Multi-Alarm Digital Float Sensor

The SpillSens product is a digital float level sensor specifically designed to act as an early warning system for blockages and overflow risks in manholes.

As a robust and economical product, it uses innovative technology to detect different tilt angles and thus manage progressive levels of alert.

SpillSens is certified for use in potentially explosive areas.

It is compatible with various data logger models, including the IS Log product, for alarm transmission and supervision from a centralized platform.
