Cavity pressure sensors for low-pressure RTM (±2bar to ±50bar, 0 to 250°C, front ø9 mm) / 4001A

These piezoresistive cavity pressure sensors for low pressure and temperature are suitable for composite applications, such as RTM and SMC.

4001A

These piezoresistive cavity pressure sensors for low pressure and temperature are suitable for composite applications, such as RTM and SMC.
Main features / advantages
  • High temperature, low pressure and viscocity measurements up to 275°C
  • Unlimited measuring time
  • Two separately configurable pressure ranges
  • Temperature-compensated pressure signals
  • Measures pressure and temperature with one sensor
Type 4001A is a robust, low-pressure measuring chain for high-temperature applications. The design is based on the piezoresistive measurement principle. Therefore, it includes a signal amplifier matched to its individual sensor. The measuring chain allows both pressure and temperature to be measured simultaneously at the same positon in the cavity. The pressure is transferred directly to the high temperature measuring element via a sealed diaphragm which forms part of mold wall.
