Hydro-Probe Digital Moisture Sensor
Features
The Hydro-Probe is a digital moisture sensor that is designed to measure moisture continuously in the flow of material across the ceramic sensor faceplate. Measuring at 25 times per second the sensor detects rapid changes in moisture, providing a linear digital or analogue output.
Digital Technology
Digital technology provides precise, linear moisture measurement.
Advanced Digital Signal Processing
The sensor response may be adjusted remotely using the Hydro-Com software to minimise the effects of noise of the measured signal. Advanced Digital Signal Processing provides a clear signal with a rapid response.
Fully Temperature Compensated Measurement
The sensor internally adjusts for mechanical changes due to temperature fluctuations
Easy to Interface
wo analogue outputs and digital RS485 communications and configurable digital inputs / output make the sensor simple to integrate into a control system.
Measuring in the Mix
Measuring at 25 times per second the sensor continuously detects changes in the moisture of the materials throughout processing.
Temperature Measurement
Temperature output is available to provide a readout of material temperature.
Sensor Configuration
The Hydro-Probe can be remotely configured using Hydro-Com diagnostic software. All readings and sensor parameters are available including the type of output and filtering characteristics.
Positioning
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 sensor should be positioned at an angle of 60 degrees to 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.
Accuracy of Measurement
All measurements may, if required, be calibrated to an accuracy of +/- 0.2%. If used to reach a target the accuracy can be better than 0.1%
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.
Simple Power Requirements
The Hydro-Probe may be powered from a 15-30V dc supply. Multiple sensors may be driven from a single power source.
