TMS12 iTHERM TMS12 MultiSens Linear Multipoint
Field of application
The iTHERM TMS12 MultiSens Linear multipoint thermometer for oil & gas and chemical applications can be customized for various scenarios in compliance with the highest safety standards. It increases process safety by creating detailed linear temperature profiles and features a diagnostic chamber to contain and monitor leakages through the primary seals. Easy process integration reduces installation time and thus maximizes plant availability.
