Moisture Measurement In Bulk Material (Hydroprobe-II)
Our microwave sensors are made of high graded raw material by using sophisticated machines and latest technology. These can be fitted with standard sleeve and extension mounting kit.
The features and specifications are as follow:
Construction:
- Body: cast stainless steel (ANC3B 18/8SS)
- End cap: 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:
- 0-600C
- The sensor will not measure moisture in frozen materials
Refresh rate:
- Outputs are updated approximately 25 times per second
Extension cables HP02T HP02C:
- Type: 5 pairs twisted with overall screen 4 core with overall screen
- Wire size: 7/0.203mm (24awg 0.22 mm2) 16/0.2mm (0.5,mm2)
- Impedance: 92p/km 40/km
- Capacitance: 98pF/m 98p/km
- Max length: 90m with 15V supply 110m with Hydro-View
- 400m with 24V supply
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:
- Up to isolated RS485 2-wire port
Grounding:
- The sensor body is connected to the cable shield ensuring potential bonding of all exposed metalwork
Note: In areas of high lightning risk correct and adequate protection should be used.
