PX455 with Pt100 temperature measurement
With the PX455 measurement module, temperatures can
be measured with an uncertainty of +/-1°C without an
external preamplifier. A 100 ohm precision resistor
(R_comp) with a maximum tolerance of 0.1% is added to
a Pt100 resistor to make a half bridge circuit. The PMX
calculated channel "Pt100 on PX455" converts the meas
ured bridge unbalance to degrees Celsius and performs a
corrective calculation appropriate to the sensor cable be
ing used (R_wire).
Important
Good heat dissipation is essential to keep the measure
ment error caused by the self heating of the Pt100 as low
as possible! This can be done, for example, by mounting
it on a metallic body.
