VEGA VEGACAP 67 High-Temperature Capacitive Level Switch 400 °C

A 400 °C capacitive probe for hot bulk solids

The VEGACAP 67 is the high-temperature member of VEGA’s capacitive switch family, a point level sensor for bulk solids with a process temperature rating of -50 to +400 °C. It comes as a rod up to 6 m or a cable up to 40 m, the wetted parts are stainless steel, and the probe insulation is made of ceramic. The sheet describes the transistor (NPN/PNP) version, powered from 10 to 55 V DC, and lists a pressure rating of -1 to +16 bar, which suits hot silos for cement clinker, ash, foundry sand and hot granules rather than pressurised vessels.

Technical specifications

Handling heat

At 400 °C the electronics cannot sit at the process temperature, so the sheet separates the figures: the ambient, storage and transport temperature stays at -40 to +80 °C while the probe itself is rated to +400 °C. Installers should therefore check the temperature at the housing against the manufacturer’s derating information and the insulation of the vessel wall, since a hot nozzle and a long insulated roof can raise housing temperature beyond the ambient limit.

Selection and ordering

VEGA’s stated benefits are universal use in bulk solids through the wide temperature range, long life with low maintenance, and the flexibility of a shortenable probe. Choose the rod for a short extension from a side wall or the roof, and the cable for deep silos where a point level far below the roof is needed. The maximum pressure is 16 bar, lower than the VEGACAP 65 or 66, so the 67 is chosen for temperature, not pressure.

For an RFQ give the probe type, length, thread or flange, product, temperature and supply. The sheet notes that other electronics versions exist, namely contactless electronic switch, relay and a two-wire type, so please confirm the right version and any ATEX, IEC or ship approval with the manufacturer before ordering.
