Averaging connection or differentiating
connection (of 2 channels)
1 resistance thermometer in two, three or
four-wire circuit
Averaging connection between two re-
sistance thermometers in two-wire circuit,
parameterizable equivalent value behavior
(e. g. the value of the other channel is output
when the channel is defective)
Differentiating connection between two resi-
stance thermometers in two-wire circuit, diffe-
rence is parameterizable (e.g. channel 2 –
channel 1).
Series or parallel circuiting of several
resistance thermometers in two-wire circuit,
e.g. to adapt other transmitter types, is
implemented as an additional function. This
gives a scaling factor.
Line resistance parameterizable ≤5 % of the
measuring range
No adjustment necessary. The line
resistances must be equal between the
respective sensor connection and the
appropriate connection on the transmitter.
No adjustment necessary.
