DT-6234B光電式轉(zhuǎn)速表是一款基于先進(jìn)光電傳感技術(shù)研發(fā)的非接觸式轉(zhuǎn)速測(cè)量?jī)x器，專為工業(yè)設(shè)備、機(jī)械制造、汽車維修及科研實(shí)驗(yàn)等領(lǐng)域設(shè)計(jì)。它通過光學(xué)原理實(shí)現(xiàn)無接觸測(cè)量，有效避免了傳統(tǒng)接觸式儀器可能造成的設(shè)備損傷，同時(shí)滿足了特殊場(chǎng)景下的安全檢測(cè)需求。

該轉(zhuǎn)速表具有高精度測(cè)量能力，測(cè)量范圍覆蓋2.5 RPM至99,999 RPM，分辨率為0.1 RPM（2.5至999.9 RPM）和1 RPM（1,000 RPM以上），測(cè)量準(zhǔn)確度為±（0.05% +1個(gè)字）。它配備了5位31mm字高的超大液晶顯示屏，帶有藍(lán)色背光，即使在光線較暗的環(huán)境中也能清晰讀數(shù)。

DT-6234B還具備智能數(shù)據(jù)處理功能，能夠自動(dòng)記憶最大值、最小值和最后測(cè)量值，并可存儲(chǔ)多達(dá)96組測(cè)量數(shù)據(jù)。其有效測(cè)量距離為50mm至500mm，適用于多種旋轉(zhuǎn)物體的測(cè)量。此外，該轉(zhuǎn)速表采用6MHz石英晶體振蕩器作為時(shí)基，量程可自動(dòng)切換，電源為4×1.5V UM-3電池或外接DC 6V直流穩(wěn)壓電源。

The DT-6234B Photoelectric Tachometer is a non-contact tachometer developed based on advanced photoelectric sensing technology, designed for industrial equipment, mechanical manufacturing, automotive repair, and scientific research experiments. It achieves non-contact measurement through optical principles, effectively avoiding potential equipment damage caused by traditional contact instruments, while also meeting safety inspection needs in special scenarios.

This tachometer is capable of high-precision measurement with a range of 2.5 RPM to 99,999 RPM, a resolution of 0.1 RPM (2.5 to 999.9 RPM) and 1 RPM (above 1,000 RPM), and an accuracy of ±(0.05% +1 digit). It features a large 5-digit LCD display with 31mm high characters and blue backlight, ensuring clear readings even in low-light conditions.

The DT-6234B also has intelligent data processing capabilities, automatically remembering the maximum, minimum, and last measurement values, and can store up to 96 sets of measurement data. Its effective measurement distance ranges from 50mm to 500mm, making it suitable for measuring various rotating objects. Additionally, the tachometer uses a 6MHz quartz crystal oscillator as the time base, with automatic range switching, and is powered by 4×1.5V UM-3 batteries or an external DC 6V stabilized power supply.
