Hall Open-Loop

What is Hall effect sensor?

Among magnetic sensors, those sensors which use the Hall effect are called Hall effect sensors. Hall effect sensors consist of several parts. First, it contains a Hall element that outputs a Hall voltage (HV) generated through the Hall effect. Second, it contains a Hall IC which makes the Hall output a high/low digital output through the IC process. Third, it contains a linear Hall IC that amplifies and linearizes the Hall output.

 

As one of the leading Hall effect sensor manufacturer, Luksens is capable of providing different kinds of Hall effect sensor products from mould designing, production to testing.

 

What’s the advantages of Hall effect sensor?

Hall effect sensor is a sensor that can realize magnetoelectric conversion, which can detect magnetic fields and their changes. Hall effect sensors have many advantages, they are firm in structure, small in size, long in life, easy to install, low in power consumption, high in frequency, resistant to vibration, and not afraid of pollution or corrosion by dust, oil, and salt spray. The Hall switch device has the advantages of no contact, clear output waveform, no jitter, high position repeatability, etc.

 

With over 20 years experience in sensor solution provider, Luksens, a Hall effect sensor supplier, are always committed to exceeding customer expectations through innovation and the continued improvement of our products and services.

 

Due to the ability to feel the magnetic field in a static state, simple structure, small size, light weight, wide frequency band (from DC to microwave), good dynamic characteristics, large dynamic range, long life and non-contact measurement and more, hall effect sensors are increasingly widely used in detection technology, automatic control technology and information processing. The future development trend of Hall effect sensor will be high sensitivity, high precision and high stability, and it will develop more rapidly on the basis of the development of microelectronics technology.

 

Luksens, with a good reputation as Hall effect sensor supplier, has been committed to being a reliable partner for users in the areas of high-quality sensor solutions. Through our professional team of research & development, manufacture, sales, and service, we offer innovative hall effect sensor solutions in Energy Management, Motion & Drives, Domestic Appliance, Welding, EV Chargers, Pumps, Air Compressors, Air Conditioners, Heat Pumps, Mechanical and Plant Engineering etc.

 

Two main categories of Hall effect sensor

Linear Hall effect sensor can be divided into two types, which are open-loop and close-loop. As a trusted Hall effect sensor supplier, Luksens provides both open open-loop Hall effect sensor and close-loop Hall effect sensor on current measurement from 5A to 2000A, with accurate low temperature drift linear hall sensor and digital programmable amplification technology.

 

Open-loop Hall effect sensor

Typically, open-loop Hall effect sensors use a magnetic sensor to output voltage proportional to carried current, then amplified to an analog output proportional to the current in the conductor. In terms of its structure, the conductor passes through the center of the ferromagnet to concentrate the magnetic field, while the magnetic sensor is placed in the gap of the ferromagnet.

 

Luksens, a reliable Hall effect sensor manufacturer since 2001, provides open-loop Hall effect sensors with C02, C03, C05, C06, K03, K18，AC3 series.

How to choose open-loop Hall effect sensor and close-loop Hall effect sensor?

 

The choice of open-loop Hall effect sensor versus close-loop Hall sensor requires consideration of accuracy and response time. If the application requires high precision, a close-loop Hall effect sensor is usually selected, which can eliminate the system sensitivity nonlinearity error mentioned above. In some applications, fast response is required to protect semiconductor devices such as IGBTs and MOSFETs so that the current in the application can be better controlled. If it can have sufficient accuracy and response speed, due to its inherent advantages in size, power consumption, etc., an open-loop Hall effect sensor is also an ideal choice. Luksens, an experienced Hall effect sensor manufacturer and Hall effect sensor supplier, has developed this new open-loop solution, which is smaller, has high precision and fast response, and is more economical than close-loop solutions.
