RF Admitance Level Sensor by N.D. Automation

N.D.AUTOMATION is widely applied in various sensor. These comprise of a specially designed electronics and sensing probe using Driven Shield Coat Guard circuit and corresponding 3-Element Probe. The electro-mechanical combination of the Driven Shield technique makes the system immune to the material build-up on the probe and material bridging between the probe and the hopper wall. The measured signal does not flow to the hopper wall through the probe in the backward direction but flows only through the material.

The salient features of this level measuring instrument are as follow:

• Three Element Coat Guard Technology
• Can be configured either for High or Low Level point switching
• Ignores material build-up on the probe
• Suitable for the highly dusty environment
• High Reliability
• Fast and Easy Installation Simple Calibration
• Field selectable operation logic
• Provides economical solutions
• Various models not required
