Portable Automatic Shutdown Double Probe Hand-Held Vibration Meter HG-908
Features: Small size, transducer included, True RMS measurement. Measuring parameters: vibration velocity, displacement,acceleration and high-frequency acceleration Battery powered, Accelerometer may be integrated or external cable connected. One button control both power and measurement.Very easy to use. 3 1/2 LCD digital display, sampling per second. Holding function. Automatic power off. Suitable for monitoring machinery vibration caused by imbalance,misalignment, gear & bearing faults and etc. Specifications: Testing ranges: Displacement 1—1999 m m (or 200 mil) Eq. peak-peak Velocity 0.1—199.9 mm/s (or 20 in/s) true RMS Acceleration 0.1—199.9 m/s2 (or 20 g) Eq. Peak High Frequency Acceleration: 0.1—199.9 m/s2 (or 20 g) Eq. Peak Overall accuracy: ±5% Temperature range: 0 - 50°C Frequency response: Displacement 10-1000Hz Velocity 10-1000Hz Acceleration 10-1000Hz (908B) 105000Hz (908) High Frequency Acceleration: 1000-5000Hz 10%
Configuration:
HG908: Separate accelerometer with magnetic mount & probe, long needle probe Battery: 9V 6F22/Rechargeable, 25/10 hours of continuous operation. Pickup: Accelerometer with handheld probe and/or magnetic mount Dimensions: 13×6×2.3 cm; Weight: 200 g Optional Intrinsically safe version with internal accelerometer
1.Preparation
1). Check the voltage of the battery: Press M<easure> key, observe the display on the screen. If there is an arrow on the top left corner, you need to replace the battery with a new one. 2). Set-up probe HG908 with outside accelerometer has 1 probe and 1 magnetic mount. When changing, take hold of the accelerometer to avoid rotation and damage of the cable.
2.Measurement
1). Select the measure parameters: HG908 has 4 vibration parameters. They are: a) Displacement(unit: mm=1/1000 mm): Equivalent peak-peak value b) Velocity (unit: mm/s) : True RMS Value; c) Acceleration (unit: m/s2): Equivalent peak d) High Frequency Acceleration (unit: m/s2): Equivalent peak 2). Functions of the M<easure> key: a).Key press: Power on and begin measuring; b).Key release: Hold the last measured value for twenty seconds and then power off automatically. 3). Stick the probe to the measured object (the pressure should be about 0.5-1 kg.)
3. Notes 1). Avoid intense impact, high temperature and immersed in water. 2). Keep the sensor plug clean and dry, and use it carefully. 3). Install the battery: a) Open the small back cover of battery cabinet (2 screws at the
end far away from the sensor at backside, see figure); B) Place a battery (6F22, 9V) correctly according to the polarity; C) Close the back cover and screw the tightly; D) If it has been put aside long-term, please take out the battery To avoid the battery liquid; 4) If the sensor has been used for over one year, please re-calibrate the sensor and the meter together to ensure the
precision.
4. Specifications 1). Measurement condition: Temperature: 0oC -45oC, Humidity< 85%, Non-causticity environment, without strong electric-magnetic field & strong impact. It can
be used in industry location by controlling the EMC environment throughout installation and/or usage. 2). Amplitude Ranges: Below 1 1999 m peak - peak (*) True RMS Velocity 0.1 199.9 mm/s Acceleration and High Frequency Acceleration: 0.1 199.9 m/s2 peak (*) *Note: peak-peak and peak are equivalent value means:
peak-peak=2.828*RMS while peak=1.414*RMS 3). Accuracy: 5% of display digit 2 Noise Level (without input): ACC< 0.3 m/s2, VEL< 0.5 mm/s, Disp< 3 m Frequency response accuracy: 5%; ( 10% for ACC 4.5 kHz - 10 kHz) Non - linearity: 5% 4). Sensor type: Shear type Piezoelectric Accelerometer 5). Frequency Response: 101000Hz (Inside Accelerometer) 105000Hz (Outside Accelerometer, Page on Model) High Frequency Acceleration: 1000-5000Hz 10% 6). Battery: 9V 6F22, 25 hours of continuous operation. 7). The Configuration: Standard: Outside accelerometer with magnetic mount and probe Optional: Inside Accelerometer with 2 handheld probes 8). Dimensions: 13 6 2.3 cm; Weight: 250 g.
