More robust sensors

Louise Smyth

Micro-Epsilon has introduced a range of protective housings for its scanCONTROL laser profile sensors and its thermoIMAGER range of infrared thermal imaging cameras. The protective housings enable the sensors and cameras to operate in extremely harsh environments, opening up both technologies to a variety of applications that were previously unsuitable.

The 26xx/29xx laser profile sensors with measuring ranges of 25, 50 and 100mm are now available with protective housing and an integrated blow-out system. If the blow-out system is fed with compressed air, dirt such as dust, swarf and chippings are removed and cleaning/maintenance intervals are extended. The protective window can be easily replaced at low cost.

A protective housing with blow-out system and water cooling is also available. This version not only protects the sensor from mechanical damage, but also from high ambient temperatures. This is achieved by using a cooling liquid fed around cooling channels/loops that are integrated to the sidewalls of the protective housing. Alternatively, if the sensor needs to operate in low ambient (outdoor) temperatures, the protective housing can be heated using a warm medium.

Micro-Epsilon’s thermoIMAGER TIM M1 thermal imager for temperature measurement of metals is now available with a range of protective housings for harsh environments. The cameras can be fitted with a stainless steel air-purging or water-cooled housing that enables the camera to operate in ambient temperatures up to 315°C. Optional protective windows are also available for the camera lens. A quick-release chassis ensures the sensor can be removed easily on site if required.
