ProGap – Microwave level Switch

For Contactless detection of dry bulk solids

The microwave barrier, ProGap is a universally and flexibly usable sensor, consisting of a transmitter and a receiver based on the latest microwave technology. It is brought into action for level detection or for positioning of items. The instrument can be installed in containers, pipelines, shafts or at free-falling sections.

The ProGap can also be applied in difficult circumstances like high temperatures and pressures and dust EX-zones by means of a process adapter. By using microwaves there is a high insensitivity to built-up on the sensor window.

Features

  • Technical Specifications
  • Applications
  • Operating Principle
  • Housing: Stainless Steel
  • Operating Temperature: -20° C to 80° C
    • Option: Max 1000° C (with ceramic flange)
  • Pressure: Max 20 bar
  • Detection Range:0….4 m  0….18 m
  • Response Time: 0.25 s ... 5 s (continuously adjustable)
  • Measuring Frequency: K-BAND 24.125 GHz (± 100 MHz)
  • Power Supply: 24 VDC (-10/+15 %)
  • Power Consumption: Approx. 1.8 VA
  • Detection of Beer Foam
  • Monitoring of garbage incineration
  • Dosage of fluff in cement plant
  • Level detection at Cyclone hopper at high temperature(+900°C)

A microwave frequency of 24.125 GHz is generated from the sensor which is being received at the other end by sensor.  As soon as the change in the microwave frequency is detected at the received end due to level detection, the relay is activated.
