Sensor Technology

C-Therm's revolutionary sensors are the heart of the technology. These innovative components are available in a number of configurations and can be engineered to meet the specific needs of an application and the environment in which they will operate. C-Therm sensors precisely measure thermal conductivity values in the range of 0.035 to 100 W/m•K, as well as other thermal properties, including effusivity and diffusivity; product uniformity, consistency & homogeneity.

C-Therm sensors can be engineered to the specific needs of an application. Using thermal effusivity as a proxy, these durable, accurate instruments rapidly measure a number of thermal properties in seconds - without damaging the sample being tested.

A Unique Mode of Operation

Using interfacial reflectance to measure thermal properties, C-Therm sensors offer rapid testing, consistency, uniformity & homogeneity of a broad range of materials, from solids and powders to liquids and pastes. The modified transient plane source technique is the basis of their design, operation and accuracy. This technique was developed and patented by Mathis Instruments (now C-Therm Technologies).  The sensor actually supplies the heat, approximately 2 - 3°C, and uses the same metallic filament to measure heat reflected back by the sample. As a result, they require access to only one side of the sample – and testing, which is completed in a matter of seconds, does not damage or affect the sample.

Robust, Customized Solutions

A key advantage of C-Therm sensors is their durable construction. The current sensors employ stainless steel outer wall construction and use a FDA-approved food grade material on the sensor surface. All electronics are housed within the sensor itself, protecting these components from any contaminants that may be present in the operating environment.

C-Therm sensors can be engineered and customized to address the needs and operating conditions of a specific application.
