Hydro-Probe SE dimensions

The Hydro-Probe SE is a digital, microwave sensor designed to measure moisture in flowing materials. Typical applications include moisture measurement in industries that use a pressurised vessel, calandria or dryer as part of the process.

Construction

  • Body: 316 Stainless steel
  • Faceplate: Ceramic
  • O-Rings: EPDM

Fixing

The sensor must be placed in the flow of material and is bolted to a flange mounting which is welded to the vessel.

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.

Material Penetration

Approximately 75-100mm material dependant

Environmental

  • Pressure: Full vacuum to 5 Bar gauge
  • Electronics Section Protection: IP67

Measurement Range

  • Moisture: 0-100% material dependant
  • Brix: >50º Bx

Operating Temperature

  • Materials Section: 0-125ºC
  • Electronics Section: 0-60ºC

The sensor will not measure 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
