Overview

The 121 series spring loaded twin threaded RTD probe is constructed with a stainless steel sheath and utilizes a spring loaded fitting to provide positive contact between the tip and the process.

Positive contact can decrease the time response of the sensor as well as provide a more consistent temperature reading.  Our crimped twin threaded hex fitting sensors are generally designed for use with thermowells, however they can be used in any application that requires the spring action. The dual threaded fitting also allows the use of a connection head.

Benefits

  • Elements: Platinum, Copper, Nickel
  • Sheath Diameter: 0.250”
  • Leadwire/Cable Options
  • 1/2” x 1/2” NPT Threaded Fitting
  • Ideal for Thermowell Applications

FAQ

Frequently Asked Questions

Q: What is an RTD?
A: An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes.  The resistance increases as the temperature of the sensor increases.  The resistance versus temperature relationship is well known and is repeatable over time. An RTD is a passive device.  It does not produce an output on its own.  External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage.
