Cảm biến đo độ rung CE687 piezoelectric accelerometer 444-687-000-011 Meggitt Vibro Meter
Current output: 4 to 20 mA proportional to 0 to 1, 2, 5, 10 or 20 g, −25 to 90 °C, up to 1000 Hz.
The CE687 piezoelectric accelerometer is a general-purpose industry standard 4 to 20 mA loop-powered vibration sensor (vibration transmitter) with a piezoelectric sensing element, integrated electronics and a current output. It is available with a sensitivity of 4 to 20 mA proportional to either 0 to 1, 2, 5, 10 or 20 g, and in standard versions or Ex versions.
The CE687 is designed and manufactured for use in harsh industrial environments, including hazardous areas (potentially explosive atmospheres).
