SZCB-01-L148 Integrated Speed Sensor

SZCB-01-L148The integrated speed sensor is a magnetic resistance speed sensor developed by Xuzhou Liuhe Measurement and Control Technology Co., Ltd., mainly used to measure the speed of the unit. It generates signals by sensing the motion of nearby ferromagnetic objects, thereby achieving the measurement of rotational speed‌1When the ferromagnetic object of the unit is in motion, it will enter the magnetic field range of the sensor, and the proximity of the ferromagnetic object will change the strength of the magnetic field, thereby causing a change in the magnetic resistance inside the sensor‌.

Main Features

‌working principle‌：Adopting the principle of electromagnetic induction, it has the characteristics of large output signal, good anti-interference performance, and no need for external power supply. It can be used in harsh environments such as smoke, oil and gas, and water and gas‌.

‌Gear requirements‌Gear materials should be made of metal materials with strong magnetic permeability, and involute tooth profiles are the most suitable. Using large modulus tooth profiles or other tooth profiles will result in significant waveform distortion‌.

‌physical indicators‌：Approximate weight120g, anti vibration20gThe working temperature range is-10to+120℃‌.

Installation precautions

‌Gear installation‌：Install a gear made of magnetic conductive material (such as iron, steel, etc.) on the tested shaft, which needs to be machined into involute teeth and the modulus should be greater than4.

‌Sensor installation‌：Install the sensor on a specialized speed measuring bracket, ensuring that the sensor is radially aligned with the gear and the installation clearance is maintained at0.5~2mmbetween‌.

‌cable connection‌：The signal output cable of the sensor is a four core shielded wire, and the lead color and function are as follows: red is24VPower cord, black is the common ground wire（com）Yellow is the signal output1Line, green for signal output2line‌.

speed sensorSZCB-01-A00-B080-C00-D05It is a high-performance non-contact magnetic electric speed measurement device designed specifically for speed monitoring of industrial rotating machinery. This sensor adopts * magnetic induction technology, which can accurately measure the rotational speed of various magnetic materials and is widely used in equipment condition monitoring systems in industries such as power, petrochemicals, metallurgy, and mechanical manufacturing.

This sensor adoptsM16×1Standard threaded housing design, easy to install and has good mechanical strength. Special attention should be paid to protecting the threaded structure from damage during installation, ensuring that the hex nut can rotate freely and lock reliably. The correct installation method requires the sensor to maintain appropriate clearance with the measured gear (usually recommended)0.5-1.5mm）This gapδThe size directly affects the amplitude of the output signal, so it is necessary to minimize the gap as much as possible while ensuring a safe distance to improve measurement sensitivity.

SZCB-01-A00-B080-C00-D05The working principle of the speed sensor is based on the electromagnetic induction effect. When the teeth or grooves of the gear pass through the end of the sensor, it will change the magnetic field distribution around the sensor, thereby generating an alternating voltage signal in the induction coil. The frequency of this signal is proportional to the rotational speed and can be converted into a standard rotational speed value after subsequent circuit processing. Sensors do not require external power supply and rely on the induced potential generated by the movement of the object being measured, making them inherently safe.
