Current Sensors, Transducers & Current Transformers

Current Sensors, Transducers & Current Transformers

General Linear Systems manufactures current sensors, current sensor transducers, and current transformers for OEMs, system builders, and technical buyers who need electromagnetic components built around real application requirements.

These components measure, monitor, or transform electrical current so larger systems can operate safely and accurately. They are commonly used in industrial equipment, infrastructure, commercial systems, aerospace, defense, security, chip manufacturing, and other applications where dependable current measurement is essential.

At GLS, we work from your print, electrical specifications, sample, or application requirements to help move projects from concept to production. Our California manufacturing team produces U.S.-made coils, transformers, magnetics, solenoids, and related electromagnetic components for a wide range of OEM applications.

Current Sensor Transducers

A current sensor transducer measures electrical current and converts it into a usable output signal for monitoring, control, or system protection. These devices help equipment monitor current levels, detect overload conditions, and provide feedback to controllers or monitoring systems.

Selecting the right transducer depends on factors such as current range, output signal, operating environment, mounting method, available space, and electrical requirements. Providing these details early in the design process helps GLS recommend the right manufacturing approach and streamline development.

Current Transformers & Instrument Transformers

A current transformer is a type of instrument transformer that reduces electrical current to a safe, measurable level for meters, relays, and monitoring equipment. Rather than routing high current directly through sensitive electronics, the transformer produces a proportional secondary current for accurate measurement.

GLS manufactures current transformers for OEM equipment, including low-voltage and portable current transformer designs. Every application has different electrical, mechanical, and mounting requirements, so we build products around the needs of the finished assembly.

Beyond current rating, engineers should also consider current ratio, burden, frequency, thermal conditions, and physical fit. Addressing these requirements early helps prevent sourcing issues later in production.

Engineering & Manufacturing Capabilities

General Linear Systems supports projects that require more than an off-the-shelf solution. We review customer prints, samples, and electrical specifications to develop current sensors, transformers, coils, and other magnetics that integrate with the final product.

Our manufacturing capabilities also include custom coils, solenoid coils, push-pull actuation components, actuator assemblies, solenoid valve components, and other electromagnetic products. This allows customers to source multiple related components from a single manufacturing partner while maintaining consistent design requirements throughout the project.

Applications & Why Choose General Linear

Current sensor transducers and current transformers are used wherever equipment needs reliable current measurement, circuit protection, or electrical feedback. Applications include industrial controls, power distribution equipment, commercial machinery, infrastructure systems, security equipment, aerospace and defense assemblies, and chip manufacturing equipment.

Whether you're developing a new design or replacing an existing component, GLS provides direct engineering support throughout the process. We work closely with customers to review specifications, reduce manufacturing challenges, and deliver components built for their application.

If your project requires a current sensor transducer, instrument transformer, low voltage current transformer, portable current transformer, or another electromagnetic component, contact General Linear Systems with your project details, specifications, print, or sample. Our engineering team is ready to review your application and provide a custom quote.

Why Choose General Linear Systems?

General Linear Systems combines coil design experience, in-house bobbin making capability, machine shop resources, and custom coil winding under one U.S.-based manufacturing partner. GLS supports custom sensor and transformer needs from prototype and sample runs to recurring production quantities.

Our computerized design support helps evaluate electromagnetic requirements early in the process, reducing guesswork around size, winding, electrical performance, and manufacturability. For engineers, that means a more informed design path. For sourcing teams, it means a clearer route from RFQ to production.

When you need custom current sensors, current transformers, transducers, or related magnetics built around your application, GLS can help review your print, specifications, or project requirements.

FAQs

What is a current sensor transducer?

A current sensor transducer is a device that measures electrical current and converts it into a signal a system can use. That signal may help monitor equipment, support controls, identify overloads, or provide feedback to another circuit. Engineers should consider current range, output signal, voltage, space limits, mounting needs, and operating environment before requesting a quote.

What is an instrument transformer?

An instrument transformer is a transformer used to make electrical current or voltage easier and safer to measure. A current transformer is one common type of instrument transformer. It reduces current to a proportional level that meters, relays, or monitoring equipment can read. These components are often used in power monitoring, control panels, and equipment protection systems.

When should a low voltage current transformer be used?

A low-voltage current transformer should be used when a system needs to measure or monitor current in a low-voltage electrical application. It can help provide a usable current signal without routing higher current directly through sensitive monitoring equipment. The correct design depends on current rating, ratio, frequency, burden, mounting style, space limits, and how the transformer connects to the larger system.

Do you manufacture custom current transformers?

Yes, General Linear Systems manufactures current transformers based on customer specifications, prints, samples, or application requirements. GLS can support designs in which electrical performance, physical size, lead configuration, mounting, and production volume must match the final assembly. Sharing your current range, voltage, frequency, dimensions, and use case will help our team review the best path forward.

Can you help with prototype development?

Yes, GLS can help with prototype and sample development for current sensors, transducers, current transformers, and related electromagnetic components. Our team can review early specifications, existing samples, drawings, or application goals to help determine what should be built. Providing as much detail as possible at the RFQ stage can help reduce revisions and support a smoother move into production.
