VEGA radar gains -170°C ATEX approval
15 January 2007
Liquid gases stored at low temperatures are often also in ATEX zoned areas particularly LNG, propane etc. In some products and cryogenic processes, the temperatures can get very low indeed and the standard ‘T’ (temperature) class of the instrument in the ATEX certificate can be no longer valid. VEGA, the market leaders in process radar, have now gained a unique ATEX approval for applications down to (minus) -170°C to +150°C. The approved device is the VEGAPULS 63, a 2-wire loop powered non-contact radar transmitter with flush transmitter face in TFM-PTFE.
These radar devices incorporate a special separator to protect the electronics against the very low temperatures and this also allows complete isolation of the process connection, whilst the electronics remain completely accessible. Even with the housing at ambient temperatures down to –40°C, the electronics can still function reliably. These devices are versatile to mount and can be fitted onto a ball valve for complete process isolation and/or used in a simple stilling or guide tube to carry out the measurement.
