Lake Orion, MI - Sensor Developments' Model 90285 test stand, is another of a growing family of custom sensor based test systems developed to satisfy its customer's unique requirements. The stand's function is to measure the rotational drag (torque) in an automotive distributor and verify that this torque is below preset limits.

The stand, constructed on a rigid steel base table, uses adapter plates to accept a variety of distributor models. A unique, slide mounted motor, torque sensor and friction coupling mechanism mounted below the table's surface, automatically engages the distributor's drive shaft when installed.

The sensing element for the test stand is a SDI 01224 rotating torque sensor and the NEMA control console contains a variation of SDI's PMAC 2000 transducer signal conditioner.

The test itself lasts less than 10 seconds and the distributor "change-out" can be performed in less than one minute. One of the many pieces of information gathered from the test is the maximum torque achieved and the corresponding RPM.

The design of the system can be easily modified to test other types of rotating components. For more information on this, or other test stand applications, please contact the SDI engineering sales team at (248)-391-3000 or toll free at (888) SENSOR-1.
