0

Safe monitoring of process temperatures in challenging applications e. g. in the Oil & Gas industry. The robust device with a barstock thermowell is a complete unit ready for use with various housing transmitter heads to meet the application and space requirements. The unit offers enhanced measurement accuracy and reliability. A variety of process connections, dimensions, and materials (like 316L SS and Hastelloy C276) offer flexible application possibilities.

  • FM/CSA XP Class I, Div. 1 approved temperature assemblies for maximum safety

  • One source shopping for temperature measurement solutions. World class transmitter with integrated sensor offering for heavy process industry applications

  • Remove and install straight out of the box!

  • Improved galvanic isolation on most devices (2 kV)

  • Simplified model structure: Competitively priced, offers great value. Easy to order and reorder. A single model number includes sensor, thermowell and transmitter assembly for a complete point solution

  • All iTEMP transmitters provide long term stability ≤0.05% per year

The T13 temperature sensor is a RTD assembly installed in thermowell and designed for use in harsh environments and explosive areas, due to his FM and CSA approvals.
The sensor is made up of a measurement probe with an insulated RTD element, sheath and a thermowell made of bar-stock material.

The sensor assembly can be used in process industries such as:
