SZG-411A非接觸手持式數(shù)字轉(zhuǎn)速表/SZG411A
產(chǎn)品概述（中英文）
SZG-411A非接觸手持式數(shù)字轉(zhuǎn)速表是一款采用光電反射原理設(shè)計(jì)的高精度便攜式測(cè)量工具，適用于電機(jī)及各類機(jī)械設(shè)備的轉(zhuǎn)速檢測(cè)。其袖珍型設(shè)計(jì)便于攜帶，通過(guò)非接觸方式（紅色LED可見(jiàn)光源）實(shí)現(xiàn)測(cè)量，有效避免機(jī)械接觸帶來(lái)的干擾。該產(chǎn)品具備上限報(bào)警、最大值/最小值顯示等實(shí)用功能，可滿足工業(yè)場(chǎng)景中的多樣化需求。測(cè)量范圍覆蓋10～50000r/min，采樣時(shí)間僅需1秒，數(shù)據(jù)通過(guò)5秒液晶屏清晰顯示，精度根據(jù)轉(zhuǎn)速區(qū)間分為±1r/min（10～11999r/min）和±2r/min（12000～29999r/min）。工作溫度適應(yīng)0～40℃環(huán)境，內(nèi)置三節(jié)五號(hào)電池供電，續(xù)航穩(wěn)定。
The SZG-411A non-contact handheld digital tachometer is a high-precision portable device based on photoelectric reflection principles, designed for measuring rotational speed of motors and mechanical equipment. Its compact size ensures easy operation, while the non-contact method (using red LED light source) eliminates mechanical interference. Features like upper-limit alarm and max/min value display enhance practicality for industrial applications. With a measuring range of 10～50000r/min and 1-second sampling time, results are displayed on a 5-second LCD screen. Accuracy varies by range: ±1r/min (10～11999r/min) and ±2r/min (12000～29999r/min). It operates reliably in 0～40℃ environments powered by three AA batteries. 1216
核心功能與設(shè)計(jì)（中英文）
該轉(zhuǎn)速表采用微型計(jì)算機(jī)集成電路芯片，確保快速采樣與數(shù)據(jù)穩(wěn)定性。其反射式測(cè)量距離為50～150mm，過(guò)量程時(shí)自動(dòng)顯示“OVER”提示。外殼采用ABS塑料材質(zhì)，兼顧輕量化與耐用性。用戶可通過(guò)反射標(biāo)記輕松對(duì)準(zhǔn)旋轉(zhuǎn)物體，實(shí)現(xiàn)一鍵測(cè)量。附加功能包括線速度計(jì)算（1～5000m/min）和頻率測(cè)量，適用于多種工業(yè)場(chǎng)景。
Equipped with a dedicated microcomputer IC chip, the tachometer guarantees rapid sampling and data stability. The reflective measurement distance is 50～150mm, with an "OVER" indicator for out-of-range values. The ABS plastic casing balances lightweight design and durability. Users can align the device with rotating objects via reflective markers for one-touch operation. Additional functions include linear speed calculation (1～5000m/min) and frequency measurement, catering to diverse industrial needs. 6815
應(yīng)用場(chǎng)景與優(yōu)勢(shì)（中英文）
SZG-411A廣泛應(yīng)用于電力、石化、冶金等領(lǐng)域，尤其適合不便直接接觸的旋轉(zhuǎn)設(shè)備監(jiān)測(cè)。其高分辨率LCD背光屏在弱光環(huán)境下仍可清晰讀數(shù)，且具備數(shù)據(jù)存儲(chǔ)功能（最后一次測(cè)量值及過(guò)程極值）。相比傳統(tǒng)接觸式儀表，該產(chǎn)品減少磨損風(fēng)險(xiǎn)，提升測(cè)量效率。
Ideal for industries like power, petrochemicals, and metallurgy, the SZG-411A excels in monitoring rotating equipment where direct contact is impractical. The high-resolution LCD with backlight ensures readability in low-light conditions, while data storage (last value and extremums) enhances traceability. Compared to contact-based models, it minimizes wear risks and improves operational efficiency. 101722
