Description
The E+E EE364 is a compact moisture-in-oil sensor for online monitoring of transformer, engine, lubrication and hydraulic oil and diesel fuel. It measures water activity from 0 to 1 aw with ±0.02 aw accuracy and oil temperature from −40 to +100 °C with ±0.2 °C accuracy, and calculates the absolute water content in ppm.
The data is available on two scalable 4–20 mA outputs and on RS485 with Modbus RTU. The 316L stainless steel housing is pressure-tight to 20 bar and rated IP65, and mounts with a G ½ or ½ in NPT thread.
Argonmark Ltd supplies E+E Elektronik instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
