Performance Under Rated Conditions – General for all Models

Parameter	Description
Output (two-wire)	Analog 4 to 20 mA or digital communications DE mode. Options available for
	FOUNDATION Fieldbus and HART protocol.
Supply Voltage Effect	±0.005% of span per volt.
Damping Time Constant	Adjustable from 0 to 32 seconds digital damping.
RFI Protection (Standard)	Negligible (20 to 1000 MHz at 30 volts per meter).
CE Conformity (Europe)	89/336/EEC, Electromagnetic Compatibility (EMC) Directive.
NAMUR NE 43 Compliance	Transmitter failure information is generated when the measuring information is invalid or
Option	no longer present. Failure information is transmitted as a current signal but outside the
	normal 4-20 mA measurement signal level. Transmitter failure values are: ≤ 3.6 mA and
	≥ 21.0 mA. The normal signal range is ≥ 3.8 mA and ≤ 20.5 mA.
SIL 2/3 Compliance	SIL certified to IEC 61508 for non-redundant use in SIL 2 related Safety Systems
	(single use) and for redundant (multiple) use in SIL 3 Safety Systems through
	TÜV Nord Sys Tec GmbH & Co. KG under the following standards: IEC61508-1: 1998;
	IEC 61508-2: 2000; IEC61508-3: 1998.
