Field of application

The non-invasive thermometer iTHERM SurfaceLine TM611 is used across all industries to measure temperature without the risk of leakage and process disruption. The device is safe and easy to install and provides the same accuracy and response time as invasive temperature measurement. A specially designed thermal coupling element provides ideal thermal conductivity to the sensor and reduces ambient influences, resulting in superior measurement performance even compared to electronic compensation.

  • Can be used universally in all industries

  • Ideal for demanding process conditions such as high flow velocities, high process pressures, highly viscous or corrosive media, abrasion, pigging or small pipe diameters

  • Perfect for subsequent installation for measurements in existing facilities for energy and safety monitoring

Benefits

  • Measurement accuracy and response time comparable with invasive measurements

  • No process opening required, no leakage risk

  • Increased safety for personnel, plant and the environment

  • User-friendly from product selection to installation and maintenance

  • Significant cost savings: shorter development and project planning times, reduced expenses for installation, certification and inspections as well as no costs for thermowells, nozzles and flanges, weld seam inspections and pipe extensions.

  • iTEMP temperature transmitter with all standard communication protocols and optional Bluetooth® connectivity

  • International certification: e.g. explosion protection according to ATEX, IECEx, CSA and NEPSI; functional safety (SIL)
