Hydro-Mix Microwave Sensor
Technical Specification

The Hydro-Mix is a rugged microwave sensor designed to measure moisture in manufacturing industries that use mixers and blenders during processing. Typical applications that use this sensor are aggregates, concrete and asphalt production.
Construction
- Body: Stainless Steel
- Protection Ring : Hardened Steel
- Faceplate: Ceramic
Fixing
The Hydro-Mix is secured to a fixing plate by a clamp ring. This allows the height of the sensor to be adjusted if necessary.
Analogue Outputs
2 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
2 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. Ethernet and USB interfaces are also available.
Moisture Range
The sensor will measure up to saturation of material.
Material Penetration
Approximately 75-100mm dependent on material.
Operating Temperature
0-60 degrees C. The sensor will not measure in ice.
Refresh Rate
Outputs are updated 25 times per second.
Connections
The sensor is fitted with a 10-way MIL-SPEC connector. A 4, 10 or 25 metre, 6 twisted pair cable pre-assembled for connection to a waterproof junction box is available.
Power Supply
+15Vdc to +30Vdc. 4W
