Radiation Pyrometer

Tempsens Instruments (I) Pvt Ltd, an ISO 9001: 2008 company, offers a wide range of non contact pyrometers. Model AST A450C is a highly accurate digital two-colour Radiation Pyrometer. This device measures the temperature of an object by calculating the ratio of the energies at two different wavelength bands. Temperature measurement is not effected by parameters, affects the amount of energy reaching to pyrometer. This makes a ratio thermometer inherently more accurate. The ratio technique may eliminate, or reduce, error in temperature measurement caused by changes in emissivity, surface finish and energy absorbing materials such as water vapour between the pyrometer and the target. The pyrometer can be used in both ratio and single colour mode. These are available in temperature ranges: 600 to 1600°C and 800 to 2500°C .It has an accuracy of ±0.5% or +1°C of measured value and a fast response time of 20 msec (adjustable up to 10 sec). The parameters like, emissivity ratio, emissivity, response time, analog output sub-range are adjustable through the software supplied. AST A450C is provided with USB 2.0 connector with cable. The pyrometer can be powered through USB port. In this case no external power supply is required (+24 V DC requires for operation of analog output, laser, RS-232/RS-485 output). These pyrometers are widely used in induction heating, annealing, welding, forging, sintering, melting, rolling mills, rolling kilns, crystal growing, etc.
