Current output: 4 to 20 mA proportional to 0 to 10, 20, 25, 50 or 100 mm/s, ?25 to 90 °C, up to 1000 Hz.Voltage output: 100 or 50 mV/g, ?25 to 90 °C, up to 10000 Hz.The PV686 is a general-purpose piezoelectric vibration sensor with a piezoelectric sensing element and integrated electronics that combines two industry standard sensors in a single casing, namely: (1) a 4 to 20 mA loop-powered vibration sensor (vibration transmitter) with a sensitivity of 4 to 20 mA proportional to either 0 to 10, 20, 25, 50 or 100 mm/s and (2) an IEPE (integrated electronics piezo electric) vibration sensor with a sensitivity of either 100 or 50 mV/g. It is available in standard versions or Ex versions.The PV686 is designed and manufactured for use in harsh industrial environments, including hazardous areas (potentially explosive atmospheres).FeaturesDesigned for general-purpose vibration measurement, typically balance of plant (BOP) machinery such as compressors, gearboxes, motors, pumps and fansCombined industry standard 4 to 20 mA loop-powered vibration sensor (vibration transmitter) and IEPE (integrated electronics piezo electric) vibration sensor in a single casingQuasi-static output signal (4 to 20 mA proportional to 0 to 10, 20, 25, 50 or 100 mm/s) indicating ‘overall’ vibration and dynamic voltage output signal (100 or 50 mV/g) suitable for spectral analysisSupports protection/monitoring and control applications with a single deviceIP67 protection rating
