Environmental Sensors

The Leakage Sensor for Double-Walled Tanks The VISY-Stick Interstitial is an interstices sensor and is used for the quick detection of leakage. It is used in double-walled tanks when the interstices have been filled with a leak-detection fluid. If the level of the liquid in the defined area of the interstice changes, an alarm is triggered.

Continuously measures liquid level and temperature

Immediately triggers an alarm in case of leaks

Simple and low-cost installation and start-up

The Sensors for the Monitoring of Manhole and Dispenser Shafts

The VISY-STICK Sump sensors are used to monitor the manhole shafts and the shaft below the dispenser. The sensors detect any liquids which may collect in the shafts and can quickly and precisely distinguish between water and fuels.

Measurement of water level in manhole or dispenser shaft

Alarm is triggered when fuel and water and detected

Encapsulated design for protection from contamination

Equipped with manipulation guard

The Leakage Sensor for Double-Walled Tanks VISY-Reed Interstitial sensors detect the presence of liquids in the interstices of double-walled tanks. They function as alarm systems and monitor the level of the liquid. VISY-Reed Interstitial is available as a "Dry" variant for dry interstices and a "Wet" variant for interstices filled with liquids.

Sturdy and stable design

Housing made of brass, floater made of stainless steel

Response threshold at about 30 mm

The Sensors for the Monitoring of Manhole and Dispenser Shafts

VISY-Reed Sump sensors detect liquids in the manhole shaft and under the dispenser. They function as alarm systems and monitor the level of the liquid. VISY-Reed sensors are a low-cost solution for simple and reliable detection of liquids.
