Robust wide-range temperature sensing for motorsports and automotive R&D
Test & Measurement
New from Variohm EuroSensor is the Texense IRN2-C linear analogue, and digital infrared sensor offers a 4…20mA output over a standard temperature range of -30C to + 220C in a compact M12 x 34mm sub-miniature housing.
The sensor is part of a range of contact-free IR temperature sensors that satisfy the various emissivity characteristics of materials for racetrack, tyre, brake and other components used in automotive and motorsports R&D applications. Based on straightforward installation with compact and durable M12 stainless steel housings, these include voltage and analogue output devices with various target temperature ranges up to +1200C as standard. Each sensor type also caters for the optimum measurement distance. The thermopile with silicone lens technology used in the company's sensors is very robust with typical shock ratings to 500g and vibration up to 20Gpp5.
In particular, the device provides an accuracy of ±2% FS with an ambient temperature error of ± 0.5C. Sensitivity is 64µA/C, response time 50msec (0-90%) and field of view is 4:1 at 50mm.
