Technical Information
RTD TH11 and TH12
General purpose RTD with terminal head or conductor extension
lead wires for process and laboratory applications
Areas of application
The TH11 and TH12 temperature sensors are RTD's
designed for use in the process industry or factory
automation type of environment. They are made up
of a measurement probe with a RTD, insulation and
sheath.
Among other applications the sensors can be used on:
• Heat exchangers
• Power & recovery area
• Carbon regeneration furnace
• Dryers
• Flue Gas
• Compressor stations
• Process reactors
Head Transmitters
Instead of directly wiring your temperature sensors to
your control system, use transmitters to reduce
wiring and maintenance costs while increasing
measurement accuracy.
