Periodic Maintenance Items
Sensor Cleaning: Clean electrode and liner surface deposits (such as coal slurry water/viscous medium residue) quarterly using a soft brush and neutral cleaner; hard objects are prohibited to prevent scratching and damage.
Explosion-Proof Structure Inspection: Check the smoothness of flameproof joint surfaces monthly (gap standard ≤0.15mm), promptly replace aging sealing rings to ensure IP68 protection rating.
Electrical Performance Maintenance: Regularly calibrate the 4~20mA output signal (allowable error ±0.5%), test grounding resistance ≤4Ω to prevent electromagnetic interference.
Wear Parts Replacement: Monitor the condition of components such as O-rings; replace immediately if aging or wear is found to avoid leakage risks.

Key Maintenance
Prohibit Live Operation: Power must be cut off before maintenance; open the cover only after the device cools to room temperature, otherwise risks may occur.
Avoid Corrosive Solvents: Cleaners must be strictly neutral pH; strong acids or alkalis can corrode the liner or electrodes.
Prohibit Unauthorized Modifications: The explosion-proof structure (such as flameproof chamber or intrinsic safety circuit) must not be altered arbitrarily, otherwise safety certification becomes invalid.
