Designed as a smaller and more cost-effective alternative to its established caliTEST calibration device for torque wrenches, Kistler has introduced caliTEST-B. It enables the calibration of torque wrenches or tools with an effective length of up to 1,320mm according to DIN EN ISO 6789.
For years, Kistler has offered the caliTEST, a special calibration device for torque wrenches, to minimise the impact of calibration on ongoing operations. It is a popular option, particularly for larger companies with many torque tools and their own calibration laboratory. However, for medium sized companies or those using a smaller number of tools, such a calibration device is usually not worth the investment. This means they have to send the torque wrenches to specialised laboratories in order to have the calibration carried out there.
Kistler now offers an alternative for this customer group, the caliTEST-B. The small, cost-effective brother of the large laboratory test bench enables reliable calibrations in the range from 2.5Nm to 500Nm. If required, the calibration range can also be extended to 0.2Nm to 1,000Nm. To ensure the safety of bolted connections, specific standards cover both the testing of fasteners and the associated tools. These include DIN EN ISO 6789, which describes the regular calibration of torque wrenches.
Similar to the large calibration device, the caliTEST-B consist of a mounting device for the torque wrench, a drive unit with torque sensor, measuring and control electronics and an evaluation system. Unlike the existing caliTEST, which covers a particularly wide measuring range with several holding devices, the sensors in the caliTEST-B can be exchanged for different torque ranges. An equivalent device for longer tools is available as well. Options include a special holder for the screwdriver-shaped torque wrenches, a barcode reader and a label printer. These latter options allow for checked tools to be quickly recorded and labelled in the system as part of everyday work.
For process reliability, Kistler relies on the convenient CEUS software for the caliTEST-B calibration. The web-based program allows users to integrate individual limit values, specifications and tolerances into the evaluation. In addition, the different values and settings for the respective tools can be easily saved for particularly convenient use. The program then guides the user step by step through the measurement process and generates an individual measurement history for each tool. CEUS automatically saves the test reports so that they are quickly available when needed. To ensure that calibration is carried out quickly and smoothly in accordance with the standards, Kistler offers appropriate user training courses.
