In industrial equipment vibration monitoring and fault warning scenarios, the installation quality of acceleration sensors directly determines the accuracy of measurement data - even for the same high-performance sensor, selecting the right installation method can achieve 100% performance, while selecting the wrong one may lead to data distortion, equipment misjudgment, and even sensor damage.

Today, we will systematically review the four most commonly used installation methods for industrial acceleration sensors, analyze the advantages, disadvantages, and applicable scenarios of each method, help you avoid selection and installation errors, and accurately match on-site needs.

1、Adhesive installation (most commonly used, preferred for cost-effectiveness)

Adhesive installation is the most widely used installation method in industrial scenarios. The core is to fix the sensor on the surface of the tested equipment with special adhesives (such as instant dry adhesive, epoxy adhesive) without any modification to the equipment.

✅ Advantage

Easy to install, no need for drilling or welding, no damage to the equipment body, suitable for various precision equipment such as machine tools, motors, and reducers.

Strong adaptability, whether it is flat, curved, small equipment, or narrow spaces, it can be flexibly installed.

Extremely low cost, cheap adhesive consumables, short installation time, and can be quickly deployed in bulk.

The measurement stability is good, and after being firmly bonded, it can effectively transmit equipment vibration signals without additional signal interference.

❌ Shortcoming

The environmental adaptability is limited. In high temperature (usually exceeding 80 ℃), high humidity, and oil pollution scenarios, the adhesive is prone to aging and detachment, leading to sensor loosening.

Disassembly is difficult as it may damage the sensor housing or leave adhesive residue on the surface of the device, affecting its appearance and subsequent installation.

High requirements are placed on the installation surface, and it is necessary to clean the oil stains, dust, and rust on the equipment surface in advance, otherwise it will significantly reduce the bonding strength and affect the measurement accuracy.

Applicable scenarios

Industrial scenes at room temperature, dry, and free of oil stains, such as vibration monitoring of ordinary motors, water pumps, fans, and machine tools, are particularly suitable for precision equipment that does not allow damage to the equipment.

2、Bolt installation (most stable, preferred for high precision)

Bolt installation is the preferred installation method for high-precision monitoring scenarios and the mainstream choice for long-term monitoring of industrial equipment, which uses screws (such as hexagonal bolts and countersunk bolts) to fix sensors on the preset installation holes of the equipment.

✅ Advantage

The fixation is the strongest, the connection stiffness is high, it can transmit equipment vibration signals to the maximum extent, the measurement accuracy is the highest, and there is no signal attenuation.

Strong environmental adaptability, resistant to harsh industrial environments such as high temperature, high humidity, oil pollution, dust, etc., not easy to loosen or fall off, with a long service life.

Easy to disassemble, reusable, suitable for scenarios that require regular calibration and replacement of sensors.

Uniform force distribution can avoid additional vibration caused by loose installation of sensors and reduce measurement errors.

❌ Shortcoming

Drilling and tapping of equipment are required, which may damage the equipment body and is not suitable for precision and vulnerable equipment (such as precision instruments and thin-walled equipment).

The installation process takes a long time and requires professional tools (drill bits, wrenches), resulting in low efficiency for batch deployment.

The cost is relatively high, requiring additional processing of installation holes, and the cost of bolt consumables and labor is higher than that of adhesive type.

The installation location is limited, and there needs to be sufficient space and thickness on the surface of the equipment in order to drill and fix it.

Applicable scenarios

High precision vibration monitoring and long-term monitoring scenarios, such as steam turbines, compressors, large fans, metallurgical equipment, etc., are particularly suitable for equipment monitoring in high temperature and harsh environments.

3、Magnetic installation (most flexible, preferred for temporary monitoring)

Magnetic installation is the best choice for temporary monitoring and inspection scenarios, as it utilizes the strong magnet that comes with the sensor to directly adhere to the surface of the equipment (only applicable to ferromagnetic materials) without the need for bonding or drilling.

✅ Advantage

Installation and disassembly are extremely convenient, without the need for any tools, and can be completed within seconds, suitable for temporary inspections and equipment debugging.

Without damaging the device itself, it can be reused, and the installation position can be flexibly changed to meet the temporary monitoring needs of multiple devices.

No need to clean the surface of the equipment, even with slight oil stains and dust, it can stably adsorb (under the premise of sufficient adsorption force).

Moderate cost, one-time investment, can be reused for a long time, suitable for batch inspection scenarios.

❌ Shortcoming

Only applicable to ferromagnetic material equipment (such as carbon steel, cast iron), non ferromagnetic materials (such as stainless steel, aluminum alloy) cannot adsorb.

Due to limited fixed strength, high vibration and high-speed rotating equipment (such as high-speed motors and rotors) are prone to looseness and detachment, posing safety hazards.

The measurement accuracy is slightly lower than that of bolt type and adhesive type, and the gap between the magnet and the equipment surface can cause signal attenuation, affecting data accuracy.

The environmental adaptability is average. In high temperature scenarios (over 100 ℃), the magnetic properties of the magnet will weaken and the adsorption force will decrease.

Applicable scenarios

Temporary monitoring, equipment inspection, and troubleshooting scenarios, such as regular equipment inspections, temporary debugging, multi device rotation monitoring, and equipment surfaces made of ferromagnetic materials.

4、Welded installation (most durable, preferred for harsh environments)

Welding installation is the process of directly welding the sensor base onto the surface of the equipment, achieving permanent fixation through welding. It is an exclusive installation method for extremely harsh environments (high temperature, high pressure, strong vibration).

✅ Advantage

The most secure fixation, integrated with the equipment after welding, with no risk of looseness or detachment, able to withstand extreme environments such as strong vibration, high temperature, and high pressure.

The measurement accuracy is extremely high, with no installation gaps and no attenuation in vibration signal transmission, making it suitable for high-precision monitoring in extreme environments.

The longest service life, the welding joints are not easily aged or damaged, and can adapt to long-term and continuous industrial monitoring needs.

❌ Shortcoming

The welding process can cause significant damage to the equipment, altering its surface structure and potentially affecting its strength, making it unsuitable for precision and vulnerable equipment.

The installation is difficult and requires professional welding personnel and tools. It takes a long time to install and has high costs.

Unable to disassemble, once welding is completed, the sensor cannot be replaced or calibrated, resulting in extremely high maintenance costs in the later stages.

The welding quality affects the installation effect, and weak welding can cause signal distortion and even sensor detachment.

Applicable scenarios

Extreme harsh environments, permanent monitoring scenarios such as metallurgical furnaces, high-pressure equipment, mining machinery, ship equipment, etc., and equipment that allows welding without the need for later disassembly of sensors.

Final reminder

When choosing the installation method of an acceleration sensor, there are three key points to consider:

Equipment operating conditions (temperature, vibration, environment)

Measurement accuracy requirements

Is it allowed to damage the equipment.

Prioritize adhesive (cost-effective) and bolt on (high-precision) for daily scenarios; Select magnetic suction for temporary inspection; Choose welding for extreme environments. Attention should be paid during installation: the installation direction of the sensor should be consistent with the vibration direction of the equipment, and the installation surface should be clean and free of gaps to avoid measurement errors caused by improper installation.
