Top Current Sensor Services Companies

An open-loop sensor reads the magnetic field around a conductor directly, which keeps it small and inexpensive but less accurate over temperature. A closed-loop sensor drives a compensating winding to cancel the field, giving better accuracy, linearity and response at a higher cost and larger size.

It depends mostly on how far the design departs from a standard part. A modified catalog sensor moves quickly from samples to supply, while a new core, winding or housing adds tooling, prototype rounds and qualification testing, and automotive or medical approval adds more steps.

Ask which sensors it builds itself, how it calibrates them, what accuracy holds across your temperature range, what isolation testing each unit receives, and which quality certifications it holds. Also ask for test reports from a similar application and how it handles lot traceability.

Current sensor services focus on the measuring component itself: its design, materials, calibration and supply. Sensor integration works one level up, connecting many sensor types to controllers, data systems and software so the readings drive decisions in a machine or plant.
