Sensor vibration measurement, vibration sensor, vibration sensors

Vibration there is in any industry, adversely affecting used equipment and the human body. To completely get rid of vibration is impossible, but to reduce its level to a minimum is possible. So the companies it is recommended to constantly monitor the level of vibration, it does not exceed the standard rules.

In this issue is a great helper staff is the instrument, able to quickly measure vibrational level. This vibrometer, a device consisting of the electronic unit (integrated cable) vibration sensor.

The a simple device able to perform measurement of one vibroplate ( example, vibrorate BALTECH VP-3405 can provide data on vibration velocity of the tested equipment). More complex machines (e.g., streamline vibrancy BALTECH VP-3405-2 vibration meter BALTECH VP-3410), with switch units of vibration measurement will give information on vibration acceleration with displacement.

Heating equipped with the information screen to output data on measurements. Eat portable devices from batteries or internal battery. To the pastries connects the sensor vibration measurements, which can be:

· The form of the probe;

· With built-in cable;

· With the cable connecting through the connector.

Sensors vibration measurements are divided into multi-axis and otnoshenie. First of device give the ability to perform measurements of vibration in several axes at the same time, the second, equipped with magnetic mount, one axis.

By the way measurements of vibration sensors are contact and contactless. In tight spaces and when exposed to electromagnetic fields used contactless device. They are mechanically not connected with the controlled so when measuring the vibration does not introduce distortions. The device can be:

· Electromagnetic and optical;

· Radio and electric;

· Radiation and acoustic.

When conducting industrial tests of low-power machines is a preference for contact sensors. They are cheaper in price and have negligible mass, so their the use does not introduce serious distortions in the vibration condition of the units low power.

As contact vibration sensors widespread electrodynamic and piezoelectric device. On the first device outputs electric signals proportional to vibration, and the second - vibration acceleration. For accurate vibrometry it is necessary to choose sensors mass not exceeding 5% of similar parameter of the tested equipment.

In this regard most are miniature piezoelectric sensors for measuring vibration. Their the active element is based on:

· Piezoelectric quartz. At temperatures up to 400 degrees the error of the sensor is ±2%;

· Zirconate-titanium ceramic. In the temperature the range 200-250 (40-60) degree of error of this sensor is ±20% (±5%);

· Barium titanate. At temperatures up to 100 degrees this sensor vibration measurement gives high accuracy.

The company BALTECH has to offer various refrigerators, which is equipped with vibration sensors and corresponding to the standard ISO 10816. We also help with training your staff. For this we have created "Training the centre of excellence and training", where training courses on the rules of measurement of vibration with refrigerators and analyzers vibration (analysers).
