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.

Disclosed is a sensor, comprising: a housing; a detecting element provided inside the housing; a first cylinder provided inside the housing and sleeved outside the detecting element, the first cylinder having an amount of elastic deformation in a direction intersecting a surface around the detecting element; a particle filler, for filling an inner cavity of the housing. When external environment produces mechanical shock to the sensor or the sensor produces mechanical vibration, the limiting action of the first cylinder and the particle filler enables the detecting element to only have very little vibration displacement or even no vibration displacement with respect to the housing. The external mechanical shock can be partially or completely absorbed by the first cylinder and the particle filler, so as to reduce vibration displacement of the detecting element caused by the shock.

An indicator tab comprising a thermochromic material is mounted in thermal contact with an electrical component in an enclosure. An observation port in a cover of the enclosure is juxtaposed with the indicator tab enabling visual observation of the thermochromic material indicating a temperature of the component. Each indicator tab comprises a visible portion on one end of an arm where the thermochromic material is located and a fastening portion on the other end thermally contacting the component. The indicator tab is composed of a material having a high thermal conductivity to efficiently conduct heat toward the visible portion. In an enclosure where the components are close together, the arm may be composed of a high electrical resistivity material to avoid creating a short circuit with other components. Alternately, in an enclosure where the components are not closely positioned, the arm may be composed of a metallic material.
