Load Cell Calibration Kits and Torque Sensor Calibration Kits

Several industries such as pharmaceutical, medical, testing, etc. must continuously calibrate their measuring equipment to comply with government regulations. Some companies prefer to have calibration capabilities in-house when their calibration requirements become extensive.  Calibration Kits allow in-house calibration of sensors and provide NIST traceability by recalibrating the traceable standard on a yearly basis.  Sensing Systems Calibration Kits meet all of these requirements by including calibration standards, loading fixtures, procedures, and NIST traceability documentation.  Adherence to regulations and Quality Control (QC) requirements are assured through traceable measurements.  Faulty and/or out of spec equipment can be identified, repaired, or replaced as necessary.

Our Calibration Kits are selected based on measurement type and maximum calibration load.  The measurement type is either Force or Torque.  Maximum calibration loads for force applications range from ounces to 3 million lbs and from 1 lb.in to 30,000 lb.ft for torque applications.

LOAD CELL CALIBRATION KITS (Force Sensor Calibration Kits)

Kits to calibrate load cells or force sensors fall into two categories.  Depending on the highest calibration load, either load cell or calibrated weight kits are used.  Load cell based kits are used for applications exceeding 300 lbs.  Calibration weight based systems are used for applications where the maximum calibration load is 300 lbs or less.

Load Cell Kits

Calibration Kits with a load capacity higher than 300 lbs require a load cell and digital indicator.  These two components are calibrated at the factory as a system.  This system becomes the traceable calibration standard.  The Calibration Kit may also include loading fixtures, operating instructions, calibration procedures, and traceability documentation.  A carrying case is also provided when the size of the components allow it.  A press or other load bearing structure, which the customer usually provides, is necessary to apply calibration loads to the sensor needing calibration.  Sensing Systems may also provide the press.  In some cases the sensors needing calibration are calibrated while installed in its equipment.  Such approach is followed when the equipment can also apply the calibration loads in a controlled manner.  This avoids the cost of downtime and/or assembly and disassembly of the machine where the sensor is installed.

Calibrated Weight Kits FOR LOAD CELL CALIBRATIONS

Sensing Systems supplies weight-based kits for applications where the maximum calibration load is 300 lbs or less.  In certain cases, these kits may go up to 1,000 lbs if the configuration of the sensors needing calibration permits easy loading of the weights.  These kits consist of NIST traceable calibrated weights, weight pan, loading fixtures, calibration procedures, and traceability documentation. The number and value of the weights are selected based on the highest calibration load.  The weight selection criteria require a minimum of five equally spaced loading intervals.  Unlike the load cell based Calibration Kits, weight based kits do not require electronic components to display the applied load.  All weights are stamped with their weight value for ease of identification.

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.

CALIBRATION KITS FOR PHARMACEUTICAL TABLET PRESSES

Sensing Systems designes and manufactures Tablet Press Calibration Kits to fulfill regulatory requirements in the Pharmaceutical Industry.  Tablet presses producing tablets are instrumented with a series of sensors that monitor compression and ejection forces.  These sensors must be calibrated to comply with cGMP and Quality Control requirements.  The typical calibration interval is one year.  Six months intervals are also common.  

 

Most Tablet Press Calibration Kits are load cell and calibrated weight based systems.  They typically contain two or more of the following components:

  •  Load Cells: 50 kN and 2.5 kN
  •  Digital Indicator
  • Calibration Weights: 50 grams
  • Loading Fixtures and attachments
  • Carrying Case
  • Documentation including Procedures, Operating

Instructions and NIST Traceability Calibration loads are applied with the sensors installed in the press.  Tablet presses are capable of applying loads in conjunction with the loading fixtures and attachments.  The calibration procedure conforms to industry standards and directs the user to proper documentation practices.
