In today’s industrial landscape, timely detection of hydrocarbon leaks—especially in cramped or hazardous spaces—can mean the difference between operational safety and environmental catastrophe. Enter the Naftosense FLD-HCSP: a miniature, stainless-steel-encased hydrocarbon leak detection probe designed to reliably sniff out crude oil, refined fuels, and vapors, even in the most unforgiving conditions.
What Is the FLD-HCSP?
The FLD-HCSP is a compact, passive hydrocarbon leak detection sensor. Built for high-risk industrial environments, it measures only 3.74 inches (95 mm) in length and 0.59 inches (15 mm) in diameter. Despite its small footprint, this device punches far above its weight class, offering robust performance, minimal maintenance, and quick detection across a broad temperature spectrum—from -40°F to 185°F (-40°C to 85°C).
Naftosense designed this sensor to interface seamlessly with its acquisition modules and intrinsically safe field boxes, making integration into third-party systems straightforward via analog outputs, dry contacts, or serial communications.
Real-World Applications
The FLD-HCSP thrives where space is limited, danger is present, and precision is critical. Common applications include:
- Tank interstitial space monitoring
- Leak detection in dual-wall piping systems
- Detection in sump pits, pump seals, and leak detection wells
- Fuel containment monitoring in retail and downstream facilities
- Rotating equipment (machine shafts, pumps) where conventional sensors may fail
It also excels as a fume or vapor detector, capable of identifying hydrocarbons diffused through soil or air with minimal false alarms—making it ideal for early-stage leak warnings.
Key Features That Set It Apart
1. Fast, Reliable Detection
The FLD-HCSP detects various hydrocarbons in as little as 20 seconds (gasoline and jet fuel) to under 10 minutes(heavy crude), depending on the substance. This speed aligns with or exceeds standards such as FM7745.
2. Reusability and Ease of Maintenance
The sensor is reusable and cleanable, thanks to an optional quick-disconnect jumper cable. This significantly reduces lifecycle costs and supports a rapid return to service after contamination.
3. Total Safety in Hazardous Zones
Designed as a passive element, the FLD-HCSP carries Class I, Division 1, and Zone 0 hazardous location certifications under ATEX, IECEx, and U.S. standards—allowing deployment in the most stringent environments without risk of ignition.
4. Long Operating Life
The materials used in the sensor have undergone natural aging tests, with an expected service life of over 30 years at 104°F (40°C). Naftosense backs this up with a 10-year warranty, providing peace of mind in long-term installations.
5. Harsh Environment Durability
Rated IP68, the FLD-HCSP is fully submersible and suitable for direct burial—critical for leak detection around underground tanks, lines, and containment systems.
Integration and Connectivity
Naftosense simplifies integration with approved analog or digital field modules, enabling users to deploy the probe in either wired or wireless configurations. When paired with intrinsically safe acquisition modules, users can achieve real-time monitoring, alerts, and system-wide diagnostics—all while staying compliant with PHMSA (Pipeline and Hazardous Materials Safety Administration) guidelines.
The sensor supports up to 300 feet (90 meters) of cable distance, offering flexibility in design and layout, especially in retrofits or remote field deployments.
