Description

Application

The TH14 Modular RTD thermometer is designed for a wide range of demanding applications, particularly in harsh environments found in industries such as power plants, refineries, and the chemical or petrochemical sectors. This durable device features a barstock thermowell and flange connection made from SS316 or INCONEL600, along with various head transmitters, making it a comprehensive, ready-to-use solution that ensures enhanced measurement accuracy and reliability.

TH14 temperature sensors are RTD assemblies that are installed in thermowells and are specifically engineered for use in all types of process industries, including those with harsh environmental conditions. The rugged design includes a measurement probe with an insulated RTD element, a sheath, and a thermowell crafted from barstock material.

These sensor assemblies are suitable for use in process industries such as:

  • Chemical
  • Petrochemical
  • Power plants
  • Refineries
  • Offshore platforms

 


Benefits

  • High Flexibility: The modular assembly allows for standard terminal heads and customizable immersion lengths, adapting to various needs.
  • Comprehensive Solution: Offers a one-stop solution for temperature measurement with a world-class transmitter integrated with the sensor, perfect for heavy-duty process industry applications. The device is ready to use straight out of the box, with easy installation and removal.
  • Enhanced Galvanic Isolation: Most devices offer improved galvanic isolation up to 2 kV, ensuring greater safety and reliability.
  • Simplified Ordering: The streamlined model structure is competitively priced, offering excellent value. The ordering process is straightforward, with a single model number that includes both the sensor and transmitter assembly, providing a complete point solution.
  • Long-Term Stability: All iTEMP® transmitters deliver long-term stability of ≤ 0.05% per year, ensuring consistent performance.
  • Fast Response: The reduced or tapered tip form allows for quick response times.
  • Versatile Head Transmitter: Easy selection of head transmitters with options for Analog output 4 to 20 mA, HART®, PROFIBUS® PA, or FOUNDATION Fieldbus™.
