Submersible S-Beam Load Cell | IP68 Waterproof | DBBSUB
Hermetically Sealed for Long-Term Submersion up to 2 Metres/0.2 Bar Applied Measurements DBBSUB submersible S-Beam load cell is ideal for tension and compression measurement in situations involving permanent submersion in water. They are hermetically sealed to IP68 to a depth of 2m/0.2bar making them ideal for flood susceptible locations, submersible and hydrostatic applications. The permanently submersible s-beam load cell has a dual bending beam design to ensure inherently high accuracy and enables us to guarantee performance well within specification. Our DBBSUB permanently submersible load cell can be supplied with specialised rod end bearings further guaranteeing the transducer’s optimum performance. For fast and simple installation they can be supplied with custom designed mounting plates and fixtures. If you require an IP67 rated S-Beam load cells with capacities of less than 50kg or greater than 10,000kg, our DBBSM series of S-Beam load cells covers load ranges from 0-1kg (10N) up to 0-30,000kg (300kN). Meanwhile, if you need to fit into a restricted space, Applied Measurements DBBSMM range of miniature S-Beam load cells will fit the bill.
