A temperature detection module for detecting a temperature of a measurement target is provided. The temperature detection module includes a temperature sensor, and a holder for holding the temperature sensor such that movement is possible in a separation and contact direction in which the temperature sensor is separated from and brought into contact with the measurement target. The temperature sensor includes a sensor main body portion in which a temperature detection element is accommodated, and a spring portion that is integrally provided on the sensor main body portion. The spring portion is of a type that expands and contracts only in a single direction, and expands and contracts only in the separation and contact direction. The spring portion is attached to the holder and biases the temperature sensor such that a detection surface comes into contact with the measurement target.

A sensor system comprises a first sensor, a second sensor, a high pass filter, and a summation unit. The first sensor senses an environmental parameter and outputs a first electronic signal with a response having a first time constant. The second sensor senses the environmental parameter and outputs a second electronic signal with a response having a second time constant greater than the first time constant. The high pass filter has a filter time constant roughly equal to the second time constant and filters the first electronic signal, outputting a filtered first electronic signal in which changes in a level or value of the first electronic signal with transition times that are less than the filter time constant are passed. The summation unit receives the filtered first electronic signal and the second electronic signal and outputs a sum of the filtered first electronic signal and the second electronic signal.

A thermo sensor assembled to a unit under test has a metal plate, a passive component, and a package. The metal plate has an installation socket and at least one cable tray. The installation socket has a flat conducting base. The passive component has a main body mounted in the installation socket and at least one cable respectively mounted in the at least one cable tray and electrically connected to both the main body and the metal plate. The package integrally encapsulates the metal plate and the passive component. The conducting base is revealed outside the package and directly contacts the unit under test. Therefore, the passive component has a rapid and precise response to heat, and the thermo sensor can be applied to various positions and can get accurate readings without being interfered by the external environment.

Apparatus and associated methods relate to measuring temperature of a fluid within a hydraulic vessel using a temperature probe that has an annular recess circumscribing a projecting sensor tip. The annular recess is configured to permit fluid flow into an aperture region of a vessel wall through which the temperature probe contacts the fluid within the hydraulic vessel. Because the temperature probe projects from the annular recess within the aperture, a net projection dimension, as measured in a projection direction from an interior surface of the vessel wall proximate the aperture to a sensor, is less than a gross projection dimension, as measured in the projection direction from a bottom of the annular recess to the sensor tip. In some embodiments, this configuration advantageously improves a ratio of thermal conductivity between the fluid and the temperature probe and thermal conductivity between the temperature probe and a sensor housing.
