The 2150EX is an intrinsically safe Area Velocity Flow Meter that is specifically designed and Baseefa-approved for use in Zone 0 and Zone 1 potentially explosive atmospheres under ATEX Directive 94/9/EC. The AV 2150EX smart Area Velocity probe is built on digital electronics, so the analog level is digitized in the sensor itself. The probe is also factory-calibrated for 3 meter span at different temperatures. This superior built-in calibration eliminates temperature drift in the level signal, providing long-term level stability that reduces recalibration frequency and completely eliminates span recalibration. The 2150EX is powered by the by the 2194EX network interface module for permanent, AC-powered installations, or by the 2196EX battery module for portable use. Highly efficient power management provides battery life of 6.5 weeks at a two-minute data storage interval. Standard Features Rugged, submersible enclosure is permanently sealed to meet IP68 (NEMA 4X, 6P) requirements Easy to upgrade. New operating software can be downloaded into non-volatile "flash" memory via PC connection, without affecting stored program and data, and without removing the 2150EX from the hazardous area. Chemically resistant. The epoxy-encapsulated sensor withstands tough applications. Rollover memory with variable rate data storage, lets you change the data storage interval when programmed conditions occur. Pressure transducer venting system automatically compensates for changes in atmospheric pressure to maintain accuracy Quick connect area velocity sensor can be easily removed and interchanged in the field with no recalibration.
