Miniature Quartz Force Sensor Measures Pressure on Injection Molding Cavities and Other Short-Term Quasi-Static Processes

March 8, 2007, Depew, New York, USA – PCB Piezotronics (PCB®) has introduced Model 219A05 miniature charge output quartz force sensor, designed for industrial applications where space at a premium. The sensor is ideal for obtaining an indirect measurement of injection molding cavity pressure by positioning the sensor behind an ejector pin. The high stiffness property of the sensor allows them to follow very fast transient events. They may also be used to measure short term, quasi-static processes. The removable cable allows for a choice of lengths and terminating connector type, and facilitates easy field repair, in the event a cable is damaged.

Full scale measurement ranges up to 560 lb (2.5 kN), and compact size of 0.24 inch (6 mm) diameter x 0.24 inch (6 mm) height, allows the sensor to be used for other applications involving compression forces, such as push buttons, pin insertion on circuit boards, switches, and actuators.
