Main Features

IFM E43378 Coaxial Pipe for Level Sensors – Accurate Oil Level Measurement with EMI Shielding

Engineered for demanding process environments, the IFM E43378 coaxial pipe enhances capacitive level sensor performance in low-dielectric media such as oils and oil-based fluids. By providing a stable reference around the probe, it enables precise level detection in tanks, sumps, and process vessels where conventional setups struggle—without imposing a minimum clearance to the vessel wall. Its design minimizes electromagnetic interference for dependable switching to pumps, actuators, and valve systems in automated process control.

Key Benefits

• Reliable detection in low-permittivity (low dielectric) media, including oils
• Effective suppression of electromagnetic noise for stable sensor outputs
• No minimum spacing to vessel wall—ideal for confined or narrow tanks
• Supports consistent level switching for pump and valve automation
• Straightforward integration with existing sensor mounting arrangements
