Harsh Environments / Long Term Deployment

For applications in harsh environments and when access for maintenance is not always practicable, then vibrating wire strain gauges and load cells are better suited than standard bonded gauges. A range of vibrating wire interfaces are available and these support many different manufactures load cells and strain gauges.

Weldable VW Strain Gauge
A complete Silo weight monitoring solution to suit many different applications can be created and supplied using the AquaLOG range of instrumentation. The systems are modular in construction and can contain local displays or be connected to the directly to the Internet for remote monitoring applications.  

Many different sensor inputs are supported as standard such as resistive and vibrating wire load cells and strain gauges as well as our own intelligent liquid level sensors can be combined into a single solution.

Typical Application

The examples below demonstrates a typical minimum specification installation. The package shows the AquaLOG interface and display used to present results to an operator. A minimum specification solution will use a pair of single channel strain gauge interfaces for bonded gauges to the silo or to drive load cells. For harsh environments then vibrating wire sensors can be used.

User Defined Configuration & Calculations

The AquaLOG interface undertakes all of the sensor linearisation and mathematical calculations needed to obtain the total load from the sensors. A display unit shows the total load in the silo or can be used to display parameters from any of the sensors.
