6165A

These piezoelectric cavity pressure sensors are suitable for low-viscosity crosslinking compounds.
Main features / advantages
  • Pressure range: 0 … 200 bar
  • Exchangeable cable
  • Resistant against penetrating resin due to welded diaphragm design
  • For industrial use during the embedding of chips and circuit boards (transfer molding)
  • High-sensitivity sensor housed in a sealed cartridge
The Type 6165A is a high sensitivity sensor with a 2.5 mm front diaphragm which is welded into a robust 4 mm diameter cartridge. This welded annular gap design prevents the ingress of low-viscosity resins and so ensures a high quality signal with no distortion. Cables are exchangeable to facilitate simple cable exchange and cable repair. The pressure acts directly on the front of the diaphragm and is in turn conveyed to the measuring element, which outputs an electric charge that is proportional to the pressure. This is converted by an amplifier to a voltage ranging from 0 … 10 V and is then available at the amplifier output. The sensor is available in two cable designs. The coaxial design uses high-insulation cables that do not need to be laid in the mold. The practical single-wire design is based on a cable that can be cut to any length. The connector with cut and grip technology can be connected upon installation in the mold. This facilitates simple installation and service.
