Aerosol pressure controller PA-X
Electronic Pressure Gauge
The PA-X is an electronic pressure gauge designed specifically to monitor the internal pressure of aerosols during production. It measures the pressure of the propellant gas inside the aerosol can by connecting the spray nozzle directly to one of the included adapters—without drilling into or damaging the can.
This measurement is critical in the manufacture of aerosol products: insufficient pressure causes the spray to malfunction, while excessive pressure poses a safety risk. Checking the propellant pressure is one of the regulatory inspections required by ADR standards and the European directives applicable to aerosols (Directive 75/324/EEC and its amendments).
The PA-X system consists of a flush-mounted diaphragm pressure sensor integrated into a portable console powered by a rechargeable 12V battery. It has a measurement range of up to 10 bar, with an accuracy of 1% of full scale, and can store up to 200 readings in its internal memory.
Description
Uses and Applications
A test that takes just a few seconds
It’s easy to use: simply press the aerosol nozzle into one of the three adapters provided (1 male, 1 female 4 mm diameter, 1 female 3.4 mm diameter), which cover the standard sizes available on the market. The pressure is displayed instantly on the LCD screen of the XA Version P console. The peak mode records the maximum value reached, allowing for easy reading after the test.
Applications in production
The PA-X is used for incoming quality control (inspection of received aerosols), production monitoring (batch-by-batch pressure monitoring), and outgoing quality control (validation prior to shipment). It detects aerosols that are underpressurized, overpressurized, or whose pressure drifts over time during storage.
Custom adapters
For non-standard chimney-style sprayers, ACRN offers custom adapters. Please contact our team with the dimensions of your fireplace to receive a customized solution.
Why check the pressure of an aerosol can
The internal pressure of an aerosol is a critical factor that determines both the product’s safety and the quality of its use. It depends on the amount of propellant gas introduced during filling, the storage temperature, and the type of propellant used (butane, propane, DME, CO₂, nitrogen, etc.).
A safety issue above all else
A pressurized aerosol can explode if exposed to heat or accidentally punctured. The ADR regulations (on the transport of dangerous goods) and European Directive 75/324/EEC impose strict pressure limits on aerosols placed on the market. Failure to comply with these limits will result in the manufacturer being held liable and may lead to the product being recalled.
A matter of product quality
An aerosol can with too little propellant will work properly at first, but the pressure drops more quickly—the spray becomes unusable before the product is used up. For spray-formulated cosmetics, pharmaceuticals, or food products, this constitutes a major quality defect and a source of customer complaints.
A challenge related to manufacturing repeatability
Systematic batch-by-batch pressure checks make it possible to detect issues at the filling station (such as nozzle wear or variations in the amount of gas injected) before they affect a large volume of production. This is a process control measure as defined by ISO 9001 and GMP guidelines.
Calibration and Regulatory Compliance
The PA-X comes with a COFRAC-accredited calibration certificate valid up to 9 bar. Optionally, a COFRAC-accredited certificate for pressures up to 10 bar is available, as well as annual calibration at the ACRN metrology laboratory.
Metrological traceability of the PA-X is essential for aerosol manufacturers subject to regulatory controls: European Directive 75/324/EEC requires pressure checks on aerosols placed on the market, and audits by the competent authorities (DGCCRF, certification bodies) may require proof of the traceability of the measuring instruments used.
Annual calibration by ACRN ensures the continuity of this traceability and the compliance of your quality control process with ISO 9001 requirements and your customers’ quality standards.
