Hydro-Mix VII Microwave Sensor - Technical Specification
The Hydro-Mix VII 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 varied but include the concrete industry, asphalt production, animal feed and grain processing.
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.
Moisture Range
This is dependent on material properties.
Material Penetration
Approximately 75-100mm dependent on material.
Operating Temperature
0-60 degrees C. The sensor will not measure in ice.
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/Outputs
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.
Refresh Rate
Outputs are updated approximately 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.
Measured Values
Including: Instantaneous (smoothed) unscaled and moisture percentage; Filtered unscaled and moisture percentage; External temperature 0-60 degree C +/-1 degree C. Digital filtering can be configured from the Hydro-Com Diagnostic software to condition the sensor reading to suit the application.
Power Supply
+15Vdc to +30Vdc. 4W
Grounding
The sensor body is connected to the cable shield. Power input and signal interfaces are galvanically isolated both from the sensor case and from each other. Ensure equipotential bonding of all exposed metalwork.
