Reduce dust exposure with real-time cabin pressure monitoring

Cabin Pressure Explained

Intro to cabin pressure

Vehicle cabins are a critical control, isolating operators from harmful airborne dusts in the outside environment. To ensure cabins are working to protect workers, they require regular maintenance. Generally, this involves regularly replacing seals, cabin filters and maintaining positive pressure within the cabin. Testing the effectiveness of seals and the air-conditioning system requires the plant to be parked up for additional maintenance time.

By measuring air pressure inside versus outside of the cabin, you can determine how effective the cabin is at controlling dust from entering the cabin. This is a recognised method that can replace traditional subjective cabin testing with an objective, real-time solution that informs planned maintenance.

Information on how the cabin performs is also valuable for informing personal exposure monitoring exceedance investigations.

Benefits explained

How does it work

Our solution involves placing a wireless sensor inside the cabin to measure differential pressure (inside and outside of the cabin). The sensors regularly feed data directly to the cloud over a cellular connection, providing you with real-time information displayed in a dashboard that can be accessed anytime, anywhere.

Sensors can be installed into as many cabins as required, with gateways (data receivers) positioned throughout the site to receive the data. This replaces the traditional after-the-fact and subjective methods of monitoring cabin integrity, and replaces them with an objective, real-time solution.

GCG will also provide additional data analysis in a monthly report outlining potential worker exposure and maintenance insights. GCG specialists analyse the real-time data and provide insights to minimise the impact to maintenance personnel.

GCG will also provide additional data analysis in a monthly report outlining potential worker exposure and maintenance insights. GCG’s qualified occupational hygienists are available to provide additional support and advice upon request, or when we see trends in the data that we think you need to be made aware of.

Real time explained

The Dashboard

The dashboard is automatically updated with the most current data available and provides you with instant access to critical information.

This real-time information is useful for identifying risks as they’re occurring, identifying emerging trends and developing maintenance schedules.

The solution includes GCG specialists analysing the real-time data and providing insights to minimise the impact to maintenance personnel.

Devices

Device Specs

The solution uses differential pressure sensors to take the measurements and cellular gateways to capture and transmit data to the cloud.

Differential Pressure Sensor:

Battery-powered (AA) +3 years

Wireless Sensor

Measures 140 x 90 x 141 mm

Cellular Gateway (data receiver):

Can be powered by 12V power supply within mobile plant

Can be powered by 240V charger if mounted at go line or crib huts

Back up battery power

Measures 127 x 96 x 38mm

Installation Gallery

Installation of the sensors and gateways (data receivers) is simple and takes less than ten minutes per cabin. The sensors operate wirelessly and are easily mounted using screws or zip ties and 3M tape.

Tubing is run through existing grommets for external sampling and a filter is added on external tubing to prevent dust/water ingress.
