For temperature measurements from -50 to 1600°C, the CSlaser IR thermometer from Optris includes two targeting lasers. The laser beams follow the infrared optical path precisely and mark the real spot size accurately from any distance, avoiding faulty measurements. The smallest spot is 0.5 mm (2M model), achieved at the crossing point of the two beams at 150 mm. Various focal point versions are available to meet different requirements. The thermometer is initially offered with two different spectral ranges. Model LT with 50:1 optical resolution is for universal measurement tasks up to 975°C, where as the 2M measures up to 1600°C and has 300:1 optical resolution. The short measuring wave length of 1.6 µm reduces temperature reading errors on surfaces with low or unknown emissivity or with variable emissivity. In addition to the two-wire 4-20 mA current loop analog interface, used industry-wide, the device offers a USB interface. Besides temperature recording by integrating the sensor into the CompactConnect software, a complete programming and remote setup can be can be accomplished. Operating from 5 to 28 V, the thermometer features short-circuit and reverse polarity protection on terminal connections. The emissivity can be adjusted either directly on the unit or by software. The additional alarm output (open collector, 0-30V, 500mA) is a feature seldom found on two wire sensors. The sensor operates at ambient temperature up to 85°C without cooling and the automatic laser switches off at 50°C. Optional cooling accessories are available for a problem-free operation at higher ambient temperatures.
