The EDL Roller Contact Sensor is the number one choice across industries for measuring temperatures of moving or stationary smooth, flat surfaces. We offer this style of sensor with or without the handle. Versions with replaceable bands are also available (RAB & RAH Holders).

Standard Roller Contact Sensors are designed for spot-checking and intermittent monitoring; they have a nylon block and a Stainless-Steel band. This sensor works in ambient temperatures up to 175 °C (350 °F). This ambient temperature must take into account the radiated heat from the object under test. If the ambient temperature (the anticipated radiant energy) or if the sensor is to be used for long periods of time, then contact us and we will supply the block in a high temperature material. Be aware if the ambient temperature exceeds 250 °C (500 °F), the lead wire will be changed from the standard Teflon® construction. Contact sales at [email protected] or 434.799.0807.

The standard band on the Roller Contact Sensor will withstand temperature up to 425 °C (800 °F). High temperature bands have a design limit of 650 °C (1200 °F) with some slight modification the range on the high temperature bands can be extended to 815 °C (1500 °F). Contact [email protected] or 434.799.0807 for assistance. Please note, the higher temperature bands are annealed and may wear at a more accelerated rate.

EDL's Roller Contact Surface Sensors are extremely accurate, fast, and effective on all cylindrical surfaces. Bands are durable and allow for rapid measurement response times. Bands are available in three standard sizes, 2.5", 5", and 12" to accommodate diameters from 1" to 120". These sensors are ideal for use on rotating or stationary pipes, drums, tanks, hoses, and much more.

Max. Temperature for T is 400 °C.

All EDL Surface Sensors come standard with a 32” lead with Stainless Steel overbraid.

EDL’s Metrology Laboratory will supply any sensor and instrument complete with a report of calibration that is traceable to NIST. Search CAL to order calibration. For more information contact us at [email protected].

As with all surface type sensors, Roller Contact Sensors are able to be calibrated. They can't be calibrated by immersion techniques, but rather they must be tested on a calibrated reference surface. EDL offers the Surface Transfer Standard STS line of calibrators for this purpose. Search STS or contact [email protected].

When using a Roller Contact Sensor, you don't need to use excessive force. You should only apply enough pressure on the band so it deflects and starts to curve around the object being tested.

When testing small diameter objects, make sure the object stays in the center of the band, do not push so hard that the band touches the block; this will damage the thermocouple wires on the back of the band. Always have at least 1/8" of deflection in the band.
