CR Magnetics is a US-based company that specializes in the design and manufacture of a wide range of current, voltage, and power sensors, transformers, and transducers that are used in industrial, commercial, and utility applications.
Founded in 1974 in St. Louis, Missouri.
Initially focused on producing current transformer components for other manufacturers.
In 1978, the company began producing its own line of standard products.
In 1996, CR Magnetics moved to a new facility in Fenton, Missouri.
Acquired by Halma plc, a global group of life-saving technology companies, in 2016.
A company that produces a range of current and voltage sensors, as well as power monitoring products.
A manufacturer of current, voltage, and power transducers, as well as environmental sensors and control products.
A brand of sensors and current transformers offered by AutomationDirect, an industrial automation supplier.
CR Magnetics produces a range of AC and DC current sensors that can measure from a few amps to several thousand amps, including split-core, solid-core, and Rogowski coil sensors.
The company offers a variety of current transformers, including donut, split-core, solid-core, and current switch transformers, that are used to accurately measure current in electrical systems.
CR Magnetics' power transducers accurately measure AC or DC power usage, and can monitor true power, reactive power, apparent power, and power factor.
A current transformer is an electrical device that is used to measure electrical current. It works by inducing a current in a secondary coil that is proportional to the current in a primary coil.
A Rogowski coil is a type of current sensor that consists of a coiled wire that measures the magnetic field created by a current-carrying conductor. It is commonly used in high-current applications where other types of current sensors may not be able to handle the current.
Power factor is the ratio of real power to apparent power in an electrical system. It represents the percentage of electrical energy that is being used effectively to perform work, and is often used as an indicator of the efficiency of electrical equipment.
The output signals of CR Magnetics' products vary depending on the type of product and the specific model, but may include voltage outputs, current outputs, or frequency outputs.
CR Magnetics' products are used in a wide variety of industries, including industrial automation, HVAC, power generation, and renewable energy. They are also used in building automation, data centers, and transportation applications.
