What is the working principle of ZS-04 speed sensor?

abstract
ZS-04 speed sensor is a speed measurement device based on electromagnetic induction principle, widely used in the industrial field for measuring and monitoring the speed of mechanical equipment. It has the characteristics of high anti-interference, strong output signal, and no need for external power supply, making it suitable for harsh environments.

The ZS-04 speed sensor adopts the principle of electromagnetic induction, which generates changes in magnetic flux through the rotation of the induction gear, thereby generating periodic induced electromotive force in the induction coil. After amplification and shaping, output an electric pulse square wave signal.

What are the main technical parameters of ZS-04 speed sensor?
-Measurement range: 100-10000 revolutions per minute.
-DC resistance: 230 Ω~270 Ω (low resistance type) or 470 Ω~530 Ω (high resistance type).
-Working temperature:- 20 ℃ to 120 ℃.
-Installation gap: 1mm.
-Vibration resistance: 20g.
-Output signal: Square wave signal, amplitude proportional to speed.

What are the installation requirements for ZS-04 speed sensor?
-During installation, ensure that the sensor housing threads are undamaged and the hex nut rotates freely.
-The tested gear should be made of a metal material with strong magnetic permeability, with an involute gear profile and a modulus of 2-4.
-The installation clearance between sensors and gears is generally 0.5-1mm.

What are the application scenarios of ZS-04 speed sensor?
The ZS-04 speed sensor is suitable for measuring the speed of various industrial scenarios, including steam turbines, generators, mechanical transmission equipment, etc. It can also be used for measuring car ABS, train wheel speed, aircraft engine speed, etc.
