ECHOTEL 915 series 2 Wire, current shift Ultrasonic level switch DESCRIPTION Echotel 915 series ultrasonic level controls are 2 wire (24 V DC) integral units which utilize pulsed wave technology to detect high or low level alarm in a broad range of viscous to light liquids. The 915 series has protected electronics, and its high frequency signal prevents the unit from picking up noise from surrounding equipment such as engines, pumps etc... Compact and universal level switch FEATURES No calibration. 2-Wire loop powered intrinsically safe design. Continuous selftest with separate error signal. Metal and plastic transducers. High or low level detection - field selectable. High pressure / temperature ratings: - metal transducers: max 103 bar @ +150 C - Kynar (PVDF) transducers: max 19 bar / max +120 C. Suited for SIL 1, 2 and 3 loops (full FMEDA report by exida available) Threaded Echotel 915 with Kynar transducer SAFETY INTEGRITY LEVEL APPLICATIONS LIQUIDS: Any liquids with a viscosity < 10.000 cp. VESSELS: Any mounting position. PROCESS CONDITIONS: Unaffected by - shifting dielectric, density, or PH - presence of foam, turbulence, visible vapors - fast drain/fill rates - transducer coating and air bubbles - vacuum conditions.

PRINCIPLE OF OPERATION The Echotel 915 operates on a two crystal pulsed or transmit-receive principle which applies a high frequency electronic burst to the transmit crystal. The signal is then converted into ultrasonic energy and transmitted across the sensing gap toward the receiver crystal. When there is air in the gap, the high frequency ultrasonic energy will be attenuated, thereby not allowing the energy to be received. When there is liquid in the gap, the ultrasonic energy will propagate across the gap and the current shift output will indicate a reception of the signal. ma Normal Alarm T R T R Error signal Normal operation Error Air/Gas Dry gap Liquid Wet gap MOUNTING Ambient temperature: -40 C (-40 F) to +70 C (+160 F) Filling line Hi alarm Lo alarm Hi alarm Max pressure: metal transducer: 103 bar (1500 PSIG) Kynar transducer: 19 bar (275 PSIG) Lo alarm Max temp: metal transducer: +150 C (+300 F) Kynar transducer: +120 C (+250 F) Min temp: -40 C (-40 F) Pump protection Pump PERFORMANCE SPECIFICATIONS Description Specification Response time 0,15 s typical Repeatability ±2 mm (0.078") Ambient Temperature -40 C up to +70 C (-40 F to +160 F) Humidity 0-99 %, non condensing Electromagnetic Compatibility Meets CE requirements (EN 61000-6-4, EN 61000-6-2) and NAMUR NE 21 2
