated structure. Various kind of pressure connection and easy for installation. The whole product is used for differential pressure measurement of petroleum, chemistry industry, power station and hydrology....
Low cost piezoresistive pressure sensors designed with the compact structure and the standard industry 1.0% accuracy, meet the purpose of lower down the cost, are the premium products of the sendo OEM-line, it is a very classic sensor used in automotive applications, smart size, beautiful appearance, light weigh only about 50g, all these make low cost pressure sensors suitable to the applications with limited space and weight. They use a high steady piezoresistive pressure transducer which have stainless steel 316L as the diaphragm, and provide an output signal with 0.5~4.5V or 1~10V, can be wildly used in automotive, pump, A/C, HVAC and other accuracy not critical filed. The stainless steel housing and brass housing is for optional.
Piezoresistive pressure transducers are fundamentally a device that converts an applied pressure into an electrical signal. It also can be called: piezoresistive OEM capsules or piezoresistive pressure sensor elements. A high-sensitivity piezoresistive silicon chip is used for pressure sensing. The chip is protected against ambient influences by 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.
Resistance temperature detectors (RTD) accurately sense temperature with an excellent degree of repeatability and interchangeability of elements. The RTD is composed of certain metallic elements whose change in resistance is a function of temperature. In operation, a small excitation current is passed across the element, and the voltage, which is proportional to resistance, is then measured and converted to units of temperature calibration. The RTD element is manufactured by winding a wire (wire wound elements) or plating a film (thin film elements) on a ceramic or glass core and sealing the element within a ceramic or glass capsule.
