Hydro-Probe dimensions

The Hydro-Probe is a rugged, digital, microwave sensor designed to measure moisture in flowing materials. Typical applications include moisture measurement in abrasive materials such as sand, aggregates and concrete.

Construction

  • Body: Stainless Steel
  • Faceplate: Ceramic

Fixing

The sensor must be placed in the flow of material.

Bins and Silos:- Install in the neck of a bin or underneath the gate. Standard and Extension Mounting Sleeves are available to suit different bin widths.
Conveyors:- Secure in the flow of material

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
