The module Pro-PT100 has 4 or 8 inputs for connecting platinum temperature
sensors of the type Pt 100. The maximum possible measurement range is
-200°C…+266°C, depending on the temperature sensor (see the data sheets
of the manufacturers, e.g. Betatherm, Ephy-Mess, Heraeus, Jomo, Omega,
Sensycon, etc.).
The amplifier outputs are connected to a LEMO-socket via multiplexer. The
output must be connected to an additional analog input module. The multi-
plexer can be set by an
ADbasic
instruction.
Measurements are done with 2, 3 or 4 wire technique (input circuit see
). Measuring method, zero point and gain are set via jumpers and trimmers
on the circuit board (
).
The measuring methods and the wiring between senso and Pro-PT100 mod-
ule is described on
Fig. 282 – Pro-PT100-x Rev. A: Block diagram
A conversion table is available for the conversion of the temperature values
into the corresponding integer values. You will find the conversion table in the
ADbasic
online help, topic "hardware information".
