Measurement channels

Each SquareBug® comes equipped with 12 measurement channels, among which four are designated for strain measurements. These channels are versatile and can be configured for synchronous quarter, half, or full bridge operations. Notably, the SquareBug® features a triaxial accelerometer capable of delivering precise measurements up to ±16 g, with an impressive sampling rate of 1,665 Hz per channel. Furthermore, the integration of a triaxial gyroscope function enables accurate measurements of rotational movements across three dimensions. In addition to these features, the SquareBug® is equipped with an internal temperature sensor as a standard component, and for added flexibility, an extra channel is available for external temperature measurements as an optional feature.

Remote Access from the Global Data Network (GDN®)

Accessing the gateway and SquareBug® details is facilitated through the utilisation of the Global Data Network (GDN®). This platform ensures seamless connectivity and enables the convenient remote viewing and interrogation of all industrial asset monitoring data through a standard web browser interface. Users can monitor, manage, and analyse the system's performance and the collected data from virtually any location with internet access.

Events and Time Domain Logging Modes

The SquareBug® is designed to capture crucial events through a predefined trigger, constituting its core functionality. This trigger operates by detecting zero-to-peak or peak-to-peak differences within a system to record anomalies, especially during startup and stopping operations. Notably, smaller magnitude measurements are not discarded; instead, they are collected by the Rainflow counting and time-at-level feature, facilitating direct application of fatigue analysis to targeted components. The SquareBug® can also be used for continuously logging of all or selected channels to suit client requirements.

Wireless Connectivity for Simplicity

SquareBug® eliminates the need for cumbersome wires and cables by wirelessly communicating via short-range radio (up to 50m). This simplifies installation and reduces the clutter commonly associated with traditional wired sensor systems, providing enhanced flexibility and deployment convenience for remote or unattended data logging.

Simple Installation

SquareBug® installation package includes a comprehensive standard installation procedure. Typically, a magnetic base is used to attach the SquareBug® to surfaces with slow rotational motion or those that remain static. In more challenging environmental conditions, structural adhesive provides an alternative for secure attachment.

Long Battery Life

The SquareBug® is engineered for long-term performance, with its internal battery boasting a typical lifespan of up to 4 weeks with the possibility of extended battery life, reducing the frequency of battery replacements.

How SquareBug® is utilised in optimising industry.

Precision Strain Gauging

Industrial Asset Monitoring

The SquareBug® can be utilised by many industrial sectors where data is required to be harnessed from harsh environments. As standard the wireless sensor system can be mounted on slowly rotating or static components, or otherwise can be repackaged into a bespoke housing to allow seamless integration with monitored assets. The SquareBug® has been used in industry to find operational anomalies such transients including temperature, vibrations and strains.
