DL5PPB-300-0000-000 HONEYWELL

Description

The Honeywell DL5PPB-300-0000-000 is the rugged PVC warrior of the DL5000 Equilibrium Probe family, engineered to sniff out dissolved oxygen down to 0.1 ppb in the murkiest waters. Paired with a UDA2182 analyzer, this immersion-ready sentinel turns invisible gas molecules into rock-solid 4-20 mA decisions—keeping boilers happy and fish alive.

Application Scenarios

In a sprawling Ohio municipal wastewater plant battling 2 800 m³/day of raw influent, four DL5PPB-300-0000-000 probes dive 3 m deep into aeration basins. Old galvanic sensors fouled weekly, spiking energy bills €38 k/month on over-aeration. One retrofit later: equilibrium tech shrugs off biofilms, DO locks to ±0.4 ppb, blower runtime drops 28 %, and the plant earns its first “zero-violation” badge in a decade. Operators now calibrate from poolside via Bluetooth—turning sludge nightmares into lunch-break tweaks.

Technical Principles and Innovative Values

Innovation Point 1: True Equilibrium Magic – Unlike polarographic probes that guzzle electrolyte, the DL5PPB-300-0000-000 lets oxygen diffuse across a gas-permeable membrane until probe = process. Result: zero drift for 12 months—proven in a Belgian brewery to cut refill labor 92 %.
Innovation Point 2: One-Membrane Lifetime – PTFE cap lasts 3 years in raw sewage; snap-off design swaps in 90 s. A Florida power plant slashed sensor budget €24 k/year.
Innovation Point 3: Built-in PT1000 Brain – Temperature sensor welded inside the tip auto-corrects every reading to 0.03 ppm/°C—beating competitors by 40 % in diurnal swing tests.

Application Cases and Industry Value

A Toronto kraft pulp mill once bled $180 k yearly on over-limed whitewater. Engineers submerged twin DL5PPB-300-0000-000 probes into the headbox. Equilibrium lock nailed DO to 0.3 ppm; lime dosing dropped 19 %, brightness jumped 2 ISO points, and the mill pocketed its first carbon-credit check. Operators brag: “We now predict foam outbreaks 18 hours early.”

In a Shanghai pharma bioreactor fermenting insulin, four DL5PPB-300-0000-000 probes ride the agitator shaft. 60 s response caught a 0.8 ppm crash mid-batch—auto-boost saved 42 000 vials. Yield soared 8 %, FDA auditors smiled, and the plant’s validation file shrank by 180 pages.
