New low cost thermal imager

Article Type: New products From: Sensor Review, Volume 29, Issue 3

Micro-Epsilon’s has launched thermoMETER CT laser 3 M. This infrared temperature sensor measures at a short wavelength of 2.3 μm for all temperature measurements between 50 and 600°C. However, probably the most significant breakthrough with this product is that it has the lowest unit price of any 2-3μm-wavelength sensor in the marketplace – typically 50 percent of the cost of currently available sensors.

With a start temperature of 50°C the new sensor fulfills the demands being made by many end-users who need to measure the temperature of metals or composites while processing at room temperature. The short wavelength also enables measurements to be taken through glass or transparent plastic windows, a common task in the latest laser welding or lighting systems.

The sensor’s precision double laser sighting, coupled with its excellent optical resolution (100:1), minimum spot size of 0.7 mm, and favourable price/performance ratio, mean the device is ideal for measuring in the metal processing and metal components industry at temperatures up to 600°C.

The double laser sighting system has two laser beams, which precisely follow the infrared optical path, marking at any distance the real spot size. Most common pyrometers use a central laser beam, through-lens sighting system or video sighting, which simply mark the centre and estimate the spot size.
