VEGA VEGAWAVE 61 Tuning Fork Level Switch for Powders

A tuning fork switch for very light, adhesive or abrasive powders

The VEGAWAVE 61 is VEGA’s tuning-fork level switch for powders and fine-grained bulk solids. Where the VEGAVIB rod detects solids from 0.02 g/cm³, the VEGAWAVE fork reaches down to 0.008 g/cm³ and is, per the product information, very rugged and insensitive to buildup, which VEGA says makes it ideal for adhesive and abrasive products and bulk solids of very low density. The specification sheet describes the compact relay (DPDT) version with 20…253 V AC or 20…72 V DC supply, a process pressure of -1 to +25 bar and temperatures from -50 to +250 °C.

Technical specifications

Fork versus rod in practice

VEGA’s own comparison is the useful guide: the fork detects very light solids from 0.008 g/cm³ and is rugged against buildup, whereas the rod is the choice where granules might otherwise jam between fork tines. The thread starts at G1½, so the nozzle needs to be larger than for a VEGAVIB, which uses threads from 1″.

Ordering and approvals

The housing, electronics (relay, transistor, contactless switch, two-wire and NAMUR) and the plug connector are all selectable, and the PLICSLED module can show the switching status through a transparent lid. Product information lists approval status, and the optional SIL2 qualification applies to the version described. Provide product, density, temperature, pressure, thread or flange and output when you request a quotation, and confirm hazardous-area marking before ordering.

As with other series 60 switches, the status can be seen on site with the PLICSLED display module, and the housings are offered in plastic, stainless steel and aluminium. The sheet states that the instruments are suitable for use in hazardous areas and approved, for example, according to ATEX and IEC, with the exact approvals depending on the version. The pressure rating of 25 bar and the 250 °C limit with temperature adapter are the highest in the VEGAVIB and VEGAWAVE 60 series, which is why the compact fork is the usual candidate when the vessel is pressurised or hot and the product is a light powder; confirm the exact process fitting and seal for your pressure class.
