Supported Applications
The Omega TFPS-Th Series Thin Film Point Sensitive Thermistor Sensor is designed for accurate point temperature sensing in non-invasive applications. The series supports installation on surfaces where fast response and sensitivity to small temperature changes are required, including aerospace, medical, and industrial devices.
Operating Conditions & Performance
The TFPS-Th Series operates within a process temperature range of -50 to 125°C (-58 to 257°F). The sensing element utilizes an NTC thermistor with resistance values of either 50kΩ or 10kΩ, both specified at ±1% accuracy at 25°C. Response times vary by insulation type: models with polyimide and elastomer coating (TFPS-Th-PE) exhibit a time constant of 0.8 sec., while silicone rubber/foil backed versions (TFPS-Th-SRE) show a time constant of 1.3 sec.
Configuration Options
The series offers configurable options for insulation, lead wire materials, lengths, and mounting methods to accommodate specific installation needs.
- Sensor Elements: Available as NTC thermistor 50kΩ ±1% at 25°C (TF) or NTC thermistor 10kΩ ±1% at 25°C (TK).
- Insulation Types: Polyimide with elastomer coating for TFPS-Th-PE models; silicone rubber/foil backing is available on specific configurations.
- Lead Wire Options: AWG 26 lead wires are standard, insulated with either PFA (suffix T) or Silicone Rubber (suffix R).
- Cable Lengths: Configurable lengths include 12, 36, 40, and up to 120 inches. Note that models PE and SRE have a maximum lead length of 60".
- Mounting: Sensors feature surface or pressure-sensitive adhesive (PSA) backing for quick mounting; the suffix "-P" indicates inclusion of adhesive, while no suffix denotes without adhesive.
- Electrical Connection: Available as lead wire versions. For thermistor models in this series, the number of wires is always 2-wire.
Dimensions by Model Type
- TFPS-Th-PE-*: 0.20 x 0.47 x 0.079" (5.0 x 12.0 x 2.0 mm)
- TFPS-Th-SRE-*: 0.20 x 0.60 x 0.118" (5.0 x 15.2 x 3.0 mm)
Key Product Differences
The TFPS-Th Series is distinguished from other Thermal Ribbon families by its use of NTC thermistor elements rather than RTD or Thermocouple sensors. Within the series, variations are defined primarily by insulation material and resulting physical dimensions: the PE variant uses polyimide with an elastomer coating for a thinner profile (0.079" / 2.0 mm), whereas the SRE variant utilizes silicone rubber/foil backing, resulting in greater thickness (0.118" / 3.0 mm) and a longer time constant.

Do you have the b value or type (2, 3) for these thermistors?
Thank you for your inquiry. The Steinhart-Hart Equation for this sensor is:
1/T=A+B ln(R)+C[ln(R) ]^2+D[ln(R) ]^3
Where T is temperature in Kelvin,
A = 7.4450E-4
B = 3.4717E-4
C = -1.0790E-5
D = 4.1845E-7
