Endress+Hauser Proline Promag 50 - 10.1.6 Performance Characteristics

PROline Promag 50 10 Technical data
Endress+Hauser 109
Power consumption AC: <15 VA (including sensor)
DC: <15 W (including sensor)
Switch-on current:
• max. 13.5 A (< 50 ms) at 24 V DC
• max. 3 A (< 5 ms) at 260 V AC
Power supply failure Lasting min. 1 power cycle
• EEPROM saves measuring system data if power supply fails
• S-DAT: exchangeable data storage chip which stores the data of the sensor (nominal
diameter, serial number, calibration factor, zero point, etc.)
Potential equalisation see Page 56 ff.
10.1.6 Performance characteristics
Reference operating
conditions
To DIN 19200 and VDI/VDE 2641:
• Fluid temperature: +28 °C ± 2 K
• Ambient temperature: +22 °C ± 2 K
• Warm-up time: 30 minutes
Installation:
• Inlet run >10 x DN
• Outlet run > 5 x DN
• Sensor and transmitter grounded.
• Sensor centered relative to the pipe.
Maximum measured error Pulse output:
• ± 0.5% o.r. ± 1 mm/s (o.r. = of reading)
• Option: ± 0.2% o.r. ± 2 mm/s (o.r. = of reading)
Current output: plus typically ± 5 µA
Supply-voltage fluctuations have no effect within the specified range.
