TPHASE

TPHASE achieves a double measurement of temperature:

• averaged measurement of very small variations of the temperature (0.01 K/min) along an optical fiber ranging from a few meters to several kilometers within 1 second of integration time.
  While conventional sensors detect only the temperature variation in their immediate environment, TPhase allows for linear measurement along the fiber following a patented principle.
• localized measurements of the absolute temperature in several points distributed on a network and integrated in a cable communicating via a data bus interface.

TPhase measures convection or radiation heat exchanges, prevents damage due to excessive temperature variations, increases the lifetime of equipments and infrastructures and improves the comfort of users.
