Industrial pressure transmitter - Model PI1L
Featured with a state-of-the-art digital compensation and a modular design, the PI1L is our most accurate, most precise and most versatile pressure transmitter. It utilizes the latest leading-edge technologies to measure pressure and offers unequaled performance, excellent stability and proven reliability. The pressure transducer is designed for any application that requires a low pressure measurement. The modular design 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 provides excellent repeatability, 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 PI1L to be immersed in water or pressure washed without internal leakage. This design makes the PI1L ideal for pressure measurements that can involve wet, corrosive or sterile media in the most severe environments.
