© Siemens AG 2016 Level Measurement Continuous level measurement - Ultrasonic transmitters The Probe ■ Overview ■ Configuration Parabolic mounting 4 The Probe is a short-range integrated ultrasonic level transmitter, ideal for liquids and slurries in open or closed vessels. ■ Benefits • • • • • Easy to install, program, and maintain Accurate and reliable Sanitary models available Sonic Intelligence echo processing Integral temperature compensation Flat mounting and beam angle Fill ■ Application The transducer is available in PVDF copolymer, making the device suitable for use in a wide variety of applications. The Probe is easy to install and maintain, and can be quickly removed for cleaning as required by the food, beverage and pharmaceutical industries. The reliability of the level data is based on the Sonic Intelligence echo processing algorithms. A filter discriminates between the true echo and false echoes from acoustic or electrical noises and agitator blades in motion. The ultrasonic pulse propagation time to the material and back is temperature-compensated and converted into distance for display, analog output and relay actuation. • Key Applications: chemical storage vessels, filter beds, mud pits, liquid storage vessels, food applications Pipe Rungs Seams 12° Beam angle The Probe mounting Siemens FI 01 · 2016 4/145 © Siemens AG 2016 Level Measurement Continuous level measurement - Ultrasonic transmitters The Probe ■ Technical specifications Three-wire version Two-wire version (standard) Ultrasonic level measurement Ultrasonic level measurement Mode of operation Measuring principle Article No. The Probe Short-range integrated ultrasonic level transmitter, ideal for liquids and slurries in open or closed vessels 7ML1201- Measuring range 0.25 ... 5 m (0.8 ... 16.4 ft) 0.25 ... 5 m (0.8 ... 16.4 ft) Frequency 54 kHz 54 kHz 4 ... 20 mA Proportional/ inversely proportional 750 at 24 V DC 4 ... 20 mA Proportional/ inversely proportional 600 in the loop at 24 V DC Output mA • Span • Max. load For level alarm or No fault Relay Power supply 18 ... 30 V DC, max. 0.2 A 12 ... 30 V DC, 0.1 A surge Max. power consumption 5 W (200 mA at 24 V DC) 0.75 W (25 mA at 24 V DC) Certificates and approvals CE, RCM, CSAUS/C, FM CE, RCM, CSAUS/C Accuracy Error in measurement 0.25 % of measuring range (in air) Resolution 3 mm (0.125 inch) Temperature compensation Built in PVDF copolymer, 2" NPT [(Taper), ANSI/ASME B1.20.1] PVDF copolymer, R 2" [(BSPT), EN 10226] PVDF copolymer, G 2" [(BSPP), EN ISO 228-1] PVDF copolymer, 4" Sanitary mounting Model/Approval 3-wire, 24 V DC, CE, RCM, CSA, FM 2-wire, 24 V DC, CE, RCM, CSA E F G J E F Order code Further designs Please add "-Z" to Article No. and specify Order code(s).
