Supported Applications
The Omega TFPS Series Thin Film Point Sensitive Thermocouple Sensor is designed for accurate point temperature sensing and fast response in non-invasive applications. The series supports installation on surfaces where flexible thermal ribbons are required, including aerospace, medical, and industrial devices.
- Aerospace
- Medical devices
- Industrial equipment surface monitoring
Operating Conditions & Performance
The TFPS-TC-Series utilizes thin-film technology to achieve rapid thermal response. The documented operating temperature range for the thermocouple variant (TFPS-TC-P4) is -200 to 220°C (-328 to 392°F). Time constants vary by model configuration, with TFPS-TC-P4 models listed at 0.6 sec.
- Temperature Range: -200 to 220°C (-328 to 392°F)
- Response Time (Time Constant): 0.6 sec for TFPS-TC-P4
Configuration Options
The series offers configurable options across sensor elements, insulation materials, lead wire specifications, and mounting methods.
Sensor Elements & Accuracy
While the broader Thermal Ribbon family includes RTD and Thermistor options, the TFPS-TC-Series specifically supports Type J, K, and T thermocouples with the following accuracy:
- Type “J” thermocouple: ±2.2°C or 0.75% of reading, whichever is greater
- Type “K” thermocouple: ±2.2°C or 0.75% of reading, whichever is greater
- Type “T” thermocouple: ±1.0°C or 0.75% of reading, whichever is greater
Insulation & Construction
Sensors feature polyimide insulation and are available with waterproof constructions suitable for continuous immersion.
- Insulation Material: Polyimide (TFPS-TC-P4)
- Lead Wire Insulation Options: PFA or polyimide insulated, AWG 24
Mounting & Configuration
The series supports surface mounting via pressure-sensitive adhesive (PSA) or without adhesive. Lead lengths are configurable in specific increments.
- Adhesive Backing: With (-P suffix) or Without (No suffix)
- Lead Lengths Available: 12, 36, 40, 120, 144, 240 inches
- Wire Configuration: Always “2-wire” for thermocouple models; no code needed in model number.
Key Product Differences
The TFPS-TC-Series is distinguished from other Thermal Ribbon families by its use of thin-film thermocouple elements (J, K, T) rather than RTD or Thermistor sensors. The physical dimensions for the TFPS-TC-P4 model are 0.75 x 0.75 x 0.065" (19.1 x 19.1 x 1.7 mm). Model numbers follow the format: TFPS-[Model]-[Sensor Type]-[Element]-[Number of Wires]-[Cable Insulation]-[Lead Length]-[Adhesive Backing].

Not quite what I needed
I acquired this thermocouple for use in a weekly QC procedure that requires temperature verification of four different surfaces. The insulation of the lead wire is thicker than I expected and the self-adhesive substantially lost its effectiveness after the first application/removal iteration -- I estimate that ~25% of the adhesive remained on the surface after the probe was removed the first time, and I stopped using this probe thereafter. I suspect that this probe is suitable for a variety of applications, but based on my brief experience, I would not recommend it for anything that requires removal of the probe after initial application.

Are the film thermocouples reusable?
Thanks for your question! The thermocouple itself is reusable although the adhesive will lose it's properties if it placed and removed repeatably.
