    The used formula: output value in Unit = (input value in mV - Offset) / Sensitivity. Tacho The speed is measured from tacho channel. The signal contains one or more pulses per one rotation. The pulses can also trigger the measurement. For further technical and contact information visit www.adash.eu, email: info@adash.cz...

  • Page 22: Settling Prolongation

    The correct reference value has to be set for speed measurement. E.g. when the standard tacho level is 0.5V and the pulses rich the 1.5V, then the value 1V should be correct. The negative pulses are not allowed, you need to use Adash converter for them. Pulses per rotation This value has to be set for correct speed evaluation, when more pulses are generated during one rotation.

    The standards should be rather determined for a narrow range of machines. The instrument uses the Adash limit values. These limits are not rewritten from any existing standard. It’s a result of 20 years of Adash engineering team experiences. It’s difficult to invent critical value definition which would be simple (that means not many parameters such as speed, power, bearing type, machine type and so on) and reliable.

    2 The sensor is mounted next to lubrication point on a bearing housing (measurement pad recommended). This option enables a perfect measurement. The disadvantage is a longer preparation, since the lubrication head and sensor must be mounted separately. For further technical and contact information visit www.adash.eu, email: info@adash.cz...

    2. Select the Lubri Mode and the input channel, which will be used for measurement. Push the START button. Then the instrument will automatically measure an actual lubrication state. In the beginning the instrument takes the initial g RMS value in the frequency band 500 - 25600 Hz. For further technical and contact information visit www.adash.eu, email: info@adash.cz...

  • Page 115: Ultrasound

    Higher frequency energy above 20kHz is best detected with an ultrasonic sensor. Most useful information is found between 30 and 50kHz. The Adash ultrasonic module enables monitoring ultrasonic energy. Ultrasound utilizes a solid, liquid or gas to transmit (will not exist in a vacuum), and is a very directional and short waveform.

  • Page 116: Measurement

    The ultrasound is demodulated to the frequencies around 1kHz and you can hear it in headphones. Use the volume buttons to set the correct level. Important note ! The signal in headphones is delayed 1 sec. It is because of digital processing, which takes this time. For further technical and contact information visit www.adash.eu, email: info@adash.cz...
