Maximum measured error

Endress+Hauser
The device can be ordered with integrated overvoltage protection for several approvals:
Order code for "Accessory mounted", option NA "overvoltage protection"
Input voltage range
Resistance per channel
DC sparkover voltage
Trip surge voltage
Capacitance at 1 MHz
Nominal discharge current
(8/20 ms)
Temperature range
1)
The voltage is reduced by the amount of the internal resistance I
Depending on the temperature class, restrictions apply to the ambient temperature for device versions
with overvoltage protection .
