The 500 series point sensing RTD probe is constructed with a rigid stainless steel sheath with an element embedded into an aluminum tip.
point sensing rtd probe

The aluminum tip of the 500 series RTD probe sensor provides faster time response.  These sensors are typically designed for use in plenums and ducts within HVAC systems. They can also be utilized whenever a quick time response in a non-corrosive low pressured environment is needed.

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.
