EST3100 Economical Pressure Transmitters


EST3100 Economical Pressure Transmitters

EST3100 Economical Pressure Transmitters are cost-effective pressure measuring devices for both civil and industrial purposes. The product is widely used for the measurements of gas and liquid, such as water, oil and light corrosive liquid and gas. Adopting 1Cr18Ni9Ti stainless steel construction, sensors of international brands, and the sensor-special amplifying circuit, the product is easy for zero/span trim. Apart from dozens of standard constructions and output types, we are ready to customize products based on your requirements for batch application

Piezoresistive based transducers rely on the piezoresistive effect which occurs when the electrical resistance of a material changes in response to applied mechanical strain. In metals, this effect is realized when the change in geometry with applied mechanical strain results in a small increase or decrease in the resistance of the metal. The piezoresistive effect in silicon is due primarily to changes at the atomic level and is approximately two orders of magnitude larger than in metals.

Sputter deposited thin film pressure sensor is a kind of Piezoresistive pressure sensors, difference exist that the thin-film sensor consists of a resistor pattern that is vaporized or sputter-deposited  onto the force-summing element (the measuring diaphragm). In some transducers the resistors are not directly mounted on the diaphragm but are on a beam linked to the diaphragm by a push rod.
