Strain sensors DA40 / DA54

DA40 / DA54: high resolution strain sensors for force- and load control.
Measuring range ±0,1...±1000 µm/m

DA40	DA54-PUR	DA54-M12

The areas of application for the strain sensors DA40 and DA54 are the high-resolution acquisition of forces and deformations on massive components e.g. of presses, lifting tools, tanks, steel supports, bridges as well as on connecting rods or pedestals of production machines.

The retrospective installability make these strain sensors into universal, retro-fittable sensors for monitoring force and load. These strain sensors are durable and resistant to oil and moisture.

The most favorable installation position is lateral to the direction of loading. The forces are then transmitted through the housing. Up to an strain of 1000µm/m, however, assembly longitudinal to the direction of the stress is possible without any limitation in the accuracy.

The strain sensors DA40, DA54 and DadX are excellently suited for static and dynamic measurements.

The strain sensors DA40 and DA54 only differ from each other in their dimensions and the fasteners (M4 or M6).

The strain sensors DadX consist of two half-shells, which are mounted on pillars. They are available for diameters from 50mm to 250mm.

The sensor DA54 is also available without a sink for mounting with concealed studs.

The same performance features are achieved with these strain sensors in their robust and installation-friendly aluminum housing as with the direct application of strain gages . This includes a high resolution, very low drift symptoms and the possibilities for both static and dynamic measurement. The strain sensor contains a completely wired strain gage, which, when the strain sensor is being screwed on, is pressed on the component to be glued by a specially shaped pressing mechanism. The housing serves as a mounting frame for the strain gage application.

The surface of the component must be ground and cleaned before screwing on the strain sensor in the area of the strain gage. The strain gage is permanently protected against moisture by means of a special, oil-resistant seal. The null balancing of the strain gage is carried out after the installation of the strain sensor by the strain gage measuring amplifier GSV-2. strains from 0.1?m/m onwards can be displayed. This corresponds to a mechanical stress of about 0.02N/mm2 on a component surface of steel. With the combination of strain sensor and measuring amplifier GSV-2, switching thresholds from about 1?m/m (corresponding to 0.2N/mm2) onwards can be monitored, if a null balancing is carried out periodically. For applications in weighing technology, an strain range of at least 30µm/m (6 N/mm2) is recommended, in order to achieve as low a drift as possible.
