SST300 High-Performance Industrial Inclinometer

SST300 HIGH-PERFORMANCE INDUSTRIAL INCLINOMETER

OVERVIEW

The Vigor SST300 is a high-performance inclinometer engineered for reliable static tilt measurement in precision industrial, infrastructure and defense applications. Based on MEMS accelerometer technology, it combines systematic reliability design, EDA/CAE simulation, controlled manufacturing and multidimensional calibration. Each unit is tested and compensated for temperature drift, nonlinearity, cross-axis error, zero offset, repeatability, hysteresis and installation alignment before shipment.

The result is a robust, application-ready sensor that maintains high accuracy after installation. Proprietary vibration-suppression technology can be adjusted on site to improve measurement stability in mechanically noisy environments, while a modular platform supports diverse communication interfaces, housings, cables and connectors.

MEASUREMENT PERFORMANCE

SST300 performance is specified by measurement range. At 25°C, combined absolute accuracy is:

- ±5° range: ±0.01°
- ±10° range: ±0.015°
- ±15° range: ±0.02°
- ±30° range: ±0.04°
- ±45° range: ±0.06°
- ±60° range: ±0.08°

Comprehensive accuracy accounts for absolute linearity, cross-axis error, zero offset, repeatability and hysteresis. Cross-axis error is ±0.1% FS. Repeatability and hysteresis are both ±0.0025°. Zero offset is ±0.005° for ranges up to ±30° and ±0.008° for wider ranges. Resolution is 0.0025°, zero power-on repeatability is ±0.008°, and long-term stability is ≤0.02°.

INSTALLATION AND TEMPERATURE COMPENSATION

The SST300 accepts input-axis misalignment of up to ±4.0° on the ±5° model, with compensated limits matched to each wider range. This feature helps correct mounting deviation and improves effective measurement accuracy after installation.

An integrated temperature sensor covers -50 to +125°C with ±1°C accuracy. The inclinometer operates from -40 to +85°C and may be supplied with application-specific temperature-drift compensation profiles for different ranges and operating windows.

RUGGED CONFIGURATION OPTIONS

Special housing options support demanding installations, including high-temperature exposure, underwater use, nuclear-radiation environments, beam-mounted applications, hazardous areas and low-temperature startup. Available cable and connector choices include aviation connectors, reinforced shielded cables, high-temperature cables, armored cables, watertight assemblies, angled plugs, explosion-proof assemblies, pigtails, USB, Ethernet and CAN/CANopen cables.

APPLICATIONS

The SST300 is designed for precision instruments, vessels, military equipment, security systems, railways, civil engineering, construction machinery, bridges, factory automation, scientific research and teaching. Its combination of calibrated accuracy, installation compensation and configurable industrial connectivity makes it especially suitable for projects where dependable long-term angle data is more important than high-speed dynamic response.

MODEL SELECTION

Customers can specify single-axis or dual-axis measurement, range, output interface, housing, connector and temperature-drift compensation. Select the ±5° model when the highest 0.01° combined absolute accuracy is required. Wider ranges provide greater measurement coverage with accuracy values defined for each range in the performance specification.
