Application

Vibrating condition monitoring on motors, pumps, gearboxes, compressors, generators, rotating machinery and vibrating structures. Detection of low frequency structural oscillations or excessive vibration at shaft rotational frequencies and high frequencies, as generated by deteriorating bearings and by resonant structures.

The sensor can also be used in the opposite mode, where it detects the absence of vibration on a machine that should normally be vibrating, thus indicating the failure of a drive motor, a severed coupling or a power failure. Vibrating screens and material conveyancing ducts or processing machines are typical examples.

It is possible to combine both modes of monitoring simultaneously by using the Trolex TX9042/4 Programmable Vibration Sensor Controller with frequency input conditioning modules.
A range of instrumentation and monitoring modules is available from Trolex to which vibration sensors can be directly connected to provide a flexible choice of display and control functions.

Installation

Safety Precautions
Hazardous areas
Do not disassemble the sensor whilst in a hazardous area or use a sensor that has a damaged housing in the hazardous area.
Protect the Vibration Sensor from excessive shock during handling and installation as this may cause permanent damage to the internal piezo crystal assembly.
If possible, mount the sensor in a position where it is protected from direct impact and blows.

Tools and Test Equipment Required
No special tools are needed.

Installation

Checkpoint
The best performance will be obtained from the Vibration Sensor by careful consideration of the mounting position.

1. Maximum output will be generated when the vibration is acting along the centre axis of the sensor. This is particularly important when monitoring bearings and ventilation fans.
2. The sensor is equally effective at detecting vibration in housings and casings. It is important to identify points of vibration where the maximum output signal can be obtained.
3. It is important to prepare an accurate mounting point for the Vibration Sensor and if possible, choose a relatively flat area where a spot face of about 25 mm can be created.
4. Apply a small amount of suitable thread lock to the mounting bush to ensure a good vibration coupling.
5. Tighten the Vibration Sensor to 8 Nm.
6. Movement of the cable itself can influence the output signal. Clip the cable as close as possible to the Vibration Sensor to restrain it.

Connections
In order to avoid electrical pickup through the case of the sensor from the machine being monitored, the machine should be properly earthed in compliance with local regulations.
It is recommended that the sensor cable is looped and then tied with a cable tie to the main body in order to avoid excessive wear.

Electrical Connections to Lead

Checkpoint
If a good earth is not possible, the sensor and the cable overbraid should be electrically isolated from the machine. The screen of the cable should be connected to earth at the monitoring equipment, it should not be earthed at the motor. The cable overbraid should be left unconnected.

Electrical Connections to 4 Pin M12 Type Connector

Checkpoint
The minimum cross sectional area of the wiring used between the circuit to the transition PCB is 0.085 mm2.
The electrical circuit in the hazardous area (black and white wire) must be capable of withstanding an ac test voltage of 500 V RMS to (inner cable screen or enclosure body and external screen) for 1 minute.

Maintenance

Introduction
To keep your Vibration Sensor in the best possible condition and minimise downtime, Trolex strongly recommends that you carry out regular planned preventative maintenance and keep records of the maintenance carried out.
The planned preventative maintenance for the Vibration Sensor consists of a number of tasks to be carried out at regular intervals. These tasks are listed in the maintenance schedule below:

Vibration Sensor – Check

1. Check the exterior of the vibration sensor for cracks, penetration and any other signs of damage.
2. Check that the wiring is secure and free from damage.
3. Check that the vibration sensor is securely mounted.
4. If any part of the vibration sensor shows any signs of damage, deformation or missing parts, contact your local Trolex service agent or service@trolex.com for advice on repair or replacement.
5. After the completion of all maintenance, update the maintenance records.

Vibration Sensor – Calibrate

1. Under normal circumstances, the calibration of the vibration sensor will not change significantly.
2. Check the accuracy by comparing the display reading with a reference value of frequency.
OR
2. Alternatively the vibration sensor can be removed and returned to your local Trolex service agent, for checking and calibration across the full operating spectrum. Contact service@trolex.com for further information.
3. After the completion of all maintenance, update the maintenance records.

Disposal

Part of the ethos of Trolex is sustainable design. The vibration sensor contains materials that can be recovered, recycled and reused. At the end of its useful life ensure that the vibration sensor is recycled in accordance with local laws and bylaws for the geographic area where it is located. The end of its useful life is to be determined by the owner/operator of the equipment and not Trolex. Ensure that the vibration sensor is recycled by licenced waste contractors with the appropriate licences for handling metallic waste in the geographic area where the vibration sensor is located.

Checkpoint
Consult your local Trolex service agent or the Trolex Product Support Department if you require assistance with disposal: service@trolex.com

Maintenance Records

Implement a planned preventative maintenance process and keep good maintenance records.
Consult your local Trolex service agent or the Trolex Product Support Department: service@trolex.com for help in implementing a planned preventative maintenance process.
