Industrial pressure transmitter - Model PI3H
Senzors’ model PI3H is an advanced, digitally compensated pressure transmitter which provides high accuracy and cost-effectiveness in one package. Equipped with the latest leading-edge technologies, it offers high precision, excellent stability and proven reliability in a compact, rugged design. It is the perfect solution for any application that requires a highly accurate, medium to high pressure measurement. Its modular design makes it a general-purpose industrial pressure transducer that can serve as the basis for a unique custom solution without sacrificing price and high performance.
The sensing element is a solid-state piezoresistive silicon die. This technology is based on a principle that results in excellent linearity, increased long-term stability and reliability and virtually no hysteresis. The silicon strain gage is fitted into a 316 stainless steel package and is completely isolated from the media. There are no internal O-rings or elastomers to contain the media and to contribute to instabilities or drifts.
The sensor signal is digitized, compensated and processed by a powerful, low power 32-bit microcontroller. It is then converted back to an amplified analog signal. The digital electronics ensures precise calibration of all critical parameters and achieves very high precision, thermal stability and compensation of all repeatable errors. Each unit is fully tested, compensated and calibrated for pressure and temperature. Each transmitter is shipped with a traceable calibration card.
The electronics is packaged in a hermetically-sealed all-welded 316 stainless steel housing enabling the PI3H to be immersed in water or pressure washed without internal leakage. This design makes the PI3H ideal for pressure measurements that can involve wet, corrosive or sterile media in the most severe environments.
