During work on and with the device, the required personal protective equipment must always be worn. Intended use VEGAPULS C 22 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.

Open the VEGA Tools app and enter the serial number under "Documentation". Principle of operation Application area VEGAPULS C 22 is a radar sensor for non-contact, continuous level measurement. It is suitable for liquids and solids in practically all industries. The instrument emits a continuous, frequency-modulated radar signal Functional principle through its antenna. The emitted signal is reflected by the medium...

For the wall mounting, a mounting bracket with opening for thread Mounting bracket G1½, e.g. from the VEGA product range, is recommended. The mounting of the device in the bracket is carried out via a G1½ counter nut of plastic. Take note of chapter "Mounting instructions" for the recommended distance to the wall.

The centre of the antenna lens is the beginning of the measuring range and at the same time the reference plane for the min./max. adjustment, see following diagram: Fig. 9: Reference plane Reference plane Inflowing medium Do not mount the instruments in or above the filling stream. Make sure that you detect the medium surface, not the inflowing product. VEGAPULS C 22 • Modbus and Levelmaster protocol...

(0.2 in) out of the socket. Fig. 11: Recommended threaded socket mounting of VEGAPULS C 22 If the reflective properties of the medium are good, you can mount VEGAPULS C 22 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. Note: When mounting on longer nozzles, we recommend carrying out a false signal suppression (see chapter "Parameter adjustment").

This status message is inactive by default. Maintenance required: Due to external influences, the instrument function is limited. The measurement is affected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup). This status message is inactive by default.
