OMEGA's new HHVB82 monitors your machinery to determine maintenance needs. All industrial machinery vibrates. Monitoring the level of vibration is a useful guide to a machine's condition. Poor balance, worn bearings, misalignments and loose fittings in the structure will increase levels of vibration. The HHVB82 measures acceleration of up to 200 m/sec and velocity up to 200 mm/sec. OMEGA's new vibration meter features auto shut-off function, built-in tilt stand, reading hold standard, stores minimum and maximum readings with push-button recall. A Vibration sensor with magnetic mount included.* RMS or Peak Vibration Readings (Peak value = 1.414 RMS value) * Acceleration Range: Up to 200 m/sec2 * Velocity Range: Up to 200 mm/sec * Frequency Range: 10 Hz to 1 kHz; sensitivity meets ISO 2954 * Functions: Auto off (after approx 20 min), reading hold, record minimum and maximum * Accuracy: ±5% +2 digits reading, 160 Hz, 80 Hz @ 23 ±5ºC * Calibration Point: Velocity 50 mm/sec (160 Hz), acceleration 50 m/sec2 (160 Hz) * Operating Temperature: 0 to 50ºC (32 to 122ºF) * Operating Humidity: <80% RH (non-condensing) * Power: 9 V alkaline battery (included) * Sampling Time: Approximately 1 sec * Meter Dimensions: 185 H x 78 W x 38 mm D (7.3 x 3.1 x 1.5") * Sensor Dimensions: 16 D x 29 mm H (0.6 x 1.4") * Meter Weight: 274 g (0.6 lb) * Sensor Weight: 38 g (0.08 lb)
