Inline infrared temperature sensors measure to 1450degC

These new thermoMETER CTLaserCOMBUSTION non-contact, inline (fixed) infrared sensors can measure target temperatures through flames and temperatures of combustible gases from +200degC up to +1450degC. The thermoMETER CTLaserCOMBUSTION series comprises three models: the C2, C4 and C6.

thermoMETER CTLaserCOMBUSTION C2

With a detector wavelength of 4.24um, this sensor is designed to measure the temperature of flame gases containing CO2. Typical applications include flame gases in the burning of waste products or rubbish, combustion chambers and processes inside chemical reactors.

thermoMETER CTLaserCOMBUSTION C4

This sensor is for measuring the temperature of workpieces or objects through flames. The detector wavelength of 3.9um enables the sensor to 'see through' the flame, as at this wavelength the combustion gases are transmissive to the detector. In this way, users can safely monitor the temperature of the workpiece inside a chemical reactor, industrial oven or furnace, or observe the brick temperature in combustion chambers.

thermoMETER CTLaserCOMBUSTION C6

With a detector wavelength of 4.64um, this sensor is for measuring the temperature of flame gases containing carbon monoxide (CO). Application examples include chemical reactors, burning of waste and combustion chambers.

For all temperature measurements between 200 °degC and 1450degC, the three sensors measure at short wavelengths (3.9um-4.64um), which minimises temperature measurement errors on surfaces with either low or unknown emissivity. The sensors have a precision double laser sighting system, combined with an optical resolution of 45:1 and with selectable close focus optics and a minimum spot size of 1.6mm - all of which offers an attractive price/performance ratio.

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 10ms.

Micro-Epsilon's thermoMETER CTLaserCOMBUSTION sesnors are protected to IP65 and can be used in ambient temperatures from -20 to +85degC without any cooling required. The sensors have an automatic laser switch off at 50degC. A range of accessories and optional extras is available, which help to protect the sensor in harsh operating environments. These include Furnace Wall Mounts, air and water cooling jackets and sighting tubes. The sensors are offered with analogue outputs (0-10V or 4-20mA), K or J type thermocouples outputs as standard, with a range of integrated digital communications interfaces, including Profibus DP, CANopen, USB, RS232, RS485 and Ethernet available as options.

Glenn Wedgbrow, Sales Manager at Micro-Epsilon UK, comments: "To be able to measure the real target temperature whilst still in the flame furnace is extremely valuable to the user, where having the right material temperature is crucial in achieving the correct properties of the material for further steps in the manufacturing process. It also offers the ability for operators to control the furnace more efficiently."
