iTHERM MultiSens Slim TMS21
Multipoint thermometer
Low-invasive, flexible TC temperature profile solution for petrochemical and chemical applications
Benefits
Large number of measuring points with a small diameter
Low-invasive temperature profile probe
Easy installation and wiring
Application areas
Designed for applications where small probe dimensions and low weight are required. The TMS21 is versatile and can be highly customized. It monitors the temperature at a large number of points along a production line using just one process connection. It consists of several small-diameter thermocouples protected by one monolithic primary tube thermowell. Two different product configurations are available, with or without a flexible upper thermowell (for axial centering).
