Submersible level transmitter - Model PL2H

Level transmitter PL2H

Product description

Senzors’ model PL2H is a compact, rugged submersible level transmitter that utilizes the latest leading-edge technologies to measure hydrostatic pressure. The PL2H is a durable and accurate level probe specifically designed for demanding applications where the primary criteria are reliability and low cost. 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 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.

Providing excellent media compatibility with all 316L stainless steel wetted parts, it is perfectly suited for applications where media compatibility is a problem. With its high stability, low cost and proven reliability in harsh environments, it is ideal for OEM applications. A modular design allows the use of different materials and cables.
