  • Patent number: 12025639
    Abstract: The invention involves a multimeter with a meter probe module and phasing probe module capable of wireless communication, proximity measurements, and accurately reading phase degrees. The meter probe module and the phasing probe module can communicate wirelessly, via a wired cable interface, or any combination thereof. The meter probe module and phasing probe module have unique radio frequency serial numbers that allow the probe modules to only communicate with its paired partner probe module while ignoring all other probe modules. The multimeter has a measurement point capable of taking direct contact measurements. The multimeter also has a measurement point capable of taking a voltage measurement without directly contacting the object to be measured. This is accomplished by taking voltage readings from the electric field of the air surrounding said object. The improved multimeter may allow an operator to more safely gather accurate information about an object being measured.

The measurement system includes a signal interface cable having a connector where a probe can be releasably connected to the system. The cable and attached connector are a removable and replaceable part of the system, separate from the probe. The measurement system provides an output signal imitating a standard input signal configuration used by other equipment.

  • Patent number: 10180450
    Abstract: A transmitter with universal terminals supports flexible connection of an RTD sensor. The transmitter includes a plurality of terminals, a first switch, a second switch, and a microcontroller. The first switch is coupled to the plurality of terminals and a current source. The second switch is coupled to the plurality of terminals and a sink resistor. The microcontroller receives an indication that a sensor is connected to an undetermined number of the terminals. The microcontroller transmits control signals to the first switch and the second switch to test a voltage differential between each of a plurality of combinations of the terminals. The microcontroller determines which of the terminals are coupled to the sensor. The microcontroller sets the determined terminals as inputs received from the sensor.

  • Patent number: 9752936
    Abstract: In a temperature sensor, two seal members seal the open opposite ends of a cladding member (a forward end and a rear end), so that water absorption by an insulator of a sheath member can be restrained. The seal members are formed to have an insulation resistance equal to that of a conductor-fixing material. Therefore, even when the temperature sensor is used in a high-temperature environment, the insulation performance of the seal members does not become lower than the insulation performance of the conductor-fixing material, so that the formation of a leakage current path can be suppressed. According to the temperature sensor, the electrical property of a temperature sensitive element can be sensed accurately, and a reduction in the accuracy of temperature sensing can be restrained.

  • Patent number: 9065280
    Abstract: An energy storage system having one or more battery packs and a system controller for controlling the battery packs. Each battery pack has rechargeable storage cells and a battery pack controller in communication with the system controller. Through the operation of the system controller, battery packs with different initial charge states can be operated in parallel during a charge process and a discharge process. Discharging multiple battery packs in parallel offers not only a higher capacity and a longer run time than is available from a single battery pack, but also offers higher peak currents than available from a single battery pack, which are important in motor control applications. A battery pack design including a battery pack connector with both power and control contacts supporting user replacement of the battery packs.

  • Publication number: 20150137050
    Abstract: A metal-oxide sintered body for a temperature sensor that can be installed in a combustion engine and components connected to the engine in order to sense temperature uses metal oxide. The metal-oxide sintered body has particles with large resistance values and particles with small resistance values mixed therein. The particles with the small resistance values may serve as a main resistance component in the temperature range of 0° C. to 500° C., and the particles with the large resistance values may contribute to the total resistance in proportion to the mixing ratio in the temperature range of 500° C. to 900° C. Thus, the metal-oxide sintered body enables a single sensor to measure all resistances, and can be used in an exhaust device or the like of a motor vehicle that requires temperature measurement over a wide range of temperatures.
