The Type 4021A from Kistler Instrument Corp., Amherst, NY, is a melt pressure measuring chain with 1/2 in.-20 UNF thread, designed to simultaneously measure short-duration pressure peaks and temperatures. The device incorporates a melt pressure sensor with a stable, high-temperature piezoresistive silicon sensing element, an abrasion-resistant SS diaphragm, and an integral amplifier designed to match the sensor. The sensor is offered in multiple lengths and angular configurations, in pressure measurement ranges of 0–29,000 psi and temperature ranges of 0°C–350°C, and with a choice of cable lengths. You can mount the sensor directly in the flow of material for direct real-time measurement of process parameters determining product quality. Applications include metal injection molding, ceramic injection molding, or hot-runner systems.
