The KTW, WRAS, NSF, the ACS And a variety of process control systems connected to the communication interface: ? Standard HART interface ? Promag 50: the PROFIBUS-PA ? Promag 53: PROFIBUS-PA/-DP, FF Advantage Electromagnetic flow measurement systems to provide cost-effective flow measurement, high accuracy, wide measurement range. The Proline transmitter including: ? Modular structure and operational concepts to improve efficiency ? Electrode cleaning software selectable ? A unified mode of operation Promag sensors: ? Pressure loss ? Is not sensitive to vibration ? Installation and debugging of simple Proline Promag 50/53 W Function and system design The measurement principle of Faraday's law of electromagnetic induction to prove that a conductor in a magnetic field sports the sensor generates an electric potential. Electromagnetic measuring principle, the fluid Is the conductor in motion. EMF and relative to the flow rate is proportional to the two measuring electrodes detected, then the transmitter will zoom the pipe cross-sectional area to calculate the volume flow. Constant magnetic field switched direct current of alternating polarity. Ue = B? L? V Q = A? V Ue = EMF B = magnetic field strength L = the distance between electrodes v = flow velocity Q = volume flow A = pipe cross-section I = current intensity The measuring system measuring system consists of a transmitter and a sensor. There are two models available: ? Integration type: transmitter and sensor form an integral mechanical unit. ? Separation type: transmitter and sensor are installed separately. Transmitter: ? Promag 50 (key operation, two-line backlit display) ? Promag 53 (photosensitive key operation, no need to open the shell, four-line backlit display) Sensor: ? Promag W (DN 25 ... 2000) 2, Endress + Hause Measured variables Measuring range Turndown ratio Input signal Output signal Input variables Velocity (proportional to the EMF) v = 0.01 ... 10m / s, the specified measurement accuracy > 1000:1 State input: U = 3 ... 30V DC, R = 5kiΩ, electrical isolation Can be set: the cumulative amount of reset, measured value suppression, fault reset Input state, with PROFIBUS DP and MODBUS RS 485: U = 3 ... 30 VDC, Ri = 3k Ω, the level of electrical isolation switch: 3 ... 30VDC with polarity Can be set: the cumulative amount of reset, measured value suppression, the reset of fault information, batch start / stop (optional), volume accumulated reset (Optional) Current input (only Promag 53): Active / passive selectable, electrical isolation, the full scale value selectable, resolution: 3 μA Temperature coefficient: 0.005% or / ° C (or = of reading) Active: 4 ... 20 mA, Ri ≤ 150Ω, Uout = 24 VDC, the resistance to current short-circuit passive: 0/4...20mA, Ri ≤ 150Ω Umax, = 30 VDC, Output variables Promag 50 Current output: active / passive selectable, electrically isolated, time constant selectable (0.01 ... 100s), the full scale value selectable, temperature coefficient: 0.005% or / ° C, resolution: 0.5 μA ?
