Nidec Copal Electronics' P-2000, P-3000S, and P-8505 series are pressure transducers that use semiconductor sensor chips. This integrated production ensures that all these products meet Nidec Copal Electronics' high-quality standards and high-reliability. The pressure is sensed by the piezoresistive properties of the semiconductor. Voltage signals are proportional to the pressure and then sent to the unit that the transducers are in.
