How to choose Hall effect sensors

Weikewei Technology has a range of different options for our DC current transformers. Some things to consider when choosing our sensors:

1. Choose open-loop or closed-loop Hall sensor

Weikewei Technology provides DC current sensors with open-loop and closed-loop sensors. Open loop sensors have lower costs and provide low insertion loss, decent response time, and compact size. Closed loop sensors are relatively immune to electrical noise and provide high linearity and low temperature drift.

2. Choose open or fixed type

We sell both open and fixed sensors simultaneously. Open end sensors are very convenient because they can be placed around existing conductors without disconnecting them. Fixed sensors are difficult to install, but they are also more likely to include closed-loop sensors and provide better linearity. We sell both open-ended and fixed sensors simultaneously. Open end sensors are very convenient because they can be placed around existing conductors without disconnecting them. Fixed type is more difficult to install, but it is also more likely to include closed-loop sensors and provide better linearity.

3. Output selection

Current sensors can output voltage or amperage within different value ranges. We sell Hall sensors with various outputs, including 4-20mA, 5V, and more.
