RTD assemblies in thermowells with spring loaded insert and enclosure for process industry

Application

The TH13, TH14 and TH15 temperature sensors are RTD assemblies installed in Thermowells and designed for use in all types of process industries, including harsh environments, due to their rugged design. The sensor is made up of a measurement probe with an insulated RTD element, sheath and a thermowell made of bar-stock material.

Among other applications the sensors can be used in process industries such as:

  • Chemicals
  • Petrochemical
  • Power plants
  • Refineries
  • Offshore platforms
Head transmitter

Instead of directly wiring your temperature sensors to your control system, use transmitters to reduce wiring and maintenance costs while increasing measurement accuracy.

Field transmitter

Temperature field transmitters with HART or FOUNDATION FieldbusTM protocol for highest reliability in harsh industrial environments. Blue backlit display with large measured value, bargraph and fault condition indication for ease of reading.

Your benefits
  • High flexibility due to modular assembly with standard terminal heads and customized immersion length
  • 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 and transmitter assembly for a complete point solution
  • All iTEMP transmitters provide long term stability ≤ 0.05 % per year
  • Fast response time with reduced/tapered tip form
Measuring Principle

These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. This temperature sensor is a temperature-sensitive platinum resistor with a resistance of 100 Ω at 0 C (32 F) and a temperature coefficient is α = 0.003851 C -1 .

There are generally two different kinds of platinum resistance thermometers:
  • Wire wound (WW): Here, a double coil of fine, high-purity platinum wire is located in a ceramic support. This is then sealed top and bottom with a ceramic protective layer. Such resistance thermometers not only facilitate very reproducible measurements but also offer good long-term stability of the resistance/temperature characteristic within temperature ranges up to 600 C (1 112 F). This type of sensor is relatively large in size and it is comparatively sensitive to vibrations.
  • Thin film platinum resistance thermometers (TF): A very thin, ultrapure platinum layer, approx. 1 μm thick, is vaporized in a vacuum on a ceramic substrate and then structured photolithographically. The platinum conductor paths formed in this way create the measuring resistance. Additional covering and passivation layers are applied and reliably protect the thin platinum layer from contamination and oxidation even at high temperatures.

The primary advantages of thin-film temperature sensors over wire wound versions are their smaller sizes and better vibration resistance. A relatively low principle-based deviation of the resistance/ temperature characteristic from the standard characteristic of IEC 60751 can frequently be observed among TF sensors at high temperatures. As a result, the tight limit values of tolerance category A as per IEC 60751 can only be observed with TF sensors at temperatures up to approx. 300 C (572 F). For this reason, thin-film sensors are generally only used for temperature measurements in ranges below 400 C (932 F).
