We have observed, where temperature is being measured in bulk material or large volume air or liquid, a single point sensor isn’t effective in representing the thermal characteristics of the entire area of interest. Installing several discrete sensors can be cumbersome requiring multiple installation points.
Averaging sensors and Multi-point sensors can serve these applications extremely well. We have developed a Compendium of Averaging and Multi-Point Sensors and their Applications to provide some insight into these unique measurement situations.
Temperature is a key indicator of bearing health. For rotating equipment, reliability and predictive maintenance is an imperative to “Up-time”. This family of Bearing Sensors, available in a variety of configurations or customized to meet your specific application, will provide the confidence required for your processes.
Designs include single or dual RTD, thermocouple, 1/8″ to 1/4″ diameter, straight or bent, and a variety of process fittings.

YES! It can be as easy as measuring the resistance in a container of ice water. (you don’t need a Triple Point of Water Cell.)
We have discovered too many times that sensors are installed in systems that experience a combination of temperature cycling, over temp excursions, vibration, high flow rates and /or just left unattended for years. In many cases this is not a concern based on the requirements of the measurement. Although, if these influences exists and the expectation is to be confident that the measurement represents the actual process media temperature, periodic verification can ensure that confidence.
This paper titled: Developing a Periodic Performance Verification Program for Platinum Resistance Thermometers, will help you understand the importance, and provide some guidance on how to establish a verification approach that is right for your application.

Our Mission is Your Measurement!
We believe that any sensor will provide a measurement, although if the influences that exist in the application are not managed or planned for, that measurement may not represent the actual process temperature.

The surface mount RTD is used to obtain a temperature measurement on pipes, tanks, or other surfaces. Installation is accomplished by means of clamps, adhesives, bolts or screws and typically does not require modification of the surface to be measured. Addition of an insulating blanket over the sensor improves accuracy by shielding it from the ambient temperature.
This Application Note describes a measurement challenge where a surface mounted RTD is an effective choice.
