Pyrometers CTratio series

Ratio pyrometry has been the preferred technology in the metal processing industries due in no small part to its ability to deliver accurate temperature measurements on lower emissivity surfaces in conditions that would compromise accuracy with single wavelength pyrometers. Steam, dust and vapors are realities in most metal processing environments. Infrared windows that also attenuate the IR signal emitted from metal targets are also common when measuring temperatures of metal parts inside chambers. In our testing, we have been able to simulate these conditions and validate temperature measurement accuracy even when the infrared signal is attenuated up to 90% by using the two color ratio radiometric technology deployed in the CTratio Series. The same results are achieved when the object to be measured would not be properly resolved (too small or far away from sensor) by a single wavelength sensor.

In addition to measurement accuracy, the CTratio Series is also the best solution when the sensor or the fiber optic cable connecting to the electronics module needs to be deployed in hot ambient conditions without the use of water cooling accessories. The standard CTratio sensor head and fiber optic can withstand 200 °C (392 °F) without a water cooling accessory. A special high temperature fiber optic cable and sensing head option is available at an affordable price that equips the CTratio to deliver accurate temperature measurements in environments up to 315 °C (599 °F).
