PROline Promag 10 10 Technical data
Endress+Hauser 79
Power consumption 85...250 V AC: <12 VA (incl. sensor)
20...28 V AC: <8 VA (incl. sensor)
11...40 V DC: <6 W (incl. sensor)
Switch-on current
• Max. 3.3 A (< 5 ms) at 24 V DC
• Max 5.5 A (< 5 ms) at 28 V AC
• Max. 16 A (< 5 ms) at 250 V AC
Power supply failure Lasting min. ½ cycle frequency:
EEPROM saves measuring system data if power supply fails.

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. ± 2 mm/s (o.r. = of reading)
Current output: also typically ± 5 µA
Supply voltage fluctuations do not have any effect within the specified range.
