Piezoresistor pressure sensor is a sensor made of piezoresistor effect of monocrystalline silicon and integrated circuit technology. When the monocrystalline silicon material is affected by the force, the resistivity changes, through measuring circuit, ratiometric output signal to force change can be obtained. It is also known as the diffused silicon piezoresistive pressure sensor, which is different from the adhesive strain gauge which needs to feel the external force indirectly through the elastic sensitive element, but directly through the silicon diaphragm to feel the measured pressure.
RTD Resistance temperature sensor is usually made from high purity platinum metal. Their resistance has a direct and repeatable relationship with temperature.
RTD platinum temperature sensor has long term stability and strict tolerances over a wide temperature range. They are widely used in various electronic instruments, household appliance, HVAC, energy power industry and mechanical control.
The function of displacement sensor is to convert various measured value into electric quantity. In the production process, displacement measurement is generally divided into two types: physical size measurement and mechanical displacement measurement.
A load cell is a sensor that converts force or weight into a measurable electrical output, the most common output signal is mV/V.
