8136 OEM Radar Measuring Device
Brand: Burkert Fluid Control Systems
The Type 8136 is a non-contact radar level measuring device for continuous level measurement.
The unit is available in two versions:
- with encapsulated horn antenna particularly suitable for level measurement of aggressive liquids in small vessels
- with plastic horn antenna particularly suitable for measurement in open flumes or gauge measurement in waters
- For level measurement up to 20 m, 4 to 20 mA/Hart - 2-Wires
- Adjustable via Display, key operation or PC-Tool with DTM
- ATEX approvals
- Insensitive to variations of temperature, pressure, medium data of the product and gas layers
