PROTRAC: Radiometric point level detection

Radiometric point level detection operates with a radioactive source that emits focussed gamma radiation. The radiation is picked up by a detector on the opposite side of the vessel. When the gamma rays are blocked by the medium, the detector receives little or no radiation. The intensity changes of the incoming radiation are forwarded as signals by a relay.

The advantages

  • Maximum operational reliability even in the harshest environments
  • Measurement is unaffected by pressure, temperature and product corrosiveness
  • Measuring system can be installed on outside of vessel during ongoing production

Step by step to the right sensor

Function

Radiometric measurement is based on the gamma rays, i.e. radiation, emitted by an isotope. The sensor, located on the opposite side of the vessel, receives this radiation. The detector of the sensor converts the gamma radiation into signals, the number of which is recorded and evaluated.

Series

Detector = POINTRAC

Mounting

The radioactive source is mounted on one side of the container and the detector on the opposite side. For level detection, the sensor is usually mounted horizontally at the height of the desired limit level.

Connection

A three-core installation cable with PE conductor is required for power supply. The 4 ... 20 mA current output is connected with standard two-wire cable.

Setup

Due to the measuring principle itself, there is no linear relationship between the pulse rate and the level. For that reason, an adjustment must always be carried out.
