Monitoring interstitial space in double wall tanks

Featured Product from Arjay Engineering Ltd.


2852-ILA Interstital Tank Leak Alarm

Part Number Starting: 2852-ILA
Reliable monitoring of the interstitial space in double wall tanks
Leaks from above or underground storage tanks can be costly, dangerous to worker health, and environmentally unsafe. Arjay provides sensors to monitor for leaks and spills. Probe variations can extend these applications to meet your specific needs.

For double walled tanks, above or underground, the Interstitial Leak Alarm is designed to alarm on a dry vs. wet condition within the walls. This unit will alarm from a leak within the internal tank or from an outside leak into the wall cavity.

The 2852-ILA probe monitors the interstitial space near the bottom of the tank and locks in on the capacitance field around the probe tip.
Any liquid that intrudes into this space will increase the capacitive field and initiate an alarm.

The leak source can be from the stored product leaking from the tank or from groundwater leaking through the outer wall.

Features and Benefits

  • Adjustable time delay and sensitivity to eliminate nuisance alarms
  • Remote electronics via standard twisted pair
  • Available with Intrinsic Safety Barrier for Hazardous Locations
  • SS and PVC wetted parts allow for corrosive environments
  • Capacitance technology responds to all types of liquids
  • Capacitance technology alarms on any liquid
  • No moving parts
  • Remote alarm unit mounts safely away from tank site

Leak Detection Alarms
Be alerted of any leaks that occur with reliable leak detectors from Arjay Engineering. The purpose of these area leak detection alarms is to detect and monitor the accumulation of liquid leaks in containments, floor spaces, and double wall tanks that are normally dry areas. When a liquid intrudes into this space, an alarm will sound to warn you that a leak is present. With over 40 years of capacitance experience, we've designed and manufactured all of our leak detection instruments with advanced technology that's unparalleled. With no moving parts and rapid response to all types of liquids, leak detection alarms from Arjay Engineering also available with Div. 1, Zone 0,1,2 ATEX and CSA/UL certification.
