Sense L - Leakage sensor

More safety by continuous monitoring of the mechanical seal

With the Sense L, you reliably monitor leakage at your rotary joints and prevent uncontrolled media leakage. A decisive advantage especially with environmentally critical media – and effective protection of the bearing against escaping water or steam. You can detect critical leakage quantities in good time and intervene before the plant is damaged.

Ideal for:

  • Paper industry
  • Plastics manufacturing
  • Nonwoven
  • 24/7 continuous operation
  • Machine retrofit for Industry 4.0

Your advantages for highest reliability

leakage monitoring

They protect your plant from leaking media and prevent costly damage as well as maintenance-related downtime.

Problems with the mechanical seal
recognized quickly

The Sense L leakage sensor is an important component for predictive maintenance.

Combinable with
Sense W

Sense L and Sense W form a powerful duo to detect spontaneous mechanical seal failures and better plan maintenance.


The sensor technology for your rotary joints can be easily integrated into the control system using the IO-Link standard. The system is compatible regardless of the manufacturer.
