New inline infrared sensors measure temperature of metals and composites from 50°C up to 1800°C

Tuesday, March 24th, 2009

Visitors to Micro-Epsilon’s stand (no. 58) at this year’s MAINTEC 2009 exhibition (17-19 March 2009) were able to see a demonstration of the company’s new thermoMETER CT laser range of infrared non-contact temperature sensors. These sensors are ideal for measuring the temperature of metals, ceramics, composites and secondary metal processing application, from 50°C up to 1,800°C.
The Micro-Epsilon thermoMETER CT laser M3 is an infrared, inline (fixed) temperature sensor that measures at a short wavelength of 2.3µm for all temperature measurements between 50°C and 600°C. This sensor has the lowest unit price of any 2-3μm-wavelength sensor currently in the marketplace – typically 60% of the cost of currently available sensors.
With a start temperature of 50°C, the thermoMETER CT laser M3 fulfills the demands of end users who need to measure the temperature of metals, ceramics and 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, in combination with excellent optical resolution (100:1), minimum spot size (0.7mm), and favourable price/performance ratio, results in a sensor that 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. Fast signal processing and quantum detector enable fast response times of just 1ms.
For higher process temperatures from 250°C up to 1,800°C, Micro-Epsilon’s new thermoMETER CT laser M1/M2 temperature sensors are ideal and can be used to measure the temperature of metals, ceramics and composites. Like the M3, the M1/M2 sensors have double precision laser sighting, but benefit from a 300:1 optical resolution and a minimum spot size of 0.45mm. Sensor response times are from 1ms.
The thermoMETER CT laser M1/M2 can be used in ambient temperatures up to 85°C without any cooling required and has an automatic laser switch off at 50°C. The sensor measures at very short wavelengths (1.0-1.6μm), which minimises temperature measurement errors on surfaces with either low or unknown emissivity.
A range of accessories and optional extras are available for the CT laser range, which protect the sensor in harsh operating environments. These include air purging accessories, K or J type thermocouples outputs and a range of integrated digital communications interfaces, including Profibus DP, CAN open, USB, RS232, RS485 and Ethernet.
