Probes And Sensors
Temperature probes and reference sensors are the part of a measurement chain that actually touches the process, and they set the accuracy ceiling for everything downstream.
Fluke Calibration, Ametek Jofra, AccuMac, Additel and Isotech cover this range, from industrial RTDs to secondary reference standards. Four-wire platinum resistance thermometers remove lead resistance from the measurement and are what you need for calibration work, while three-wire and two-wire designs are adequate for process indication. Match the sheath diameter and immersion depth to the thermowell you are using, since insufficient immersion produces a stem conduction error that no amount of instrument accuracy will correct. Confirm the connector type against your readout before ordering.
