Kistler said that the 3 mm diameter 4004A pressure sensor for hot runner and additive manufacturing applications will provide three measurement ranges in 2022. #monitoring
According to the company, on Fakuma (October 12-16; Friedrichshafen, Germany), Kistler Group launched 4004A miniature pressure sensors for hot runners and 3D printing, which aroused the interest of processors and mechanical OEMs . These 3 mm diameter sensors will be available in mid-2022 and can be used in three measurement ranges: 500, 1000 and 1500 bar (approximately 7200, 14,500 and 36,000 PSI). The working and measuring range of this sensor is up to 350 C.
A Kistler spokesperson stated that the 4004A is a piezoresistive pressure sensor that can be directly deployed on the hot runner nozzle to ensure accurate characterization of the molding process. The sensor includes a transducer electronic data sheet (TEDS) and can be connected with up to three additional sensors via an adapter to create a measurement unit.
In addition to the new 4004A pressure sensor, Kistler is also equipped with three temperature sensors that can match different mold geometries with its product portfolio to ensure the quality of injection molding. Thermocouples 6196A, 6197A, and 6198A have a measurement range of 0 to 400 C (32 to 752 F).
Regarding the application of sensors to 3D printing, the spokesperson said that machine manufacturers are very interested in monitoring or controlling the printing status in the discharge nozzle.
The 6198A thermocouple with bayonet cap is one of Kistler's three new mold temperature sensors, which are used to monitor temperature regulation, flow and cooling in injection molding.
