HOW THE LEAK ALARM WORKS

We use conductivity pins to detect liquid because nothing matches the precision of conductivity pins to detect a thin film of liquid at the bottom of a containment pan. This matters because detecting early can give a warning much earlier than other methods of detection. In addition, we use gold-plated pins that can’t corrode which provides maximum reliability. Since these pins can sit in place for a decade or more, it gives peace-of-mind to know that the gold surface is non-corroding. 

Furthermore, the conductivity sensing technology allows the unit to be powered from a battery.  Since the circuit operates at close to zero drain, it allows a battery to stay in place for a decade or more. This provides the reliability advantages and convenience of  battery power.  When the battery eventually runs, low, an alarm is given. 

In addition to these advantages, the conductivity sensors require no calibration. (unlike some capacitance sensors for example) 

INSTALLATION

To install the device, the conductivity leak alarm just needs to be placed into the space where the leaks need to be detected.  Super flexible cable makes it easy to deploy either of the leak alarms.  Once the battery is connected its ready to protect against leaks!

NO MAINTAINANCE

There is is nothing to wear out and no moving parts to limit the lifetime of a conductivity sensor. The gold plated sensing pins are immune to corrosion.

MODELS

T-LKP model has a tubular sensor only 23 mm [0.90″] diameter that fits inside ¾” NPT or ¾” NPS bungs. The pins sit a bit above the floor of the tank and so they will detect liquid level at around ½” of liquid. The electronics enclosure with ¾”NPT thread screws directly into a tank fitting. (or reducing bushing as needed)

AB1-LK  includes a flat disc that orients itself in the right position when descended.  The sensing pins are kept off the bottom by a couple of mm so as to eliminate false alerts that may be caused by condensation.
