Critical Technical Advantages
-
Dual Barrier Safety System: The TMS12 combines a robust primary thermowell with a secondary diagnostic chamber. In the rare event of a primary seal breach, the diagnostic chamber contains the process medium, preventing environmental release and protecting personnel.
-
Integrated Leak Detection: The diagnostic chamber can be equipped with monitoring equipment to detect the presence of process fluid or pressure changes. This enables predictive maintenance and immediate alerting through the control system before a critical safety event occurs.
-
Maintenance Without Downtime: Because the individual RTD or TC inserts are housed within the primary thermowell, they can be replaced or recalibrated during active process operation. This maximizes plant availability and reduces the high costs associated with process shutdowns.
-
Electronic Heat Protection: The device features on-board heat protection for the integrated electronics. This ensures that transmitters and connection components remain within safe operating temperatures, even when the assembly is mounted on vessels with extreme radiant heat.
-
Superior Mechanical Integrity: The primary thermowell is machined to withstand high flow velocities and mechanical stresses, ensuring the internal sensors are never exposed to the physical forces or corrosive nature of the process medium.
-
Full Compliance Architecture: The TMS12 is designed to meet a broad range of international safety standards, including ATEX for hazardous areas and the Pressure Equipment Directive (PED), simplifying the engineering and integration process for global projects.
