The miniature embedment RTD probe is a micro temperature sensor designed to be embedded into areas where space is limited.
miniature rtd probe sensors

These RTD probe sensors are commonly installed in bearings and housings of rotating machinery.  They are used to detect temperature changes at the point of contact in bearings, oil, air, water and other process control applications. The sensing element is installed in a small metal case. This allows for increased accuracy and sensitivity to temperature changes at the point of contact in bearings. These miniature sensors are easy to install where space is limited and a hole can be drilled for placement. We offer a variety of custom options for Embedment RTD probes to suit any application. Feedthroughs provide a fluid seal where the cable exits the installation. Leadwire and cable seals allow position adjustment while protecting your application from leakage. Elastomer filled cable is also available.

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.
