Robust strain sensor for harsh outdoor environment

The weight of construction vehicles can be determined using strain sensors. This enables the loading of dump trucks, for example, to be controlled, avoiding overloading. The robust design of the strain sensors also guarantees reliable measurement results even when used in harsh outdoor conditions in quarries and gravel pits.

Using strain sensors for construction machinery means that vibrations on the placing boom of truck-mounted concrete pumps are dampened. The long-term seal and robust design also guarantee dependable continuous operation on construction sites.
 

Strain sensors are used on cranes to detect loads on supports, arms, or counterweights, for example, and thus prevent overloading or tilting of the cranes. The use of corrosion-resistant materials means that the sensors can be used on harbor cranes without any problems.

Strain sensors also monitor the shaft load of telehandlers. This detects overloading and prevents overturning. The long-term seal and robust design also guarantee dependable continuous operation on construction sites.

When strain sensors are used on wind power plants, loads on the tower or rotor blades are reliably monitored. This ensures that overloads are detected and damage to the wind turbine is prevented. The calculated service life is extended on the basis of the actual loads. The unique sealing design and corrosion-resistant material make the strain sensor ideal for use in offshore wind power plants.

• Sensors remain reliable and impermeable over their entire service life 
• Shock-tested over the entire temperature range to simulate aging effects
• IP 69K protection against ingress of dust and high temperature, high pressure water
