Tiltmeter Series倾角计系列
Surface-tilt monitoring for buildings, bridges, towers, tunnels and heritage structures. Wireless LoRa / NB-IoT variants run 2–5 years on battery; wired RS485 variants deliver 0.0005° resolution with uninterrupted acquisition. 面向建筑、桥梁、铁塔、隧道与古建筑的表面倾斜监测。无线 LoRa / NB-IoT 版本电池续航 2–5 年；有线 RS485 版本分辨率达 0.0005°，不间断连续采集。
One series, every tilt-monitoring scenario 一个系列，覆盖全部倾斜监测场景
The RTILT / RWIN tiltmeter series measures dual-axis surface tilt relative to the horizontal plane. Two sensing technologies and two communication architectures combine into a family that fits everything from a remote, unpowered tower to a continuously powered tunnel — and pairs naturally with our hydrostatic settlement gauges. When vibration events and temperature need to be captured with tilt, use the RWIN030 wireless tilt + vibration sensor. RTILT / RWIN 倾角仪系列测量结构表面相对水平面的双轴倾角。两种传感技术与两种通信架构灵活组合，从无供电的偏远铁塔到持续供电的隧道均可覆盖，并常与静力水准沉降监测在同一结构上配套部署。若需要把振动事件、温度与倾角一起采集，请使用 RWIN030 无线温振倾角一体设备。

A Bubble in Liquid vs a Mass on Springs液中气泡 与 弹簧上的质量块
An electrolytic tiltmeter seals a conductive electrolyte and an air bubble inside a vial with three platinum electrodes — one common, two differential. As the housing tilts, the bubble shifts and the length of liquid between the two outer electrodes changes, unbalancing their impedances R₁ / R₂. AC excitation prevents polarization, and a Wheatstone bridge turns the differential conductance directly into sin θ. A MEMS tiltmeter instead suspends a silicon proof mass on micro-springs: gravity displaces it by x = m·g·sin θ / k, and differential comb capacitors read the displacement as θ = arcsin(aₓ / g). 电解液倾角仪在密封管腔内封装导电电解质溶液和一段气泡，腔内伸入 3 根铂电极——一公共、两差分。外壳倾斜时气泡偏移，两差分电极间的电解液柱长度变化，阻抗 R₁ / R₂ 失衡；交流激励避免极化，惠斯通电桥将差分电导直接转换为 sin θ。MEMS 倾角仪则用硅微弹簧悬挂一个检验质量：重力使其位移 x = m·g·sin θ / k，差分梳齿电容读出位移，θ = arcsin(aₓ / g)。

MEMS and Electrolytic: Two Physics, One Honest RecommendationMEMS 与电解液：两条物理路线如何选
These are not a high/low configuration of the same product — they are two different physical principles. We recommend by monitoring period and site vibration, not by price.两者不是同一产品的高低配，而是两种不同的物理原理。我们按监测周期与现场振动条件推荐路线，而不是按价格。

