The Raytek MID series of infrared thermometers provides a low-cost sensing option for installation requirements where large sensors are impractical or where multiple sensors are required to ensure uniform temperature measurement along a production line.
The MID consists of a miniature, stainless steel sensing head and separate compact electronics with a five digit backlit LCD interface for simple set-up. Advanced digital communication options provide performance similar to larger, more expensive temperature monitoring devices. For high temperature environments there is the MIH unit whose head and cable can withstand 180°C ambient temperatures.
Available with either 20:1, 10:1 or 2:1 optics, the Raytek MID provides 1% accuracy across a broad temperature range from -40t o 1200°C with a response time of 150 msec. The extremely small infrared sensing head is housed in a rugged stainless steel enclosure to ensure long-term performance, even in harsh production environments. Signal processing features, including emissivity, peak/valley hold and averaging, are easily adjustable on the LCD user interface. A 5-volt alarm signal is triggered when the pre-set target temperature or sensor head ambient temperature is exceeded. Windows-based DataTemp MulitDrop software allows technicians to program remote sensors, collect, organise and display temperature information on a PC, as well as to print temperature vs time in practical graphs and tables.
Raytek also has a solution for thermocouple replacement using a standard 0-5 VDC output with a temperature response of 150 msec and range up to 500°C. The compact Raytek CM unit has been designed to replace contact thermocouples with an infrared non-contact device.
Similar in size to an 18 vmm proximity switch, the device gives a fast response and accurate type J or K thermocouple or 0-5 VDC output that can be sent to the existing indication or control system. The unit has a 13:1 optical ratio and a temperature range up to 500°C, making it suitable for most machine applications. The unit also has a built in programmable alarm output for operation as a standalone non-contact temperature switch.
