D.A.D. PT100 Temperature Sensor
How does a PT100 Sensor work?
– Based on resistance measurement principle
– Material: Platinum, resistance value 100Ω, temperature 0°C
– Resistance increases with rising temperature
– Resistance variation is a function of temperature; 0.39Ω/1°C
– Long term stability
PT100 Accuracy Classes
Standard IEC60751 defines PT100 resistance accuracy classes and corresponding tolerances. The tolerance classes for wire wound resistors used for EPIC®SENSORS are:
Class A – applies on temperature -100…+450°C
Commonly used PT100 designs are the Screw Fixed, Transparent Tube, Black PE and Screw Fixed with Ceramic Sand.
PT100 Temperature Sensor Applications:
– Solar Panels
– Switchgear Panels
– Machinery
– Boiler Plate
Overview of PT100 Advantages:
– Very stable output
– Linear and predictable
– Easy verification and recalibration
– High accuracy
– No special wire required for installation
