Wireless Tilt, Temperature & Vibration Sensor

A fully sealed, battery-powered edge sensor that measures three-axis tilt, acceleration, vibration frequency, vibration amplitude and temperature, then uploads event-aware data over NB-IoT or 4G — built for structures where a simple tiltmeter is not enough.

SCST-WV02 wireless tilt temperature and vibration sensor with sealed dome housing

Overview

Tilt trend, vibration event and temperature context in one timestamp

SCST-WV02 combines a three-axis MEMS accelerometer, magnetometer, cellular communication, battery power and a sealed polyurethane housing. It reports routine long-term tilt changes, but can also wake on tilt or vibration events and capture high-frequency waveform features for structural health assessment.

✓
Five measurement elements
Tilt, acceleration, vibration frequency, vibration amplitude and ambient temperature are acquired by one device.
✓
Scheduled + triggered reporting
Routine low-power monitoring is paired with event-triggered high-frequency sampling when tilt or vibration changes.
✓
No field wiring
NB-IoT / 4G communication and battery operation fit bridges, towers, slopes and outdoor structures where cabling is expensive or fragile.
✓
IP68 sealed dome housing
High-strength aging-resistant polyurethane housing with a bolt-down base for harsh outdoor natural environments.

How it works

A Low-Power Watch Mode with High-Frequency Event Capture

The sensor normally stays in a reduced-rate watch mode. When scheduled acquisition is due, or when tilt or vibration is detected, it switches to working mode, samples at high frequency and extracts vibration-domain features using FFT.

The same device supports slow structural-trend monitoring and fast event capture. FFT converts the vibration waveform into dominant frequency and amplitude, so alarms can be based on motion signatures rather than tilt alone.

SCST-WV02 time-domain vibration waveform and FFT spectrum output

Data output

From waveform to usable engineering indicators

For each acquisition period, SCST-WV02 can provide tilt, acceleration, vibration frequency, vibration amplitude, temperature, battery state and position metadata. The cloud platform then binds the data to measurement points, thresholds and project drawings.

1
Time-domain waveform
Captures event amplitude over time, useful for judging impact, short-term disturbance and vibration duration.
2
FFT frequency spectrum
Extracts dominant frequency and amplitude, turning raw vibration into structural-health features.
3
Temperature-linked interpretation
Temperature is recorded with the same device, making it easier to separate thermal effects from true motion.

Applications

Where SCST-WV02 Adds Value Beyond a Tiltmeter

Choose SCST-WV02 when rotation, vibration and temperature need to be interpreted together, or when a remote point must operate without cabling or external power.

Building safety

Building Tilt & Vibration

Tracks slow tilt while capturing short vibration events from construction, demolition or traffic disturbance nearby.

Tower assets

Transmission & Telecom Towers

Cable-free tilt and vibration monitoring for unpowered outdoor towers, with IP68 protection and battery operation.

Bridge structures

Bridge Tilt Monitoring

Combines pier or deck tilt trends with vibration frequency signatures under traffic and wind.

Geohazards

Slope and Rockfall Warning

Low-power remote points can be deployed on unstable blocks or protection structures where wiring is impractical.

Outdoor monitoring

Unattended Outdoor Sites

Sealed housing and cellular upload support long unattended monitoring without sunlight or grid power.

Structural health

Event-Based Safety Assessment

Dominant frequency, amplitude and tilt change help distinguish normal environmental vibration from abnormal structural response.

Installation & cloud

Bolt Down, Bind, Set Thresholds

SCST-WV02 is designed for simple civil installation. The important engineering work is choosing a rigid mounting point, binding the device correctly and setting thresholds that reflect the structure's risk model.

Field installation checklist

1
Install on a rigid structural surface
The bolt-down base must couple directly to the monitored member, not to loose render, tiles or temporary fixtures.
2
Align the sensitive axes
Mark the monitored direction before drilling; record the initial tilt and installation orientation as the baseline.
3
Bind network and device ID
Choose NB-IoT or 4G before delivery, then bind the point in the cloud automation-management page.
4
Set rate and cumulative thresholds
Use control indicators for tilt rate, cumulative tilt and vibration-event alarms per point.

Cloud workflow

✓
Project overview
Project details, location, stakeholders and remarks are maintained in one project record.
✓
Monitoring cloud map
Measurement points are placed on drawings or maps, with alarm status visible directly on the project view.
✓
Data summary & analysis
Tilt, vibration and temperature series can be filtered by time, form type and measurement zone.
✓
Daily reports and automation status
Automated points feed daily reports and device-status management for O&M teams.

FAQ

Field Questions, Straight Answers

How is SCST-WV02 different from a normal wireless tiltmeter?

A normal wireless tiltmeter focuses on slow tilt change. SCST-WV02 adds acceleration, vibration frequency, vibration amplitude and temperature, so it can capture sudden vibration events and provide context for whether a tilt change is structural or environmental.

When should I choose SCST-WV02 instead of the tiltmeter series page product?

Choose SCST-WV02 when vibration or impact matters: bridges under traffic, towers in wind, buildings near construction, slopes with block movement, or remote outdoor points where event-triggered reporting is valuable. For pure long-term low-frequency tilt, the standard tiltmeter series is usually enough.

How long does the battery last?

With the non-rechargeable Li-SOCl2 battery, operating life is up to 36 months at 4 acquisitions per day. The rechargeable lithium version runs up to 12 months. High-frequency event triggers, shorter reporting intervals and weak network coverage will shorten life.

Does it need sunlight or external power?

No. The battery-powered configuration is designed for sites without sunlight and without external power. If the rechargeable version is selected, USB-C charging is available at 5 V.

Which network should we choose: NB-IoT or 4G?

NB-IoT is usually preferred for low-power sparse reporting where coverage is stable. 4G is preferred when event data, denser uploads or broader operator coverage are more important. The network mode is selected before delivery.

Can it replace a professional vibration analyzer?

It is a structural monitoring sensor, not a lab vibration analyzer. Its strength is unattended long-term monitoring, triggered reporting and 0.1 Hz / 200 Hz vibration feature extraction at engineering points. For machinery diagnostics or very high-frequency vibration, use a dedicated vibration analyzer.
