CZ-20B固定磁性转速表/CZ20B
产品概述
CZ-20B固定磁性转速表是一款机械式指针测量仪表，专为各类旋转设备设计，适用于卷盘式喷灌机、发动机及其他工业设备的转速监测。该产品采用磁性感应原理，通过指针直观显示转速值，具备结构简单、安装便捷、运行稳定等特点，可满足不同场景下的转速测量需求。其核心部件采用密封防尘设计，能在-20℃至50℃环境温度及≤85%湿度条件下稳定工作，确保数据的准确性和设备可靠性。235
技术特点
该转速表通过磁钢与罩帽的相对转动产生电涡流，带动指针顺时针单向显示转速，转轴与指针同向转动，测量误差控制在测量上限值的±1.5%以内。温度每变化10℃时，附加误差不超过基本误差限值，且允许指针在合理摆幅内轻微抖动。支持多种量程规格，如0-800r/min对应0-117m/h的线性比例，特殊比例可根据需求定制。其陶瓷与耐弧塑料组合的灭弧结构能有效减少触头损耗，延长使用寿命。4812
应用场景
CZ-20B广泛应用于柴油机、船舶辅助系统、农业机械及轨道交通等领域，特别适合需要长期连续监测的中低速场景。例如在喷灌设备中实时监控卷盘转速，或用于机车电机转速的异地安装监测。其抗震性能和防尘设计使其在恶劣工业环境中表现优异，同时兼顾了经济性与功能性，是传统离心式转速表的理想替代方案。3914
Product Introduction
The CZ-20B Fixed Magnetic Tachometer is a mechanical dial instrument designed for rotational speed measurement of various machinery, including reel irrigators, engines, and industrial equipment. Utilizing magnetic induction principles, it features a unidirectional clockwise pointer display with sealed construction for dust resistance. Operating reliably in temperatures from -20℃ to 50℃ and up to 85% humidity, it provides stable performance under demanding conditions. The simplified structure allows easy installation without complex calibration procedures.1610
Key Features
This tachometer employs eddy current generation through magnetic rotor interaction, achieving ±1.5% full-scale accuracy at 20±2℃. Its temperature coefficient maintains error within specified limits when ambient changes by 10℃. The combination of ceramic arc chamber and anti-arc plastic cover minimizes contact wear while supporting customizable scaling (e.g. 0-800r/min corresponds to 0-117m/h line speed). The hermetically sealed movement prevents particulate ingress, ensuring longevity in dusty environments. Pointer oscillation is constrained within tolerance range during operation.71115
Typical Applications
Ideal for medium-low speed monitoring, the CZ-20B serves reliably in agricultural irrigation systems, marine auxiliary engines, and rail traction equipment. Its vibration resistance suits mobile applications like diesel generator sets, while the compact design facilitates space-constrained installations. The device offers cost-effective rotational speed visualization where electrical power supply is unavailable or impractical, bridging mechanical and digital measurement solutions.1316
