Thermal change, current output
Fig. 31: Thermal change, current output
Long-term stability (according to DIN 16086 and IEC 60770-1)
Applies to digital HART interface as well as to analogue current output 4 ... 20 mA under refer-
ence conditions. Specifications refer to the set span. Turn down (TD) is the ratio nominal measuring
range/set span.
Long-term drift of the zero signal:
Ʋ For one year
Ʋ For five years
Ʋ For ten years
Ambient conditions
Ambient, storage and transport temperature
Ʋ Version with connection tube
Ʋ Version with suspension cable FEP,
PUR
Ʋ Version with suspension cable PE
Process conditions
The specifications of the pressure stage and product temperature are used as an overview. The
specifications on the type label are applicable.
Process pressure, transmitter
Ʋ with measuring ranges 0.1 bar
(1.45 psig) or 0.2 bar (2.9 psig)
Ʋ with meas. ranges from 0.4 bar
(5.8 psig)
Pressure stage, process fitting
Ʋ Threaded fitting
Ʋ Thread
Ʋ Lock fitting
Ʋ Flange 316L
Ʋ Flange GFK
Limited by the overpressure resistance of the measuring cell.
12)
Limitation by the pressure-tightness of the cable connection.
13)
Limited by the overpressure resistance of the measuring cell.
