LU and LPD Leak-Detection & Overfill-Alarm Systems

Brand: OMNTEC Mfg, Inc
OMNTEC’s LU and LPD leak-detection and overfill-alarm systems provide continuous, accurate monitoring in a variety of applications. Typical applications are reservoirs, sumps, dry interstitial spaces and dispenser pans.  

These easy-to-install controllers alarm for in tank levels and leak conditions. The LU controllers are capable of accepting up to 9  sensors for high level and leak detection. 

The LPD controllers are capable of accepting up to 9 sensors for in tank levels and product distinguishing leak detection.  

The electro-optic sensors used with these controllers allow users to easily cycle all sensors through a simulated leak, with the press of a single button.  

This feature eliminates the need to remove the sensor from its location.

An alarm condition is visually signaled by a dedicated LED indicator, which remains lit until the alarm condition is corrected.  

Alarm conditions are audibly annunciated via a 95-decibel piezoelectric pulsing horn.  RA-series remote annunciators add high-level remote audio-visual alarms without the need for external AC power.

The LU-SP series controllers accommodate a variety of special applications.

The NEMA 4X rating of the LU and LPD series controllers indicates a weatherproof, corrosion-resistant product.  

These controllers are ruggedly constructed to provide reliable and cost-effective performance.
