Bestech Australia introduces the new CG300 series level sensors from NOHKEN.
Reflecting NOHKEN’s 30 years of experience in capacitance level measurement, the CG series of level sensors employs phase detection principle. The capacitance between the electrodes increases with material around the CG sensors, and associated frequency changes in the oscillation circuit processed by microprocessor. The change in capacitance value is detected by changes in frequency value and gives 4-10 mA output corresponding to the change.
The ZERO and SPAN points of CG300 series level sensors can be easily adjusted with a push button mechanism when the medium changes inside the tank. The sensitivity of the level sensor is 30-2000pF that can be used in a wide range of applications without changing the circuit board.
Unlike conventional voltage change detecting sensors, CG level sensors will not be affected by noise or resistance build-up, due to phase detection principle and automatic calculation to adjust output signals. There is no need to recalibrate in actual liquid as these sensors will input the same setting data in the same detecting conditions.
Key features of CG300 series level sensors:
- Designed for liquid level detection and measurement
- Accuracy of ±0.5% FS under operational temperature from -20°C to 60°C; -20°C to 150°C with heat proof option
- Maximum 100kPa operating pressure
- IP68 (electrode) and IP65 (housing) protection
- Choice of 4 models
