The Honeywell OELD Optima Excel Local Display is a smart junction box for the Searchpoint Optima Plus and Searchline Excel infrared detectors for flammable hydrocarbons. The OELD includes an LCD screen for gas information, a "traffic light" indicator for at-a-glance detector status, and Bluetooth connectivity for simplified, non-intrusive maintenance. Simply pair the OELD with our intrinsically safe, ruggedized smartphone; then use the OELD smartphone app to interact with the gas detector from up to 10 meters (30 feet) away. For maximum flexibility, the gas detector can be mounted either directly or remotely to OELD to suit any situation.

Application Notes

Here's how some of our customers used this product.

Ethanol Detection in a Distillery

The Background: Our customer is a small distillery that seeks a reliable and cost-effective means of detecting ethanol leaks.

The Problem: Ethanol is highly flammable making leaks potentially dangerous.

The Solution: We recommended the Honeywell OELD Optima Excel Local Display with a Honeywell Searchpoint Optima Plus ethylene sensor. This combo gives local indication of Ethanol level as well as a color changing display indicating an alarm condition. The customer may further automate the gas detection as they expand and this transmitter also includes a 4-20 mA output they can run to a centralized panel in the future.
