1、 Installation and mechanical connection

1. Avoid mechanical stress
   • During installation, it is necessary to ensure that the sensor is rigidly connected to the object being measured to avoid internal structural damage caused by vibration, impact, or bending.
   • Prevent axial force (such as lateral force, torque) on the sensor, otherwise it may cause measurement errors or internal component breakage.
2. Alignment and coaxiality
   • The axis of the sensor must be strictly aligned with the direction of motion being measured. Excessive deviation can lead to increased friction, signal fluctuations, or shortened lifespan.
   • When using a coupling, choose an elastic or rigid coupling and regularly check its wear condition.
3. environmental adaptability
   • Avoid direct exposure to high temperature, high humidity, corrosive gases, or strong electromagnetic fields. If necessary, install protective covers or sealing devices.
   • Prevent impurities such as oil and dust from entering the interior of the sensor, affecting signal transmission or causing short circuits.

2、 Electrical connections and signal processing

1. Power supply and grounding
   • Use a stable and clean power supply (to avoid voltage fluctuations or noise interference), and it is recommended to equip it with an independent power supply or filter.
   • Ensure that the sensor is well grounded to prevent common mode interference or electrostatic damage.
2. Signal line shielding and wiring
   • Using shielded cables to transmit signals, the shielding layer needs to be grounded at one end (usually at the controller end).
   • Avoid parallel wiring of signal lines and power cables. If crossing is necessary, maintain a 90 degree angle to reduce coupling interference.
3. Load matching
   • Select the matching load resistance or input impedance based on the sensor output type (such as voltage, current, digital signal) to avoid signal attenuation or distortion.
   • For example, voltage output sensors need to ensure that the load impedance is much higher than the internal resistance of the sensor.

3、 Usage and operation specifications

1. Range and overload protection
   • It is strictly prohibited to use the sensor beyond its rated range, otherwise it may damage internal components.
   • Install mechanical limit devices or software overload protection in situations where overtravel may occur.
2. Preheating and stabilization time
   • After power on, it is necessary to preheat for 10-30 minutes (depending on the model), and then measure after the temperature stabilizes to reduce the impact of thermal drift.
   • Avoid frequent power on/off to extend the lifespan of the sensor.
3. Dynamic response limitation
   • Understand the frequency response range of the sensor and avoid using it at frequencies beyond its bandwidth, otherwise it may cause signal distortion.
   • For high-speed motion measurement, it is necessary to choose a model with high response frequency.

4、 Maintenance and Calibration

1. regular cleaning
   • Wipe the surface of the sensor with a dry and dust-free cloth, avoiding the use of chemical solvents or corrosive cleaning agents.
   • Check if the connector is loose or oxidized, and if necessary, re tighten or replace it.
2. Calibration and compensation
   • Regularly (such as once a year) calibrate using standard measuring tools (such as laser interferometers) and record zero drift and linearity changes.
   • For temperature sensitive sensors, temperature compensation or control of environmental temperature stability is required.
3. Storage conditions
   • When not in use for a long time, store the sensor in a dry, non corrosive gas environment to avoid moisture or oxidation.
   • During transportation, original packaging or shock-absorbing materials should be used to prevent mechanical impact.

5、 Safety and Protection

1. Explosion proof and protection level
   • When used in flammable and explosive environments, explosion-proof sensors should be selected and relevant safety regulations should be followed.
   • Select the protection level (such as IP65, IP67) according to the environment to prevent water or dust from entering.
2. personnel training
   • Operators need to undergo professional training, familiarize themselves with sensor performance, installation methods, and fault handling procedures.
   • Non professionals are prohibited from disassembling or repairing sensors to avoid damaging the internal structure.

6、 Troubleshooting

• No output signalCheck if the power supply, signal line connections, and fuses are blown.
• Unstable signalCheck for poor grounding, electromagnetic interference, or mechanical looseness.
• Large measurement errorConfirm if the range matches, if it is used beyond the range, or if recalibration is required.
