PCB Piezotronics has introduced Model 219A05, a miniature charge output quartz force sensor that is designed for industrial applications where space is at a premium. The sensor is suitable for obtaining an indirect measurement of injection moulding 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.
