Problem Statement: Technical Life Care needed a method to calibrate Hand-Held Dynamometers to a higher level of precision as these devices determine the muscle strength of someone in intensive care. Knowing the proper measurement allows doctors to quickly diagnose ICU survivors' physical function and determine the proper treatment. A wrong measurement could potentially lead to a misdiagnosis.
Morehouse was contacted to develop a fixture for their Hand-Held Dynamometers to add to the Portable Calibrating Machine (PCM). Their previous technique was insufficient and unsafe. This technique required two people to hold a pipe or rod. They would then place a hand-held dynamometer on it and begin to stack weights. Stacking weights can create serious issues. If weights are stacked, they may fall on a technician and cause injury or they may fall and need to be aligned and calibrated once more.
The Portable Calibrating Machine (PCM) saves the company time by only requiring one technician and is a safer method compared to the alternative method of stacking weights. The Portable Calibrating Machine (PCM) is a force calibration machine designed to measure smaller instruments under 2000 lbf capacity and is paired with a reference load cell and Morehouse indicators.
Hand-Held Dynamometer Adapter
Our PCM adapter allows load cells to measure and apply force to the Hand-Held Dynamometers, and the Morehouse indicator receives the readings. Currently, no company has any fixture to add Technical Life Care’s hand-held dynamometers to a Portable Calibrating Machine (PCM). The Morehouse team has created and found materials to fit within the parameters of the machine and lock the instruments into place.
Pinch Gauge Dynamometer Adapter
Morehouse as also developed an adapter that will fit mechanical pinch gauges. Pinch gauges can be calibrated from .25lb all the way up to 60lbs. Since these devices need to be calibrated with such accuracy, the PCM is the perfect machine to use with this new adapter. When using our reference load cell and Morehouse indicators with this adapter, we can guarantee a force application as low as 0.005 lbf based on the resolution of the reference standard used.
The company chose Morehouse because they have trust in the company. We are leading the industry with our knowledge and expertise to provide our customers with better solutions. We make sure our customers have the best quality adapters, calibration machines and carrying cases for their industry requirements.
The Navy had a big task for Morehouse. The Navy needed their Horizontal Test Bed calibrated. The Navy reached out to Morehouse to help come up with an accurate way to calibrate their Horizontal Test Bed. This machine produces 1.2 million pounds of force. The Morehouse team applied force measurement fundamentals to their problems and came up with appropriate fixturing through the creation of custom clevises. Clevises help to correctly makes use of tensile force to calibrate dynamometers, load links, tension rods, crane scales, and other weighing devices. These clevis sets were created by using the individual parts of the testing bed and breaking down the process into stages.
The custom clevis set was engineered to correctly adapt the load cells to the pulling pins of the Horizontal Test Bed. The attachment ensures that when the machine applies tensile forces, the force will be measured correctly.
Using only photographs and measurements provided by the Navy, the Morehouse team engineered a custom solution to adapt calibration load cells to the Navy's Horizontal Test Bed. Creating the custom clevis set was difficult because the only available information given was images and measurements, but the Morehouse team worked through it to create a solution. The Navy chose Morehouse due to decades of conducting business with Morehouse.
Morehouse sells it's custom clevis assembly for tension adapters which are used to calibrate weighing devices. The assemblies can be used with Morehouse Quick change Tension Members to minimize the error by improving tension alignment.
We helped the NASA international space station find a non load cell solution in a nickel coated proving ring to help Astronauts set the appropriate exercise forces. Throughout the world in industry and standards laboratories, the Morehouse Proving Ring is recognized for it's lasting reputation of unquestionable accuracy in the measurement of mechanical forces.
The Morehouse Proving Ring is an invaluable tool for the measurement of forces in industrial strength testing. We provided a custom solution to NASA stating a nickel coated proving ring capable of handling up to 5000 lbs of force, which is perfect for any environment, even outer space.
NASA partnered with us to create the ultimate exercise machine. Its purpose sends a clear message: keep or astronauts in peak physical condition even while on missions.
Our proving ring is the most accurate and durable proving ring in the world. With decades of experience and calibration we are able to help your testing machine, torque measuring dynamometer, thrust standard, electronic and hydraulic load cells, and much other force measuring devices and systems.
