Stable Hydrostatic Level Transmitter 4-20mA

A precision hydrostatic level measurement solution based on diffusion silicon technology, housed in a hermetically sealed stainless steel probe with internal silicone oil fill. It operates on AC220V and provides a linear 4–20mA output corresponding to liquid height. At ~521g, it combines portability with industrial-grade durability. Its wide temperature compensation and resistance to foaming, crust build-up, and media viscosity changes make it suitable for continuous monitoring in dynamic liquid environments. Installed across UK water authorities’ assets, European wastewater treatment lines, offshore oil storage, mine dewatering systems, and environmental monitoring buoys — reliably serving from urban rooftop tanks to submerged seabed observatories at 200m depth.
