Product overviewMeasuring transducer for moisture monitoring in continuous material flows and in hard-to-access locations such as tower dryers. Provides volumetric moisture measurement in heterogeneous bulk materials using TRIME technology. Intended for grain and feed processing.
Applications- Grain & feed
- Continuous material flow measurement
- Tower and inline dryers
Technical data- Temperature range: 0°C ... +70°C (electronics); measuring head: 0°C ... +120°C (briefly to 150°C)
- Power supply: +12V to +24V DC, approx. 3 W
- Signal outputs: 2 × analogue 0(4)...20 mA — Output 1: humidity (%); Output 2: temperature (or conductivity / standard deviation)
- Interfaces: RS485 or IMP bus
- Sensor dimensions: 175 × 80 × 58 mm (L×W×H); probe Ø70 × 235 mm
- Weight: 1.3 kg
- Ingress protection: IP65
- Special condition: measuring head can be briefly exposed to 150°C
Variants- Round sensor GRr, with stainless-steel cap on temperature sensor
- Construction variant: Keilsonde WS2
Installation- At dryer inlet
- Directly in dryer before and during drying
- In dryer outlet (discharge hopper or discharge conveyor)
- For grain transport, e.g. in hoppers
Accessories (selected)- SONO-View: Stand-alone display and configuration unit for process control; supports up to 4 SONO probes via serial interface
- SM-USB: USB to RS485/IMP bus converter for PC connection; used for calibration, test measurements and data logging
- Cables: SONO sensor cable (4 m, 10 m, 25 m), 6 twisted pairs, shielded, 10-pin MIL connector; fixed gland variants IP67
- Blind cap: Plastic Hibro, M70x2
- Lock nut: Aluminium, M70
- Flange: GR aluminium mounting flange 120 × 120 mm
Technical specifications- Measurement principle: TRIME — volumetric penetration of approx. 2 dm³
- Measuring range: up to 70% moisture; resolution in dry range down to 0.05%
- Sensor material: temperature-stable PEEK for measuring head
- Suitable for heterogeneous bulk solids; measurement independent of grain type, product temperature and ionic conductivity
- Designed for continuous operation and PLC integration
