Endress+Hauser Proline Promass 80 - Performance characteristics; Maximum measured error

10 Technical data PROline Promass 80
84 Endress+Hauser
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 is an exchangeable data storage chip with sensor specific data:
nominal diameter, serial number, calibration factor, zero point, etc.
10.1.6 Performance characteristics
Reference operating
conditions
Error limits following ISO/DIS 11631:
• 20...30 °C; 2...4 bar
• Calibration systems as per national norms
• Zero point calibrated under operating conditions
• Field density calibrated (or special density calibration)
Maximum measured error The following values refer to the pulse/frequency output.
Measured error at the current output is typically ±5
µA.
