VeriGAP™ 504-1000 Series
Line Powered Ultrasonic Gap Switch
Wide Range of Applications
Performance is unaffected by changes in liquid
density, pressure, or electrical properties.

Major Breakthrough
The VeriGAP level switch is the only safe gap
switch available for high level alarming or
indication. All other gap switches are inherently
low level fail safe only. With most low-level
fail-safe devices, either an absence of material
or a component failure will indicate a low level
alarm. With most high level fail-safe devices, the
presence of material will only trigger an alarm if
the system is functioning properly. A component
failure, such as separation of the crystals, will
cause the device to indicate an absence of
material. This will result in a normal condition,
even if the tank is over filling.

Guaranteed Safety

Outperforms Generic Gap Switches

No opportunity for error in calibration or
adjustments in gain controls.

VeriGAP overcomes the problems inherent in
genric gap switches by testing the entire system
(crystals, crystal bonding,electronics and relay)
on demand, eliminating the possibility of a spill.
Unlike other gap switches with so-called
self-testing features, the VeriGAP requires no
calibration. This eliminates the potential for error
or spills during installation and setup.

Local Control

Ideal for Liquid Measurement

This line-powered version of the 504 Series gap
switch has its 5A DPDT relay where you need
it...built into the unit and close to pumps, valves,
horns and other final control elements.

The VeriGAP is ideal for high and low point level
measurements in liquids. It is not affected by
variations in viscosity, density, pressure,
temperature, or electrical properties.

Verify™ circuitry checks that the complete system
(crystals, crystal bonding, electronics and relay) is
functioning correctly.

No Calibration Required
