Liquefied Petroleum Gas (LPG) is widely used across Australian industrial and commercial environments due to its efficiency and versatility, but it also presents a serious explosion and fire risk if leaks go undetected.
ProDetec supplies and supports high-performance LPG gas detectors designed to identify leaks early, protect people and assets, and support Australian compliance obligations. With decades of experience in gas detection across high-risk industries, we deliver reliable LPG gas leak detector solutions engineered for real-world conditions.
From fixed plant installations to portable safety equipment, ProDetec provides end-to-end LPG gas detection solutions across Australia, backed by local expertise, calibration services, and long-term support.
An LPG gas detector is a safety device designed to identify the presence of leaked LPG gases – primarily propane and butane – before they reach dangerous concentrations. These detectors continuously monitor air quality and trigger visual, audible, or system alarms when LPG levels approach or exceed predefined thresholds.
Because LPG is heavier than air, leaked gas tends to accumulate at ground level or in low-lying areas, increasing the risk of ignition. A properly selected gas detector LPG system provides early warning, allowing operators to isolate gas supply, ventilate the area, and prevent escalation into fire or explosion events.
Modern LPG gas detection systems use proven sensor technologies to measure combustible gas concentrations relative to the Lower Explosive Limit (LEL), ensuring rapid response and reliable protection.
Different environments require different sensor technologies. ProDetec supplies LPG gas detectors using multiple detection principles to suit site-specific risks and operational requirements.
Catalytic bead sensors are one of the most widely used technologies for LPG detection. They work by oxidising combustible gas on a heated sensor element, producing a measurable change in resistance.
Catalytic sensors remain a trusted option for fixed LPG gas leak detector installations in many industrial environments.
Infrared sensors detect LPG by measuring the absorption of infrared light by hydrocarbon gas molecules. These sensors do not rely on combustion and offer long-term stability.
IR technology is commonly used in fixed installations, including systems based on an infrared hydrocarbon gas detector, where reliability and low lifecycle cost are critical.
Semiconductor sensors detect LPG through changes in electrical conductivity when gas is present.
These sensors are often used where cost sensitivity and basic LPG detection are the primary drivers.
Fixed LPG detectors are permanently installed and provide continuous, automated monitoring. They are ideal for:
Portable or handheld LPG detectors are better suited for:
Most comprehensive safety strategies combine fixed systems with portable units to provide layered protection. ProDetec supplies both options and advises on the correct configuration for each application.
LPG gas detection in Australia is governed by multiple standards and regulatory frameworks, including:
Compliance requires not only installing the correct LPG gas detector, but also maintaining it through documented inspection, testing, and calibration.
Correct installation is critical to effective LPG gas detection.
Because LPG is heavier than air, detectors are typically installed close to floor level, around 300-500 mm above ground. However, every application is different, and this should be treated as a general rule of thumb only. Final placement should always consider airflow patterns, site layout, and specific risk conditions.
Sensors should be positioned near potential leak points – valves, regulators, joints, and appliances – while avoiding dead air spaces.
LPG detectors are commonly integrated with automatic shut-off solenoids, alarms, ventilation systems, and control panels to enable rapid response when a leak is detected.
ProDetec provides engineering guidance to ensure installations are fit for purpose and compliant.
Routine calibration is essential to ensure accuracy and reliability. Australian standards and manufacturers typically recommend calibration every 3-6 months, depending on usage and environmental exposure.
ProDetec offers full gas detector calibration services, supported by certified technicians, traceable calibration equipment, and replacement sensor stock on hand across every state in Australia. Our local support teams ensure fast turnaround, reduced downtime, and ongoing compliance while extending sensor life and minimising false alarms.
ProDetec supplies a comprehensive range of LPG gas detection equipment for industrial and commercial environments, including:
Our solutions are sourced from trusted global manufacturers, we are also supported locally as part of our broader portfolio of gas detectors in Australia. We also support complex sites requiring specialised detection, such as hydrogen detector, SF6 gas detector, or H2S gas detector integration within a single safety framework.
LPG hazards demand reliable detection, correct installation, and ongoing support. ProDetec partners with customers to reduce risk, protect people, and ensure confidence in their gas safety systems.

LPG gas detectors should be installed close to floor level near likely leak sources, as LPG is heavier than air and accumulates in low areas.
No. LPG detectors are designed for propane and butane. Natural gas (methane) requires a different detection technology and sensor placement strategy.
Most LPG gas detectors require calibration every 3-6 months, depending on environmental conditions and manufacturer recommendations.
LEL stands for Lower Explosive Limit – the minimum gas concentration that can ignite. LPG detectors typically alarm at a percentage of the LEL to provide early warning.
Requirements depend on application and jurisdiction, but LPG detection is often mandated by safety regulations, Australian Standards, insurers, and risk assessments in industrial and commercial settings.
