Specification sheet 4 … 20 mA/HART - two-wire, rod and cable probe TDR sensor for continuous level and interface measurement of liquids Technical data Measuring range ƲƲ Cable probe Measuring accuracy Process fitting Process pressure Process temperature Ambient, storage and transport temperature Operating voltage Application area With VEGAFLEX 81 you can measure all kinds of liquids essentially maintenance free. The sensor delivers precise and reliable measured values even in applications with steam, buildup, foam generation or condensation. VEGAFLEX 81 is a truly cost-effective level and interface sensor for your measuring task. Your benefit • The guided adjustment enables a simple, time-saving and reliable setup • Comprehensive diagnosis options ensure maintenance-friendly operation and thus high plant availability • Shortenable probes allow simple standardization and maximum flexibility in planning Function High frequency microwave pulses are coupled onto a cable or rod and guided along the probe. The pulse is reflected by the product surface. The time from emission to reception of the signals is proportional to the level in the vessel. VEGA Grieshaber KG, Am Hohenstein 113, 77761 Schiltach/Germany, www.vega.com Materials The wetted parts of the instrument are made of stainless steel. The instrument seal is made either of FKM, FFKM or EPDM. You will find a complete overview of the available materials and seals in the "configurator" on our homepage at www.vega.com/configurator. Housing versions The housings are available as single chamber or double chamber version in plastic, stainless steel or aluminium. They are available with protection ratings up to IP 68 (1 bar). Electronics versions The instruments are available in different electronics versions. Apart from the two-wire electronics with 4 … 20 mA/HART, a four-wire version and two purely digital versions with Profibus PA and Foundation Fieldbus are available. Approvals The instruments are suitable for use in hazardous areas and are approved e.g. according to ATEX and IEC. The instruments also have various ship approvals such as e.g. GL, LRS or ABS.
