    During work on and with the device, the required personal protective equipment must always be worn. Appropriate use VEGAFLEX 83 is a sensor for continuous level measurement. You can find detailed information about the area of application in chapter "Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in this document as well as pos- sible supplementary instructions.

  • Page 7: Product Description

    Optionally an autoclaved version with separable housing is available. Due to the qualification up to SIL2 or homogeneous redundant up to SIL3 (IEC 61508) the VEGAFLEX 83 is suitable for the use in safety- instrumented systems (SIS). The safety function (SIF) can be a monitoring of the max. or min. level or a combination of both.

    End segment: 26 … 480 mm (1.02 … 18.9 in) Centering If you mount the VEGAFLEX 83 in a bypass tube or standpipe, you have to avoid contact to the bypass tube by using a spacer at the probe end.

  • Page 13: Mounting Instructions

    The guided microwave principle requires a metallic surface on the process fitting. Therefore, in plastic vessels, etc., use an instru- ment version with flange (from DN 50) or place a metal sheet (ø > 200 mm/8 in) beneath the process fitting when screwing it in. Make sure that the plate has direct contact with the process fitting. When mounting rod or cable probes in vessels without metal walls, e.g. in plastic vessels, the measured value can be influenced by strong electromagnetic fields (emitted interference according to EN 61326: class A). In this case, use a probe with coaxial version. VEGAFLEX 83 • Two-wire: 4 … 20 mA/HART...

Autoclaved version For use in an autoclave, e.g. for sterilization, the VEGAFLEX 83 is available as autoclaved version. Hence you can separate the housing from the process fitting. Under very harsh ambient conditions, the autoclavable version can be optionally also combined with an external housing.
