Sensor Solutions

Position sensing made easy, is a key term for ElastiSense. We strive to produce high quality sensor solutions that add value to applications within many different business areas, for example; industrial automation, Structural Health Monitoring, Off Road Vehicles and other applications where the going gets tough. We add value in terms of reduced costs for installation, operation, and maintenance as well as valuable data about the status of the application. This can ultimately enable preventive maintenance  in places other sensors cannot be used.

The most important features of ElastiSense products are:

  • Robust– highly resistant to shock, vibration, overload, and misalignment
  • Accurate and repeatable– high accuracy due to capacitive sensing.
  • Versatile– can be configured to different needs in size, range, and electrical output.

DISPLACEMENT SENSORS

The flexible nature of the sensors enables linear and off-axis displacements measurements in all three directions. Our displacement sensor may either be used as a standalone unit or as a part of a system together with other daisy chained sensors. In stand-alone mode the sensor requires 24VDC supply and outputs an analogue current in the range of 4-20mA. The output signal is linearly proportional to the displacement i.e. 4mA corresponds to 0mm and 20mA represents the maximum displacement of the sensor. The sensors are available in 20, 50, and 100mm measurement ranges. Other customized ranges are available upon request.

MONITORING SYSTEM

If your system requires multiple sensors, we recommend ElastiSense Monitoring Systems, containing multiple daisy-chained sensors and a controller to handle communication and data processing. The controller communicates with the sensors over a full duplex RS485 network. The controller receives real-time, synchronised data from the sensors, analyses it, then sends information (signals, data, alarms) to the machine controller, operator, or a supervisory controller.

The controller used for this is a standard, versatile controller from National Instruments, from their cRIO Series. It can be configured to communicate with your system with a protocol of your choice, as there is a wide range of corresponding communication modules available.
