During work on and with the device, the required personal protective equipment must always be worn. Appropriate 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 the operating instructions manual as well as possible supplementary instructions.

This operating instructions manual applies to the following instrument instructions versions: • Hardware version from 1.0.0 • Software version from 1.2.0 Constituent parts Fig. 1: Components of VEGAPULS C 22 Radar antenna 2 Process fitting Electronics housing Cable outlet Type label The type label contains the most important data for identification and use of the instrument.
Power supply and signal The VEGAPULS C 22 can be operated at any data logger with SDI-12 processing interface. The sensors are powered via the +12 V line of the three-wire connection cable.
Adjustment via the signal The SDI-12 data communication is controlled by commands from the cable SDI-12 data logger via the signal cable. Fig. 4: Connection of VEGAPULS C 22 SDI-12 to the data logge Sensor Data logger Packaging, transport and storage Packaging Your instrument was protected by packaging during transport.
Threaded adapters enable simple adaptation of devices with stand- ard threaded fittings, e.g. to process-side hygiene connections. Mounting accessories The mounting accessories are used for stable mounting of the device at the measuring point. The parts are available in various versions and sizes. VEGAPULS C 22 • SDI-12...
Mounting bracket For the wall mounting, a mounting bracket with opening for thread 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. 8: 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 • SDI-12...

Fig. 10: 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 "...
