Technical Information
TH53, TH54 and TH55
Thermocouple assemblies in thermowells with
spring loaded insert and enclosure for process
industry
Application
The TH53, TH54 and TH55 temperature sensors are thermocouple assemblies
installed in thermowells and designed for use in all types of process industries,
including heavy industries, due to their rugged design. They are made up of a
magnesium oxide insulated thermocouple as a measurement probe and a thermowell
made of barstock material.
The sensor assemblies can be used in process industries such as:
• Chemicals
• Petrochemicals
• Power plants
• Refineries
• Offshore platforms
Head transmitter
All Endress+Hauser transmitters are available with enhanced accuracy and reliability
compared to directly wired sensors. 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 Fieldbus™ protocol for
highest reliability in harsh industrial environments. Backlit display with large
measured value, bargraph and fault condition indication for ease of reading.
Your benefits
• 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.
