  1. We also manufacture compound pressure sensors (gauge pressure of 500 kPa or less).
  2. Make sure that the operating vacuum pressure is 10 kPa abs or more. (Operating temperature range: 0-60°C)
  3. Use a wiring cable for atmospheric pressure correction.
  4. We also manufacture high-accuracy pressure sensors (accuracy: ± 0.25% F.S. or less).
