TORQUE SENSOR CALIBRATION KITS
Sensing Systems designs and manufactures Calibration Kits to meet torque calibration requirements up to 360,000 lb.in capacity. The kits may be portable or permanent installations and are designed to fit the customer facilities. Torque Calibration Kits are categorized into load cell or weight based systems. Selection of the type of kit is a function of the maximum calibration torque needed to complete the calibration. All torque kits require a loading arm, weights or load cells, weight pans, and a calibration stand. Depending on capacity, some kits require hydraulic jacks and pumps to generate the required loads. Most torque Calibration Kits and certainly all portable units are of the calibrated weight variety. Load cell type kits can be portable, but are usually permanent installations due to the size of the equipment needed to apply and react the required loads.
CALIBRATED WEIGHT KITS
Calibrated weight kits are the most common. All portable kits are of this type. They consist of a double ended loading arm, calibrated weights, and a weight pan. This kit is completely mechanical with no need for digital displays. Calibrated weight kits range in capacity from 1 lb.in to 50,000 lb.in. All weights are calibrated with NIST traceability.
The double ended arm is attached to the torque sensor. The weight pans are hung from the ends of the arm and calibrated weights are placed on one of the pans to apply calibration loads. The actual torque load is the product of the calibrated weight value times the distance from the center of the arm to the weight pan support point. Loading one or the other weight pan applies clockwise and counterclockwise calibration loads.
torque sensor KITS
Torque sensor kits are used for torque capacities exceeding 50,000 lb.in. These kits include loading arms, load cells, digital indicators, hydraulic pumps, and jacks. They are custom made for the application and location of the facility where they are used. The torque is the product of the load cell reading times the distance from the center of the arm to the load cell attachment point. Two load cells and jacks are used to allow for clockwise and counterclockwise operation.
