Overview

High temperature Hall speed sensor is used to detect the speed and linear velocity of the wheel axle, and the speed of the measured object can also be obtained through calculation and processing. This sensor has good low-frequency and high-frequency characteristics. Low frequency can reach 0Hz, used for zero speed measurement of rotating machinery, up to 20KHz, which can meet the high-speed measurement requirements of the vast majority of industrial fields. The sensor can provide two types of speed signals with a certain phase difference, thus enabling forward and reverse discrimination. Easy installation, no contact with the measuring gear, no wear, output waveform is square wave, with a duty cycle of about 50%; Wide speed measurement range, wide temperature adaptability, strong vibration resistance, with power polarity protection and output short circuit

High temperature Hall sensor for rotational speed

1.Introduction:

High temperature Hall sensor for rotational speedUsed to detect the rotational speed and linear velocity of the wheel axle, the speed of the tested object can also be obtained through calculation and processing. This sensor has good low-frequency and high-frequency characteristics. Low frequency can reach 0Hz, used for zero speed measurement of rotating machinery, up to 20KHz, which can meet the high-speed measurement requirements of the vast majority of industrial fields. sensorTwo speed signals with a certain phase difference can be provided, so forward and reverse discrimination can be performed.Easy installation, no contact with the measuring gear, no wear, output waveform is square wave, with a duty cycle of about 50%; Wide speed measurement range, wide temperature adaptability, strong vibration resistance, power polarity protection and output short circuit protection, in compliance with DIN867 standard.
