Kistler Instrument Corporation, a worldwide supplier of precision sensors, systems and instrumentation for the dynamic measurement of pressure, force, torque and acceleration, announces the Type 4021A, a melt pressure measuring chain with ½ in.-20 UNF thread, designed to simultaneously measure short duration pressure peaks and temperatures.

• Design of Kistler Type 4021A incorporates a melt pressure sensor, constructed of a stable, high-temperature piezoresistive silicon sensing element, with an abrasion-resistant stainless steel diaphragm, and an integral amplifier, which is designed to match the sensor
• Sensor is offered in multiple lengths and angular configurations
• Pressure measurement ranges of 0 to 29,000 psi (0 to 3,000 bar)
• Temperature ranges of 32 to 662 F (0 to 350 C)
• Choice of cable lengths
• Allow for mounting of the sensor directly in the flow of material, eliminates time lag, enables direct real-time measurement of the process parameters determining product quality
• Ideal for use in demanding short-cycle process monitoring environments, such as those typically found within metal injection molding (MIM), ceramic injection molding or hot-runner systems
• Units may also be used for static pressure measurements within polymer pumps or other demanding environments
• Optional service kit for forming and cleaning the sensor hole (Type 4193) is recommended for use with this sensor
