RIKEN RRL系列精密丸型水準(zhǔn)器
日本理研RRL系列丸型水準(zhǔn)器是精密工業(yè)測量領(lǐng)域的經(jīng)典產(chǎn)品，包含1828/2030/2538/2020/2420等多種型號。該系列采用獨特流體阻尼技術(shù)，氣泡移動平穩(wěn)流暢，可實現(xiàn)0.02mm/m至0.05mm/m的靈敏度范圍，滿足不同場景下的精度需求。圓形外殼經(jīng)特殊陽極氧化處理，表面抗刮擦性能較傳統(tǒng)工藝提升約40%，有效延長產(chǎn)品使用壽命。
其核心玻璃管選用硼硅酸鹽材質(zhì)，具備優(yōu)異的熱穩(wěn)定性，在-20℃至+60℃環(huán)境中仍保持穩(wěn)定工作狀態(tài)。內(nèi)部填充液采用低粘度環(huán)保配方，氣泡對比度較常規(guī)產(chǎn)品提高30%，即使在光線不足的施工現(xiàn)場也能清晰辨識。根據(jù)型號差異，產(chǎn)品直徑覆蓋28mm至38mm區(qū)間，適配各類機械設(shè)備安裝、建筑基礎(chǔ)調(diào)平及精密儀器校準(zhǔn)等應(yīng)用場景。
人體工學(xué)外殼設(shè)計采用雙層防滑紋路，握持穩(wěn)定性較傳統(tǒng)水準(zhǔn)器提升約25%。多角度觀察窗口支持水平、垂直及傾斜位置檢測，部分型號內(nèi)置輔助刻度線系統(tǒng)，便于快速判斷微小偏移量。產(chǎn)品通過結(jié)構(gòu)優(yōu)化使重量減輕15%，特別適合攜帶至高空作業(yè)或狹小空間使用。
該系列產(chǎn)品自上市以來已在全球50余個國家和地區(qū)投入使用，其可靠性在軌道交通設(shè)備安裝、精密機床調(diào)試等領(lǐng)域獲得廣泛認(rèn)可。RIKEN理研持續(xù)優(yōu)化生產(chǎn)工藝，確保每件產(chǎn)品在出廠前均通過24小時連續(xù)穩(wěn)定性測試。
RIKEN RRL Series Precision Round Spirit Levels
The RIKEN RRL series round spirit levels, including models 1828/2030/2538/2020/2420, represent Japanese engineering excellence in industrial measurement. Featuring proprietary fluid damping technology, the bubble moves with exceptional smoothness, delivering sensitivity from 0.02mm/m to 0.05mm/m for diverse operational requirements. The anodized aluminum housing demonstrates 40% higher scratch resistance compared to conventional finishes, ensuring extended service life.
Constructed with borosilicate glass tubes, these levels maintain measurement consistency across temperature variations from -20℃ to +60℃. The low-viscosity eco-friendly filling fluid enhances bubble visibility by 30%, providing clear indication even in low-light conditions. Available in diameters ranging from 28mm to 38mm, the series accommodates various applications including machinery alignment, construction leveling, and scientific instrumentation calibration.
Ergonomic housing with dual-layer anti-slip grooves improves grip stability by 25%, while multi-angle viewing windows allow horizontal, vertical, and tilt measurements. Selected models incorporate auxiliary scale lines for rapid micro-deviation assessment. Weight-reduction design (15% lighter than standard models) makes them ideal for overhead operations and confined spaces.
Deployed in over 50 countries, these levels have proven their reliability in rail system installation and precision machine tool calibration. RIKEN s rigorous 24-hour endurance testing protocol ensures consistent performance for every unit before delivery.
