Resistance Temperature Detectors (RTD)

Resistance Temperature Detectors (RTD)

as the name implies, are sensors used to measure temperature by correlating the resistance of the RTD element with temperature.

RTDs are relatively immune to electrical noise and therefore well suited for temperature measurement in industrial environments, especially around motors, generators and other high voltage equipment.

Type

Pt 100, 200, 500, 1000,
copper 50,53. etc

Element size (MI)

Wire wound ceramic encapsulated
Wire wound Glass encapsulated
Thin film ceramic encapsulated

Connection

2, 3, 4 wire

Accuracy
Class A, B 1/2, 1/3, 1/5, 1/10 DIN
