摘要： A heater system includes an integrated heater device and a control system. The integrated heater device includes a thermocouple for measuring temperature and one or more multiportion resistive elements that are operable as heaters to create a temperature differential between the fluid and air to detect the fluid, and as sensors to measure a fluid level. The control device operates the integrated heater device as a sensor or heater based on one or more performance characteristics of the heater system and self-calibrates the heater device.

摘要： A fluid level sensing device includes a substrate (210) and a sensing die (216) cantilevered at one end from the substrate. A number of sensing components (218), preferably thermal or impedance sensing components, are disposed on the sensing die and detect a fluid level in a fluid reservoir. A protective member (208) is also cantilevered at one end from the substrate alongside the sensing die. Electrical interconnects (212) output data collected from the number of sensing components. A number of sensing dies may be provided to lengthen the sensing device, in which case the protective cover extends alongside and parallel to the number of sensing dies.

摘要： An electronic liquid level gauge assembly includes an electronic display located in a housing connected to a tank. The display has first and second display portions for indicating liquid level condition. A first electronic sensor senses a change in magnetic field of a magnet associated with a liquid level transducer, with magnet rotation being proportional liquid level change. A processor determines a temperature-compensated liquid level condition by correlating the liquid level signal with temperature measurement of the liquid. A temperature-compensated vapor space can also be calculated based on tank information and properties of the liquid. Signals related to the temperature-compensated liquid level and vapor space are sent to the display and wirelessly transmitted to a smart phone or the like for remotely viewing the tank information. The smart phone also includes a special app for sending information, firmware updates, and display configuration data to the electronic gauge assembly.

摘要： A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

摘要： Systems and methods for monitoring temperature distribution in downhole equipment using magnetostrictive probes. In one embodiment, an ESP motor has a stator with a rotor and shaft rotatably positioned within the stator. Magnetostrictive sensors are positioned within the motor. Each magnetostrictive sensor has a transducer, a probe, and electronic circuitry coupled to the transducer. The circuitry generates an initial electrical signal that is conveyed to the transducer. The signal passes through one or more coils in the transducer, generating magnetic fields that induce an acoustic signal in the probe. The acoustic signal propagates through the probe and waves are reflected from reflection points in the probe. The transducer senses the reflected acoustic waves and provides corresponding electrical signals to the circuitry, which determines timing intervals associated with the reflected waves and uses this information to determine temperatures at one or more locations in the probe (hence in the monitored equipment).

摘要： Apparatuses are provided to facilitate sensing fluid within a fluid system, such as a coolant-based cooling apparatus for removing heat generated by one or more electronic components. The apparatus includes a plug configured to couple to a wall of the fluid system at an opening in the wall and to form a fluid-tight seal about the opening. The plug includes a fluid a fluid-sensor-receiving space configured to receive a fluid sensor, and when the plug is coupled to the wall at the opening, to position the fluid sensor at the opening in a manner to facilitate sensing of fluid within the system. The fluid sensor is removable from the plug without requiring uncoupling of the plug from the wall. In one implementation, the fluid sensor is a proximity sensor, and the plug is fabricated of a non-conductive material, and the wall a conductive material.

摘要： A sensor for determining liquid level in a liquid reservoir can include a primary inductor and a secondary inductor to be associated with sides of the reservoir that changes shape as a volume of liquid changes or is displaced within the liquid reservoir. The sensor can include an electrical power source to inductively couple the primary inductor and the secondary inductor. The liquid level sensor can include an inductive coupling measurement device associated with the primary inductor and/or the secondary inductor to measure a characteristic indicative of the inductive coupling of the primary inductor and the secondary inductor (e.g., a distance between inductors). As liquid volume changes and the reservoir deforms, the inductors move relative to each other and a voltage change occurs to determine a liquid level in the reservoir. A sensor kit is provided.
