FTR0100-01
PT100 Temperature Sensor
The PT100 Temperature Sensor from Fidar Electronics measures temperature from −50 to 250 °C with a 3-wire platinum element. It connects to a FIDAQUIRE data logger over a daisy-chained CANopen bus.
−50 to 250 °C measuring range
Platinum element with high accuracy and long-term stability
3-wire hook-up compensates for lead resistance
RJ45 output on a CANopen bus
Daisy-chains up to 64 sensors per card
Works with the FBC0232-01 card and FIDAQUIRE logger
Up to 500 m of bus at 125 kbit/s
Power and data share one cable
A PT100 is a resistance thermometer with a platinum element reading 100 Ω at 0 °C. Platinum's resistance-versus-temperature curve is unusually linear, repeatable, and near-unchanged over years, which is why PT100 is the de facto standard wherever accuracy and long-term stability decide the process — pharmaceuticals, food, oil and gas. The 3-wire connection compensates for lead resistance, so the probe can sit far from the device and right at the process point without the cable length turning into a temperature error.

Installation
Give the probe solid thermal contact with the measuring point and route its cable away from power runs — a resistive signal picks up noise easily.
