Proven technology, proven designs –
quality products you can trust.


The Analog Transmitters GRP 100 / 200 are piezoresistive vacuum gauges perfectly suited for pressure measurements between 1400 and 1 mbar. Thanks to their durable aluminium oxide ceramic sensor, they are nearly insensitive to contamination and are therefore ideal for challenging applications.

  • Gas type independent measurement
  • Flexible analog output signals (4 – 20 mA or 0 – 10 V)
  • Long term stability and short response time
  • Chemically resistant ceramic sensor
  • Resistant against shock venting and vibration
  • Temperature compensated
  • Robust stainless steel housing
  • Zero adjustement by digital push button
  • Ultra low leakage rate < 5 ∙ 10-10 mbar ∙ l/s
