Hydro-Probe II

Hydro-Probe II fitted with standard mounting sleeve (A/HP/SL)

Hydro-Probe II fitted with extension mounting kit (A/HP/XK)

Construction
Body: cast stainless steel (ANC3B 18/8SS) Endcap: stainless steel (AISI 316) Faceplate: alumina ceramic

Range of moisture
For bulk materials the sensor will measure up to the point of saturation, typically 0-20% for construction materials.

Penetration
Approximately 75-100mm dependent on material.

Power supply
+15Vdc to +30Vdc. 3 watts max.

Operating temperature
0-60 degrees C. The sensor will not measure moisture in frozen materials.

Refresh rate
Outputs are updated approximately 25 times per second.

 

 

 

Analogue output
Configurable 0-20mA or 4-20mA current loop source. For 0-10Vdc output an external 500R load resistor should be connected across the analogue output at the control system.

Discrete inputs
The batch average start stop or moisture/temperature multiplexing functions can be controlled via the digital inputs. Refer to 'Connecting the Cable' section of the manual for more information.

Digital Communications
Opto-isolated RS485 2-wire port. Refer to your distributor for read/write access to sensor parameters and values.

Grounding
The sensor body is connected to the cable shield. Ensure equipotential bonding of all exposed metalwork. In areas of high lightning risk correct and adequate protection should be used.
