SZGB-4B Photoelectric Tachometer Sensor Product Introduction
The SZGB-4B Photoelectric Tachometer Sensor is a high-performance rotational speed measurement device based on photoelectric conversion principles, specifically developed for real-time monitoring of industrial equipment and rotating machinery. Utilizing non-contact detection technology, it converts mechanical movement into identifiable electrical pulse signals by capturing reflective markers or specific structural features on rotating components, delivering precise operational data for equipment status analysis.
Featuring a compact integrated design, the sensor housing combines high-strength engineering plastics with metal alloys, achieving optimal balance between lightweight construction and mechanical durability. The optical system integrates high-sensitivity photoelectric receivers with adaptive gain circuitry, ensuring stable detection across a broad measurement range of 0.1-10,000 RPM. Equipped with multi-stage filtering modules, the device effectively suppresses electromagnetic interference and ambient light noise, maintaining measurement consistency within an operational temperature range of -30℃ to +85℃.
Standard signal output interfaces provide linearly proportional square wave pulse signals corresponding to rotational speed, ensuring compatibility with mainstream PLCs, data acquisition cards, and industrial control systems. Installation flexibility is enhanced through threaded mounting and bracket assembly options, supporting both axial and radial detection configurations. This adaptability makes the sensor suitable for diverse mechanical structures including motor shafts, gear assemblies, and conveyor rollers. Typical applications span wind turbine monitoring, pump unit protection, printing press synchronization, and laboratory instrument calibration, serving as a dependable data source for predictive maintenance and process control.
Usage guidelines: Maintain an effective detection distance of 5-50mm between the sensor head and reflective markers during installation. Regular cleaning of optical windows is recommended to prevent signal degradation caused by oil contamination. For optimal performance, use shielded cables and route wiring away from high-power electrical equipment to minimize signal interference.
