Abstract: An apparatus can be assembled between a pump and a motor driving the pump for a measuring torque and speed. The apparatus can include a housing having a motor attachment port and a pump attachment port. A primary coil is supported by the housing. A shaft has a first outer end and second outer end and an inner portion located within the housing. The first and second outer ends are connectible to a motor and a pump to suspend the shaft between the motor and the pump only by the outer ends of the shaft. A strain gauge transducer component is operably associated with the shaft. A secondary induction coil is mounted on the shaft and is located sheathed within the primary coil for providing power to the strain gauge transducer component. A wireless output of readings from the strain gauge transducer component is provided.

Abstract: A transducer for measuring the amount of lateral deflection taking place at the tip of a core-pin inside a mold or die cavity. Non-uniform cavity pressure and cooling patterns make core-pins prone to deflection resulting in out-of-tolerance thin and thick wall sections of the finished part. The transducer provides a means of determining deflection as it occurs during the molding process for statistical quality control. Real time measurement of the core deflection allows discrimination of unacceptable and reject parts for an automatic part sorting process. In the preferred embodiment a plurality of strain gauges mounted on the core-pin outside of the mold cavity provide real time electric signals of lateral deflection that can be used to automatically segregate reject parts and provide for statistical process control.

Abstract: A generally rectangular mold pressure sensor body contains an electro-mechanical sensing element designed to engage and be actuated by a mold ejector pin. The plastic body is generally rectangular in side view with appendages extending from either side of the body in plan view. The appendages engage pockets milled into channel sidewalls in the mold ejector plate. These appendages position the sensing element under the ejector pin, and retain the sensor body in the mold ejector plate. Extending from the forward end of the sensor body is a tongue of less thickness than the sensor body. The tongue may be removed to adjust the location of the sensing element relative to the end of the channel.
