In electrical engineering, current sensing is any one of several techniques used to measure electric current. The measurement of current ranges from picoamps to tens of thousands of amperes. The selection of a current sensing method depends on requirements such as magnitude, accuracy, bandwidth, robustness, cost, isolation or size. The current ...
Tagg had started as a Qualcomm subsidiary in 2010 and released its tracking device one year before Whistle. [1] [15] By 2015, Whistle had distributed 100,000 devices and had about 40 employees. [1] In April 2016, Whistle was acquired by Mars Petcare, the pet product subsidiary of the food and candy bar maker Mars, for $117 million. [16]
A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Utilizing a single-ended optical fiber wrapped around the current conductor, [1] FOCS exploits the magneto-optic effect (Faraday effect). [2] The FOCS can measure uni- or bi-directional DC currents up to 600 kA, with an accuracy within ±0.1% of the measured value.
Luna Innovations Incorporated is an American developer and manufacturer of fiber-optics- and terahertz-based technology products for the aerospace, automotive, communications, defense, energy, infrastructure, security, and silicon photonics industries.
Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8-volt differential. The non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.
Mechanical sensing methods using potentiometers, Hall effect sensors, and incremental encoders have historically seen use as the basis for motion tracking but they have since mostly been replaced for that purpose by MEMS and other types of integrated circuit technologies. These sensors are used to track mechanical connections between a control ...
Eddy current sensors are displacement sensors that use the principle of eddy current formation to sense displacement. These sensors measure shaft displacement in rotating machinery and have been around for many years as they offer manufacturers high-linearity, high-speed measurements, and high resolution. [ 1 ]
The company released its first GPS dog tracker prototype at CES 2013 in Las Vegas. Their first generation tracking devices, released in 2014, received the Innovation of the Year Award at the Austrian Future Zone Awards. 2018 saw Tractive reach a milestone of 100,000 users worldwide, as well as receive a 7-figure investment from Monkfish Equity.
