Field of application
iTHERM ModuLine TM131 is a modular metric RTD or TC thermometer with protection tube or to be used with onsite thermowell. It is suitable for every application, from basic functionality to high-end performance across all industries.
For universal use across all industries: From heavy industries (Power & Energy, Chemical, Oil & Gas) to utility applications.
International certification: e.g. explosion protection according to ATEX, IECEx, CSA C/US and NEPSI.
iTEMP temperature transmitter with all common communication protocols and optional Bluetooth® connectivity.
Benefits
Modular configuration for all applications: A wide selection of components and innovations, all combined under a single order code.
Increased efficiency: Fastest response times with QuickLink thermowell and optimal thermal coupling or iTHERM QuickSens sensor design.
Enhanced safety: Reliability in demanding applications with iTHERM StrongSens and highest vibration-resistance or Dual Seal second process barrier.
Effortless handling: iTHERM QuickNeck divisible extension neck for minimized maintenance downtime.
