The following is a comparison of the fiber used to make probes and a few basic probe specifications for outside diameter and Immersion Time Constant.

The above picture shows actual photographs of the fiber embed in a case that compares the fiber used to make probes with a few basic probe specifications, including outside diameter and Immersion Time Constant.

Immersion Time Constant or Tao

What Is Thermal Time Constant?

The thermal time constant (often symbolized as τ) is the time it takes for a temperature sensor to respond to 63.2% of a sudden temperature change.
 
Conceptually:
  • If the ambient temperature suddenly changes from T₁ to T₂,
  • The sensor output will reach T₁ + 0.632×(T₂ − T₁) after time τ.
This comes from the exponential behavior of heat transfer:
 
Why It Matters in Fiber Optic Temperature Sensors
 
Fiber optic sensors, such as OSENSA’s work in fast-changing environments (e.g., transformersmedical ablationRF heating, etc.). In these cases:
 
  • low thermal time constant = fast response, which is crucial for detecting rapid thermal transients.
  • high TTC would miss or smooth out fast changes, leading to inaccurate readings.

Trade-offs

Design Factor                    Effect on Time Constant
Smaller thermal massFaster (lower τ)
Direct fiber exposure Faster
Protective sheathingSlower (but more robust)
Good thermal conductivity   Faster
Low heat transfer (e.g., air)    Slower

Correct Understanding:

  • The time constant does not indicate full temperature change.
  • It is the time needed to reach 63.2% of the total change.
Exponential Rule of Thumb:
  • After  → 63.2% of the change
  • After  → ~86.5%
  • After  → ~95%
  • After  → ~99.3% (effectively complete)
So, the full response takes multiple time constants (like 5x the thermal time constant), not just one.
 
Why This Matters:
  • Underestimating the actual time to stabilize can lead to false assumptions about sensor performance and response accuracy, especially in fast-changing or safety-critical systems.

FTX Temperature Transmitters

The Osensa Fiber Optic signal conditioner offers exceptional value combined with industry leading speed and accuracy. Whether your application requires one, two, or three sensing channels, the + transmitter is ideally suited for demanding research applications in MRI, microwave, and high electro-magnetic field environments. It can read optical sensors with tip diameters as small as 140 microns over distances up to 50 meters. It connects quickly to your personal computer with a standard USB cable to provide real-time temperature trending and data logging with the optional OSENSA View Pro software or LabView VI. The Optional  4-20mA analog outputs have 16 bit resolution with configurable alarms for easy connection to a PLC, temperature controller, solid state relay, or digital display. Multiple signal conditioners can be connected to a USB Port on the USB Base. Additional Groups of 10 can be used by adding USB Bases and USB Bases. Power can come connector mounted to the DIN rail  or to side mount contacts. The computer connection can be with the small USB connector on the top or bottom mounted MODBUS. Temperature transmitter come in different numbers of channels, gains, resolutions and optical paths. Higher gain transmitters may be required for systems with a number of different interconnects due to Optical path losses.

Examples:

FTX-100 – Single Channel

FTX-200 – Dual Channel

FTX-300 – 3 Channel

There are HT version for high temperature probes above 700C

Extension Cables

The Fiber Optic Extension Cables are more durable than probes and thicker. They are easier to wind, more durable  and harder to break. Extension Cables for MRI are usually used from the foot of the scanner table to the control room.

EXT is for Extension Cable, 400 is for Cable Style , others are available. Cable Lengths are specified in meters 10M is for 10 meters, 12M would be for meters, Cables are cut to length. Most Extension Cables for MRI Scanners are 10-14 meters long depending on the scanner and control room location.

STM is non Magnetic ST Connector especially for MRI. HFBR is totally non magnetic for use in Head Coils or Ultra Low Field MRI. ST is a metal connector for use outside of the Magnetic field environment.
