Industrial pressure transmitter - Model PKCM

Pressure transmitter PKCM

Product description

Equipped with a tri-clamp fitting, the PKCM is a compact, rugged pressure transmitter with a sanitary flush diaphragm that utilizes the latest leading-edge technologies to measure pressure. With its excellent stability and proven reliability, the PKCM provides unequaled performance and is designed for any application that requires a low to medium pressure measurement.

The sensing element is a solid-state, piezoresistive MEMS 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 316L stainless steel package and is completely isolated from the media.

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 electronic circuit is packaged in a hermetically-sealed, all-welded 316L stainless steel housing enabling the PKCM to be immersed in water or pressure washed without internal leakage (depends on termination). This design makes the PKCM ideal for pressure measurements that can involve wet, corrosive or sterile media in the most severe environments.
