The SZMB-3 Magnetic-Electric Tachometer Sensor is an industrial-grade rotational speed detection device based on magnetic induction principle, designed for non-contact speed monitoring in various rotating equipment applications. By detecting periodic changes in gear teeth or magnetic markers on rotating surfaces, the device generates proportional pulse signals to provide reliable speed feedback for industrial automation systems.
Featuring an optimized magnetic-electric conversion structure, the sensor integrates high-performance magneto-sensitive components and signal processing circuits. This design enables effective capture of subtle magnetic field variations and conversion into stable electrical signals. With a detection range of 5-15mm, it supports both gear tooth and protrusion triggering modes, compatible with ferromagnetic materials and certain non-ferromagnetic targets. The aluminum alloy housing with sealing technology ensures excellent mechanical durability and environmental adaptability, maintaining stable operation within -30℃ to +80℃ temperature range.
Key technical advantages include strong electromagnetic interference resistance and broad response frequency range (1Hz-10kHz), accommodating diverse rotational speed measurement requirements. The standard square wave pulse output can be directly connected to PLC systems, tachometers, or data acquisition devices. Flexible mounting options allow both horizontal and vertical installation, enabling rapid deployment without complex calibration procedures.
Typical applications encompass motor speed monitoring, fan blade velocity detection, conveyor belt speed feedback, and pump operational status analysis. Particularly suitable for industrial environments with dust, oil contamination, or moderate vibration in metallurgical, power generation, and mining industries, this sensor delivers long-term stable speed monitoring performance. Its maintenance-free design and robust construction significantly reduce operational costs while ensuring measurement accuracy under challenging working conditions.
