Field of application
The iTHERM TMS31 is a versatile, modular multipoint temperature assembly designed for temperature average detection and profiling in grain, organic bulk material storage silos and in oil, fuel storage tanks.
The device’s mechanical robustness and accurate temperature sensors offer the necessary characteristics for safe, reliable and economic product storage operations. In its standard configuration it is available with up to 20 thermocouple (TC) or RTD sensors fitted to a primary metal rope.
- Oil storage tanks 
- Bulk material silos 
Benefits
-  Easy installation and process integration thanks to a high degree of customization 
-  Flexible rope that adapts to different silos or tank operating conditions (filling, emptying, storage, …) 
-  Intrinsically safe device for use in Ex areas 
-  Highly robust design for a long product lifetime and continuous monitoring in all conditions
