Pressure sensors, transducers, and PS85-102A-N2GF are frequently used in applications such as industrial process control, oil and gas, automotive, HVAC (heating, ventilation, and air conditioning), medical, and consumer electronics. The PS85-102A-N2GF is a four-wire system that uses a temperature compensated resistance strain gauge cell to produce a robust, reliable and safe measurement for applications with a differential pressure up to 20 psi.

The working principle of the PS85-102A-N2GF is based on the Balanced Wheatstone bridge circuit. This balance Wheatstone bridge circuit is powered by a low-voltage power supply and includes temperature-compensated strain gauge elements. In fact, the bridge is composed of four active arms whose resistances are electrically connected in pairs and whose outputs are sampled by a differential pre-amplifier that sends the amplified voltage back to a processor from which the pressure reading is derived.

The strain gauge element is a semiconductor-type device that is based on the principle of resistance strain. This basically utilizes the linearity of the resistance with respect to the change in stress. This strain gauge element consists of a grid of parallel conductors that produces a voltage signal proportional to the applied pressure on the grid. The grid of conductors acts as a spring or an elastic medium that changes its resistance due to the applied pressure. This sensitivity of the strain gauge is affected by temperature variations and therefore needs to be compensated. This is achieved by using temperature compensation circuits that are placed in series with the Wheatstone bridge circuit.

The PS85-102A-N2GF pressure sensor is a very accurate and reliable device for measuring changes in pressure over a wide range in industrial, oil and gas, automotive, HVAC and medical applications. Furthermore, the temperature-compensated circuit of the PS85-102A-N2GF ensures that the output readings will remain stable under extreme temperatures. In addition, it also provides noise suppression and thermal drift reduction that make it ideal for use in harsh environments. As a result, it can be used to accurately measure pressures ranging from 0 to 20 psi and provide reliable readings even in extreme conditions. In conclusion, the PS85-102A-N2GF is an ideal choice for applications requiring high accuracy and stability, as well as reliable performance in a wide range of temperatures.
