Force Calibration

Our calibration offers calibration services for most torque and force instruments. The calibration provided by our torque and force lab uses test equipment traceable to national institute of standards and technology (nist). Available calibration types for torque and force equipment are:

Z540-1 traceable calibration with as found/as left datathe instrument is processed in accordance with ansi/ncsl z540-1-1994 standard.The certificate of calibration includes as found and as left data, tolerance and assessment of compliance with the manufacturer’s specifications.
Electronic copies of your calibration certificates are accessible via our web-based portal.

The portal not only provides copies of your calibration certificates but also current asset status, asset history and due date reports for your equipment. Our range of services includes, but not limited to calibration of force gauges, dynamometers, various torque wrenches and torque screwdrivers, torque analyzers, and torque transducers. Our technicians perform calibrations in accordance to documented and controlled procedures to ensure testing meets manufacturer’s specification.

These calibrators incorporate a liquid (oil in most cases), a stirring mechanism and a heating/cooling element. Liquid baths usually have uniform specifications throughout, due to the constant stirring and the liquid being circulated through the bath. Moreover, they are ideal for calibrating odd-shaped or extremely small sensors due to the uniformity of the liquid. A few negatives of liquid bath calibrators are that they cannot be transported to different locations with ease and are stationary, they are difficult to maintain, they get quite messy, and they take longer to reach the desired temperature. The oil/liquid in the bath must be drained and refilled periodically. It is critical to dispose of the liquid carefully.

These calibrators consist of a heating ‘block’, an internal sensor, and control mechanism to reach and maintain the desired temperature range. They do incorporate a heating/cooling element, however, no liquids are used in the process. They are portable due to their structure and are less messy. One of their biggest advantages is that they reach the desired temperature much faster as compared to traditional baths but are less accurate and less stable than them. Technological developments are improving the performance of dry-blocks in terms of accuracy and stability.

Electronic calibrators have the ability to simulate the sensors under test (sut) and provide readout results on the sensor’s performance. The one drawback of electronic calibrators is that the integrity of the sensor is not tested since there is no temperature source to subject the sensor to. On a positive note, they cost a lot less than traditional liquid baths or dry-block calibrators, and are quite portable.

If any instrument was damaged in an accident, if it was dropped hard or if it sustained any kind of injury, you must calibrate it immediately. Events where the instruments sustain damage usually experience a sharp impact that directly affects their readings. Check if the calibration was altered and carry out the necessary calibration procedures.

When you carry out certain assignments, you have to use certified and calibrated test equipment, irrespective of how big or small the project is. When assignments call for such calibration based on project requirements, you must follow it.

Some major projects require extremely accurate measurements. This means that the instruments must be calibrated before the project starts. However, it doesn’t end there. You must calibrate all the instruments that were used after the project comes to an end. Post-project calibration will show you if the testing that you conducted is indeed reliable or not, if the correct and consistent measurements were observed throughout the project.
