Hydro-Probe Orbiter - Technical Specifications
The Hydro-Probe Orbiter is a rugged, hard wearing, digital moisture sensor that has been designed for use in mixers. It can be static mounted for rotating pan mixers or conveyor belt applications, or can be used as a rotating sensor, fitted to the mixer arm in static pan mixers.
Construction
- Body: Stainless Steel (AISI 304)
- Sensing head: Hardened stainless steel. (wear resistant surface coating also available.)
- Faceplate: Alumina ceramic
Material Penetration
Approximately 75-100mm, dependent on material.
Power Supply
+15V to 30V DC, 4 Watt max.
Digital Communications
Opto-isolated RS485 2-wire port.
Refresh Rate
Outputs are updated approximately 25 times per second.
Moisture Range
The sensor will measure up to saturation of material. This is usually around 15% in standard concrete mixes but may be higher in lightweight aggregates or other materials.
Inputs and Outputs
Available for applications when sensor is static, and connected by standard cable.
Analogue outputs: Two configurable outputs 0-20mA or 4-20mA current loop source available for moisture and temperature. Also may be converted to 0-10 V dc.
Discrete inputs/outputs: Two inputs available for "batch average", start/stop or moisture temperature multiplexing. One output available to indicate "out of range".
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
Operating Temperature
The standard Hydro-Probe Orbiter operates to a temperature of 0-60 Degrees C but will not measure in frozen materials. The high temperature option will work in materials with a temperature of up to 120 Degrees C as long as the electronics can be kept to a temperature of 60 Degrees. Note: this item is special order.
