Compression Force Sensor DK3

Compression Force Sensor DK3

Compression Force Sensor DK3

Product catalog summary
Overview: The DK3 series compression force load cells are designed for use in confined spaces, featuring a compact cylindrical form and small dimensions. Constructed from stainless steel and rated at IP 67, these sensors are suitable for wet conditions in machinery and equipment.
Design and Functionality: The load cells utilize a single sensor element optimized through finite element analysis, ensuring uniform dimensions across all models. They operate on either the shearing or compression principle, depending on the nominal force rating. Strain gauges on the sensor body capture forces, and a measuring amplifier like the HAEHNE MV125 processes the signals.
Specifications: The DK3 series offers nominal force ratings from 1 to 50 kN, with a maximum operating force of 160% of the nominal force. The nominal rating is 1.5 mV/V, with a combined error of 0.5%. The sensors operate within a temperature range of -10 to +70°C and have a nominal ambient temperature range of +10 to +60°C. The strain gauge bridge resistance varies with the force rating, being 350 Ω for 1-2 kN and 700 Ω for 5-50 kN models.
Installation and Accessories: The load cells come with a 5 m PVC cable and options for axial or plug connections. They are easy to mount due to the radial cable entry and compact design. Accessories include a load button and options for use in explosive areas.
Ordering Information: An example order code is DK3-1k-TF, indicating the type, nominal force, and variant/option. The sensors are available with additional options for specific applications.

Compression Force Sensor DK3-1

Scope of Supply Force sensor with 5 m cable (PVC), axial output with cable connection T: cable gland, straight; load button Variant N2: plug connection, straight, M12, moulded Additional Option F: For use in explosive areas, incl. J-Box Special Features • Minimum space requirement due to compact design Simple mounting • Nominal force ratings from 1 up to 50 kN • Made of stainless steel Ordering example: DK3-1k-TF Type Nominal force Variant / Option The cylindrical form and small dimensions of the compression force load cell series DK3 make them especially suitable for confined spaces. The completely enclosed stainless-steel design with the protection class IP 67 is able to withstand wet conditions in machinery and equipment. The screw top ensures an optimal force path. The sensor consists primarily of a single sensor element designed and optimized with finite element analysis. As a result all sensors have the same dimensions. The load cells with nominal force ratings of 1 and 2 kN function according to the shearing principle, the other according to the compression principle. Strain gauges applied to the active areas of the sensor body capture the acting forces. A measuring amplifier e. g. the HAEHNE MV125 is available for the voltage supply to the full bridge and the processing of the measuring signals. The signals at the output terminals of the amplifier are proportional to the acting compression force. They can be digitally displayed or used as instantaneous values in a control loop. The radial cable entry facilitates simple mounting of the load cell to machine frames.
