Submersible level transmitter - Model PL1H
Senzors’ model PL1H is a rugged, versatile submersible level transmitter that utilizes the latest leading-edge technologies to measure hydrostatic pressure. With its excellent stability and proven reliability, the PL1H provides unequaled performance and is designed for any application that requires a high level measurement. Its modular design makes it a general-purpose submersible level probe that can serve as the basis for a unique custom solution without sacrificing price and high performance. Different materials and cables are available.
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 amplified by conventional analog electronics which provides a high-level output from an unregulated voltage supply and a fast response time with no latency, thanks to pure analog signal processing. 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 PL1H to be immersed in water without internal leakage. This design makes the PL1H ideal for level measurements that can involve hostile liquids in the most severe environments.
