Kistler has introduced the Type 4021B industrial melt pressure measuring chain. The chain is designed for the simultaneous recording of short duration pressure peaks to 3000 bar (29000 psi) and of temperatures to +350 °C (+662 °F), in support of a variety of plastics injection molding requirements.
The design of the new Kistler Type 4021B builds upon its predecessor model, the Type 4021A, incorporating a melt pressure sensor with stainless steel diaphragm and integral amplifier. The integral amplifier is designed to match the sensor to assist measurement accuracy. Type 4021B is offered in multiple shank lengths and angular configurations, as well as pressure ranges, with choice of integral or removable cable in varying lengths.
The Kistler Type 4021B allows for the sensor to be mounted directly in the flow of material. This is intended to eliminate the time lag typically associated with indirect measurement systems and enables real-time measurement of the process parameters that directly determine product quality. Type 4021B is designed for use in short-cycle process monitoring environments, such as those typically found within injection molding nozzle sensing or hot-runner sensing systems.
As the sensors are free of mercury or other transmission media, they are intended for use within medical, pharmaceutical and food-grade molding applications, as well as for polymer pump static pressure measurements.
