Inaccurate tank level readings, signal interference from nearby equipment, and cable degradation in harsh chemical environments — these are the top reasons liquid level monitoring systems fail in petroleum and chemical plants. The wrong cable means downtime, safety risks, and costly rework.The DQYVP 4 core 0.2mm² shielded liquid level cable is built specifically for sensor signal transmission and tank venting applications. It combines a tinned copper braid shield with an oil-resistant polyurethane jacket to deliver stable signal output in demanding tank gauging and ventilation setups.Core Parameters

Why This Cable Works in Tough Conditions
- Oil and chemical resistance. The PUR jacket withstands continuous exposure to diesel, crude oil, solvents, and mild acids — common in refinery tank farms and chemical storage where standard PVC cables crack within months.
- Reliable EMI shielding. Tinned copper braid blocks electromagnetic interference from VFD-driven pumps, radar level transmitters, and switchgear nearby. Signal drift stays under 1% even in electrically noisy tank areas.
- Multi-function in one run. Four cores let you run level sensor signals and vent solenoid control on a single cable, cutting penetration points through tank walls and reducing installation time.
- Flexible for tight tank interiors. Small 6.5mm diameter and soft PUR jacket make routing through ladder trays, cable glands, and narrow vent pipes straightforward — no pre-heating or special bending tools required.
