Import - Hall Sensor - Manufacturer's Supply [Weikewei]

According to the function of Hall devices, Hall sensors can be divided into two types: linear Hall sensors and switch type Hall sensors:

1)linear Hall sensor

A linear Hall sensor is composed of Hall elements, linear amplifiers, and emitter followers, and outputs analog signals.

2)Switch type Hall sensor

A switch type Hall sensor is composed of a voltage regulator, Hall element, differential amplifier, Schmitt trigger, and output stage, which outputs digital signals.hall sensor It is a current and voltage sensor made based on the Hall effect principle. According to different ways of processing Hall potential, Hall.

Sensors can be divided into the following two categories:

1) The first type is to directly amplify the Hall potential and provide it to the detection instrument or control equipment, which is called direct detection Hall potentialcurrent sensor . This type of sensor has a high voltage resistance level, low cost, and stable performance, but its accuracy is greatly affected by temperature changes, and its dynamic response characteristics are not ideal. Our company adopts circuit compensation to successfully solve the above problems.

2) The second type is magnetic field balanced Hall sensors, which use single or dual sensorshall sensor It operates in a zero magnetic flux state and has the following characteristics:

(1) Wide measurement range, capable of measuring various currents such as DC, AC, pulse current, etc.

(2) Good electrical isolation performance.

(3) High measurement accuracy and good linearity.

(4) Strong ability to resist interference from external electromagnetic and temperature factors.

(5) High current rise rate and fast response speed.

(6) Strong overload capacity.

(7) Small size, light weight, easy and convenient installation.

At present, magnetic field balanced Hall sensors are the main products.
