Options for Semiconductor Process Tool Temperature Control (.pdf)
Traditionally, Chillers, i.e. refrigerated temperature control equipment, are viewed as the preferred choice for removing heat from process equipment or for controlling their temperature. Depending upon the application and the degree of control required, however, Heat Exchangers can represent

Non-contact Temperature Measurement and Control (.pdf)
In recent years infrared ovens and systems used to dry or heat materials in continuous web form or sheets running edge to edge have become more sophisticated by using automatic (closed loop) control systems. The temperature of the moving material is continuously measured with a non-contact

Ultrasonic Air Temperature Sensing for Automatic Climate Control - Vehicle Test (.pdf)
An ultrasonic air temperature sensor, intended to help improve automatic climate control (ACC), has been demonstrated in a vehicle. Ideally, ACC should be based on inputs correlated with thermal comfort. Current ACC systems do not measure the air temperature best correlated to thermal comfort

HVOF Process Control Using Almen and Temperature Measurement (.pdf)
The HVOF process with reduced heat effect on the substrate and therefore minimal degradation of fatigue properties is now finding wide application in fatigue critical applications. The critical parameters for process control are residual stress in the deposit and maximum substrate temperature
