Industrial pressure transmitter - Model PT1M
Senzors’ model PT1M is a compact, rugged, versatile pressure transmitter that utilizes the latest leading-edge technologies to measure pressure. With its excellent stability and proven reliability, the PT1M provides unequaled performance and is designed for any application that requires a low to medium pressure measurement. Its modular design makes it a general-purpose industrial pressure transmitter 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 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. There are no internal O-rings or elastomers to contain the media and to contribute to instabilities or drifts.
The sensor signal is amplified by state-of-the-art ASIC-based electronics which provides a high-level output from an unregulated voltage supply and a fast response time with no latency, thanks to analog signal processing from end to end. The ASIC enhances accuracy while reducing the transmitter’s size. Coupled with MEMS technology, it also enables Senzors to offer almost any output over any pressure range. 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 PT1M to be immersed in water or pressure washed without internal leakage. This design makes the PT1M ideal for pressure measurements that can involve wet, corrosive or sterile media in the most severe environments.
