Hydro-Probe Orbiter Moisture Sensor
The Hydro-Probe Orbiter microwave moisture sensor consists of two parts, the head unit which contains the electronics, and the sensing arm, which takes moisture readings. The arm is easily replaceable and cuts through the mix providing a rapid measurement of both moisture and temperature of the material. To extend the wear life of the arm, Hydronix recommends that in all cases the arm is protected from excessive wear by use of a arm guard and protection rings.
Rapid Response to Moisture Changes
Unlike other sensors which are positioned so that the material flows over the sensor face, the Hydro-Probe Orbiter is designed to move rapidly through the mix. This provides a very fast response to changes in moisture.
A temperature sensor in the ceramic at the end of the sensing arm provides a fast response reading, enabling temperature correction for adjusting water addition, or for controlling steam heating equipment.
The Hydro-Probe Orbiter is installed approximately 50mm above the floor of the mixer. This provides a faster response to added moisture in the mix.
Easy to Install
The Orbiter is easy to install and there is no requirement to cut a hole in the mixer floor.
Easy to clean by hosing/brushing to remove build up of materials. Regular checking for wear is required.
No Build Up
Unlike floor mounted sensors, the Orbiter is not affected by uneven mixer floors.
Replaceable Sensor Arm
The main sensor body and electronics are positioned out of the mix, and should not have to be changed. The sensing arm is available as a replacement item, so when worn or damaged, the sensing arm may be changed with only minimal disruption to production.
Different Arm Lengths
Various arm lengths are available depending on the mixer type and fixing position
For applications using a static pan mixer a rotating connector is available which provides a reliable connection to the Orbiter while allowing it to rotate.
