Product overview and engineering role
The dual-axis inclinometer watches pitch and roll on structures, slopes, bridges, tunnels, and large machines. A low-noise accelerometer and temperature compensation keep the zero stable for a long time across wide temperature and vibration. The output can feed SCADA, a geohazard platform, or a building structural-health system.
SimtoLink supplies a mounting-base note, an initial zero procedure, and a threshold-policy template. Uplink is LoRa or RS485, by order code. Volume jobs can change the ingress rating and cable length, and can add help with a third-party metrology submission.
Reliability and site fit
The unit has passed the relevant CE and FCC tests. Ports include surge and reverse-polarity protection. Reinforced grounding and a zoned layout cut ground-loop and common-mode noise. Outdoor and coastal sites can specify a higher ingress rating and a corrosion-resistant coating.
Software accepts a batch parameter import, threshold rules, and event or waveform capture where the model includes them. Configuration and firmware can move over the air. Close acceptance on site in three steps: power-on self-test, time sync, and a sample check. Metering or safety use can add a third-party metrology submission and type-test documents.
Key hardware parameters
Use this table for the typical order when you write a selection note or a bid clause. A wider span, redundant supply, or an intrinsically safe build is quoted separately, with the hardware specification and the commissioning guide. Sibling order codes can shift slightly; follow the nameplate and the papers packed with the sensor.

Typical applications
Three ways this sensor is usually installed, useful when you are still selecting and when you prove the link to the platform:
Slopes and geohazards
On landslide masses, retaining walls, and tunnel portals, with rainfall and displacement for a joint warning. Low-power backhaul and threshold-triggered waveform capture.
Bridges, tunnels, and structural health
Watches the attitude of piers, beams, and bearings. Data goes to the SHM platform for the annual inspection and a load-test comparison.
Construction machinery and gantry cranes
On the boom, the slewing platform, or the rail foundation, for anti-tip monitoring, an attitude interlock, and remote inspection.
Installation, grounding, and maintenance
- Confirm the supply range and polarity before the breaker is closed. Meter the bus if the drawing is unclear.
- Run communications on shielded twisted pair, bond the shield at one end only, and keep it off long parallel runs with power cable.
- Prove two-way access and a threshold trip in the lab before the sensor leaves for site.
- Outdoors, give water a way out and air a way through, inspect the seal faces, and hold the lightning earth to the local limit.
- In continuous service, sample-check the sensor and archive logs every 24 months.
Ordering, documentation, and support
The pack includes the hardware specification, an outline drawing, a wiring table, and a sample project. A volume order can add a sample review and a resident factory inspection. Warranty and calibration stay with the contract and the documents that travel with the sensor.
