Keller High temperature pressure transmitters, for temperatures up to 150 degrees C, Series . Flush diaphragm, pressure ranges -1 Bar to 30 bar , with 4-20mA or 0-10v output.
Piezoresistive Pressure Transmitter for Applications in Bio-Reactors or Autoclaves
Digitally compensated / Rangeable / Digital and Analog Output
Piezoresistive pressure transmitter for applications in bio-reactors or autoclaves. The transmitter is compensated up to 150 °C and may be operated continuously or sterilised at this level, including the special circuit electronics.
The transmitters are supplied in absolute or gauge versions, with current or voltage output.
The sensing component is a micro-machined silicon pressure chip of high sensitivity. An independent temperature sensor is integrated on the surface of the silicon chip
