Hydro-Mix HT Microwave Sensor
Technical Specification

The Hydro-Mix HT is a microwave sensor designed to measure at high temperature in manufacturing industries that use drying, ducting, conveying and mixing systems during processing.
Construction
- Body: 316 Stainless Steel (Food Safe)
- Faceplate: Ceramic (Food Safe)
- Internal Seals: FDA approved O-Rings
Fixing
The Hydro-Mix HT is flush mounted with the internal wall using the included mounting assembly.
Analogue Outputs
Two configurable 0-20mA or 4-20mA current loop source available for moisture and temperature. May also be converted to 0-10V DC.
Digital Inputs/Output
Two configurable digital signals are provided for batch average start/stop or for moisture / temperature multiplexing purposes.
Digital (Serial) Communications
Opto-isolated RS485 2-wire port. Uses Hydro-Com communications protocol for read/write access to sensor parameters and values. RS232 converter, Ethernet and USB interfaces are also available.
Measurement Range
- Moisture: 0-100%, material dependant.
- Depth: Approx. 75-100mm, material dependant.
