Elastisense DS Sensors

High accuracy, high durability IP68 displacement measurement


Twist it, bend it, stretch it, the DS-Sensor will cope and will continuously deliver data, even in the most hostile environments.


DS Sensors

DS-sensors all consist of an extremely strong, durable and very efficient stretch sensor. The sensor is fully encapsulated in high grade silicone rubber with embedded electronics, and this makes it extremely durable and resistant to external influences, such as rain, snow, dust, heat, cold, dirt or other environment and weather-related obstacles.

The stretch sensor technology combined with the silicone rubber encapsulation makes the DS-sensors fully bendable in all directions as well as tolerant to over-stroke and considerable misalignment.

The perfect alternative to LVDT sensors and crack gauges.

DS Sensors are available in range of options.

  • Size : from 5mm to 250mm in measurement range.

  • Output : 4-20mA, 0-5V, 0-10V, RS-232 or RS-485.

  • Fixings : single of double fixing points at either end.

  • Cable length : 1m, 3m or 10m

  • Cable termination: flying lead, M8 6pin, M12 6 pin

  • Power supply: 2.5V-5.25V or 12V-24V

  • Temperature: -40°C to +85°C or -40°C to +105°C

  • Body colour: black, white or grey

*These are our standard options. Addition options are available on request and do incur an additional price premium. 

How do they work?

DS Sensors measure the changes in distance between the fixing points at either end. 

The sensors itself updates the reading 1,000 times per second. In order to capture these readings a DS Sensor needs to be connected to a data logger or data communication device. 

DS Sensors are quick and easy to connect to a wide range of wireless remote monitoring systems including

  • Ackcio

  • WorldSensing

  • WiSen

  • Trimble

  • GeoSense

  • Move Solutions

  • Monnit

  • iBridge

and many more...​

Connecting the analogue version of the DS Sensor requires two cables to provide power to the sensors, and two cables to receive the readings from the sensor. 

The limitations on how frequently the readings are captured will be determined by the data logger or communication device the DS Sensor is connected to. Most wireless remote data loggers can only capture readings at 2-5min intervals at their fastest. 

To capture the dynamic readings from the DS Sensor, it will need to be connected to a data logger that is cable of capturing the continuous reading adjustments the DS Sensor provides. 


What can they be used to monitor?

Due to their robust, flexible nature, their high sampling rate and their ability to be integrated with many remote monitoring systems, DS Sensors can be used in a wide variety of applications.
