Field of application
Specially designed for applications where small size of the probe and light weight are crucial. The TMS21 can be highly customized due to its versatility. It can monitor the temperature on a very high number of points along a line just by using one process connection. It is composed of several low diameters thermocouples protected by one overall primary tube thermowell. Two different product configurations are available, with or without flexible upper thermowell-hose (for axial centering).
