FTR0100-11
Wireless PT100 Temperature Sensor
The Wireless PT100 Temperature Sensor from Fidar Electronics measures temperature from −50 to 250 °C with a 3-wire platinum element. It links over a LoRa radio with no cabling at all.
−50 to 250 °C measuring range
Platinum element with high accuracy and long-term stability
3-wire hook-up compensates for lead resistance
LoRa radio link up to 1 km line of sight
AES-128 encrypted payloads
Pairs with the FWL1600-01 LoRa card
No cabling; pairing takes seconds
Low-battery warning per node
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.
