Hydro-Probe II Digital Moisture Sensor - Features
The Hydro-Probe II is a digital moisture sensor that is designed to measure moisture continuously in the flow of material across the ceramic sensor faceplate. Reading at 25 times per second the sensor detects rapid changes in moisture, providing a linear digital or analogue output.
Calibration
The sensor may be internally calibrated using the Hydro-Com software, or the linear output may be calibrated within the control system or by use of the Hydronix Hydro-View calibration unit.
Matching Characteristics
During manufacture every sensor is calibrated to a standard air and water reading. This means that every unit that leaves our factory measures identically ensuring that sensors can be easily replaced without the need for re-calibration. Using a pc via either a USB module or Ethernet Adapter and Hydronix Hydro-Com software, the new sensor can be easily reconfigured to match the sensor being replaced.
Simple Power Requirements
The Hydro-Probe II may be powered from a 15-30V dc supply. Multiple sensors may be driven from a single power source.
Temperature Measurement
Temperature output is available to provide read-out of material temperature.
Inclination of Measurement Face
A unique feature is the 'angling' of the sensor face plate to the flow of the material. This ensures consistent flow characteristics over the sensor face and prevents build up or "clogging" of the material at the sensor. The normal angle is 60 degrees from the direction of the flow but this may be easily adjusted to suit the flow characteristics of any material.
Batch Averaging
The 'averaging' mode continuously provides the 'average' reading of moisture from the start of reading to any time selected - normally the closing of the hopper door. Averaging, bin empty alarms and signal processing performed internally by sensor.
