Process Automation > Gamma Point Level Gauges

The Process Automation gamma type level switch is used to determine the level in vessels at a particular point. These gauges are ideal for level measurement in mining and other harsh applications where other techniques do not offer the reliability required.

Operation
The point level gauge operates on the principle of gamma ray absorption.

It comprises a gamma emitting source and an appropriate gamma detector, mounted on opposite sides. As the process level rises, the detector is shielded from/to the gammas due to the absorption of the gammas in the process material. The detector provides a volt free relay output to indicate a change in status.

One gamma source may serve more than one level detector for multi-point measurement applications, e.g Low & Low-low Alarm, etc.

This non-invasive measurement is unaffected by process pressure, temperature, dust, viscosity, refractive characteristics, etc. and does not suffer wear and corrosion normally associated with invasive measurement systems.

The gamma detectors may be supplied in either of two formats viz. Detector with Remote mounting transmitter electronics or detector with integrated processing electronics.
