New IR sensors take the heat without having to cool down.
Raytek, a leading worldwide provider of infrared thermometry, has enhanced its MI Series of miniature digital non-contact infrared (IR) thermometers with the release of the Raytek MIH sensor as well as enhanced versions of the popular Raytek MID and MIC sensor models. The product innovations were introduced to address a broader range of process applications, including harsh and high-temperature environments.
The latest addition
The new Raytek MIH sensor can be installed in environments with ambient temperatures up to 180°C without the need for water or air cooling accessories, making it ideal for continuous temperature monitoring in high-temperature applications. Water and air cooling accessories not only add installation and maintenance costs, they can leak, or condensation produced by cooling can obscure the sensor’s field of view and interfere with measurement accuracy. In addition, the MIH sensor includes a Teflon coated cable to withstand exposure to harsh chemical environments.
Product enhancements
Both the Raytek MID and MIC IR sensors have been enhanced with Halogen and Silicone-free PUR cables to withstand harsh environments; The sensors also include screws that are fixed to the sensor’s box lid so they cannot be lost during installation, potentially damaging equipment or affecting product quality. A standard RS232 communication interface is available for remote PC-controlled monitoring. Both sensors also feature an optional viewing window in the lid, revealing the LED underneath and reducing the need for an external indicator for displaying temperature values. While the MID model can be installed in ambient environments up to 85°C, the MIC sensor can handle ambient environments up to 125°C, also without the need for water or air cooling. Both MIC and MIH sensors include additional calibration for increased measurement accuracy.
The cable connects the miniature sensing head to the sensor electronics housed separately
Applications
The compact size of all the Raytek MI Series sensors enables them to be seamlessly integrated into existing control equipment or OEM systems. All the sensors include an optional RS485 interface, which allows up to 32 sensors to be networked in a multidrop configuration on just two wires, reducing installation costs and facilitating the design of custom equipment. Optional Raytek DataTemp software enables easy remote sensor control and data collection.
The broad range of features and flexible hardware options of the expanded and enhanced Raytek MI Series sensors make them ideal for a wide range of applications, including thermoforming, glass, paper mills, printing, converting, paint booths, drying, and food processing.
