Field of application
Intrinsincally safe temperature sensor (RTD or TC assembly) with manufactured thermowell for use with existing thermowell. An optional head transmitter with all common communication protocols – Bluetooth® technology inclusive – and special features like iTHERM QuickNeck for tool-free, easy recalibration, vibration-resistant and fast-response sensor and thermowell technology (iTHERM StrongSens, QuickSens) as well as hazardous area approvals ensure enhanced measurement accuracy and reliability.
Universal range of application
Measuring range: –200 to +1.100 °C (–328 to +2.012 °F)
Pressure range up to 100 bar (1450 psi)
Degree of protection: up to IP 68
Vibration-resistant sensor elements up to 60g
Improved ease of maintenance (sensor replacement without process shutdown), easy and safe recalibration of the measuring point
Benefits
-
Second process barrier with failure indication offering valuable health status information
-
iTHERM QuickSens: fastest response times 1.5 s for optimum process control
-
iTHERM StrongSens: unsurpassed vibration resistance (> 60g) for ultimate plant safety
-
iTHERM QuickNeck: cost and time savings thanks to simple, tool-free recalibration
Bluetooth® connectivity (optional)
-
International certification: explosion protection according to ATEX, IECEx, CSA C/US and NEPSI
