Field of application
Intrinsincally safe temperature sensor (RTD / TC assembly) with manufactured thermowell or 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
