Hydro-Mix - Model XT-EX - Flush Mount Digital Microwave Moisture Sensor for Hazardous Locations (Dust)
From Sensor - Hazardous Locations
The Hydro-Mix XT-EX has been designed to measure moisture in flowing bulk solids such as animal feed, grain, rice, pulses and also in liquids. The sensor can be easily installed in ducting, conveying and mixing systems. It is suitable for Zone 20 process environments (Zone 21 external to process). Comprising a single, intelligent unit that contains all on-board functionality including signal processing and averaging, the Hydro-Mix XT-EX precisely measures the moisture content of material passing over the ceramic faceplate. Remote configuration, calibration, diagnostics and firmware upgrades are simple using Hydronix Hydro-Com software. The linear output allows direct integration with any control system using industry standard interfaces.