Rigid mounting matters刚性安装是前提
The base must be rigidly bonded to the structure itself — never to render, tiles or uncured concrete. Our installation guide eliminates "the sensor shaking itself" false signals.基座必须与被测结构刚性连接，严禁安装在涂料、瓷砖或未固化水泥上。我们的安装规程杜绝"传感器自己晃"的伪信号。
Temperature compensation built in内置温度补偿
Electrolytic sensors are temperature-sensitive; without compensation, day-night cycles masquerade as displacement. Compensation is mandatory, not optional, in our designs.电解液传感器对温度敏感，不温补会让昼夜温差伪装成位移变化。在我们的设计中温补是强制项，而非可选项。
Choose by decades, not by quarter按几十年选型，而非眼前价格
For a 30-year heritage program, MEMS will drift; electrolytic will not. We state the physical boundary up front so the right choice is obvious before installation — not five years after.面向 30 年古建项目，MEMS 必然漂移，电解液则不会。我们在选型阶段就讲清物理边界，而不是让客户五年后才发现问题。
Accuracy Is Decided at the Mounting Surface精度在安装面上就已决定
A loosely coupled base makes the most expensive sensor worthless. These are the steps our field manual enforces on every installation.基座虚连会让再贵的传感器都失真。以下是现场手册在每次安装时强制执行的步骤。
- 1Fix the base rigidly to the structure itself基座与被测结构刚性连接
The mounting base must connect rigidly to the load-bearing structure being measured — base rigidity matters even more than sensor accuracy.安装基座必须与被测结构本体刚性连接——基座的刚性比传感器本身的精度更重要。
- 2Reject weak surface media拒绝虚弱的表层介质
Never install on surface render or paint, on tiles, or on uncured concrete. A base on these media produces "the sensor shaking itself" false signals — the most common field mistake.严禁安装在表层涂料、瓷砖或未结固化的水泥上。装在这些介质上会产生"传感器自己晃"的伪信号——这是现场最常踩的坑。
- 3Align the measurement axes对准测量轴向
The instrument measures dual-axis (A / B) tilt relative to the horizontal plane — align the axes with the directions the structure needs monitored.仪器测量 A 轴 / B 轴相对水平面的双轴倾角——安装时将轴向对准结构需要监测的方向。
- 4Shade from sun, enable temperature compensation遮阳防晒，启用温度补偿
Sun-exposed installs show day-night cyclic swings. Fit a sun shade where needed; on electrolytic units, temperature compensation is mandatory, not optional.受日晒的安装点会出现昼夜周期性波动。必要时加装遮阳罩；电解液版本的温度补偿是强制项，而非可选项。
- 5Wire, verify and baseline接线核验，记录初值
Wired units take DC 7–12 V with RS-485 / 4–20 mA output — verify polarity with a multimeter (a reversed line reads zero). Record initial values, then sync tilt and temperature time series to the cloud with threshold alarms.有线版本供电 DC 7–12V，输出 RS-485 / 4–20mA——用万用表核验极性（接反读数为零）。记录初值后，倾角与温度时序同步上云并设置阈值告警。
Where the Tiltmeter Series Works倾角仪系列的典型应用
Tilt rarely tells the whole story alone — on most structures it is paired with settlement monitoring. See the combined selection guide on our settlement page.倾斜往往不是孤立指标——多数结构会同时布设沉降监测。完整选型矩阵见沉降监测页面的选型指南。
Dilapidated Buildings危房监测
Cable-free installation and multi-year battery life make city-wide aging-building alarm networks practical and affordable.免布线安装与多年续航，让城市级危旧房屋预警网络切实可行、成本可控。
Tower Tilt铁塔倾斜
Transmission and telecom towers at remote, unpowered sites — IP68 housings survive all-weather outdoor exposure for years.输电与通信铁塔多处于无供电偏远场地——IP68 外壳支持多年全天候户外运行。
Bridge Tilt桥梁倾斜
NB-IoT cellular transmission gives more reliable long-distance reporting for piers, pylons and approach structures.NB-IoT 蜂窝传输为桥墩、桥塔与引桥结构提供更稳定的远程数据上报。
High-Support Formwork高支模监测
During concrete pours, 0.003° accuracy and uninterrupted acquisition catch dangerous formwork movement in real time.混凝土浇筑期间，0.003° 精度与不间断采集实时捕捉支模体系的危险变形。
Tunnels隧道监测
Stable site power supports continuous lining-tilt acquisition over the full construction and operation period.现场稳定供电支持隧道衬砌倾斜在施工与运营全周期的连续采集。
Heritage Structures古建筑保护
Decade-scale preservation programs for historic towers and timber structures demand 1×10⁻⁸ rad-class long-term stability.古塔、木构等文保项目需要数十年监测周期，1×10⁻⁸ rad 级长期稳定性不可或缺。
