4 - 20mA Gauge Water Level Transmitter 316L Stainless Steel Housing PL301
ATECH PL301 4-20mA Gauge Water Level Transmitter
PL301 series level transmitter carefully selects high-reliability silicone piezoresistive or ceramic capacitors or sapphire sensors as the pressure sensitive core according to different industry applications. After automatic temperature compensation, programmable digital circuit correction and signal conditioning, the products output the standard industrial application and networking signal. The production process continues the rigorous work style and fine process control of military enterprises. Each type of product has been carefully designed, component screening, process curing, and through pressure cycle distressing, aging, environmental simulation testing, etc., to ensure each is stable and reliable.

Description PL301 Submersible level transmitter
The PL301 Submersible Level Transmitter / Hydrostatic Level Sensor is designed for use in rivers, reservoirs, storage tanks, boreholes, vessels and channels. They have long-term immersion protection to 100 meters and are also ideal for measuring pressure in submerged pipes and vessels.
For applications with aggressive media such as seawater or leachate, especially landfills, we can offer submersible level transmitters in high-grade duplex stainless steel with extremely high corrosion resistance.
Electrically interface with hydrostatic level transmitters using triple-sealed back-end assemblies and custom vented PUR cables. This provides the barometric pressure reference and guarantees IP68 integrity to a water depth of 100m.
The output of the standard level transmitter is a two-wire 4-20mA signal with a surge protection circuit to reduce the effects of electrical transients caused by nearby lightning strikes and power fluctuations. For applications using a data logger, a ratiometric version is available which provides a 0.5-4.5Vdc output from a 5Vdc supply.
