AM Bromley - Direct Tire Pressure-Monitoring System for Earthmover and Mining Vehicles

AM Bromley’s tire monitor system (TMS) is a direct tire pressure-monitoring system designed specifically for large off-road applications such as mining and construction, earthmoving, tire testing and research. The TMS can also be used as a wireless tire pressure gauge as it is very accurate over the pressure range. Sensors mounted inside each tire transmit tire pressure and temperature data to a receiver and display unit mounted in the cab.

Real-time tire management software

Good tire management improves the profitability of businesses, as tire maintenance and repair are a significant part of operating costs. The TMS will alert you in real time of any potential problems and help you to avoid accelerated wear, improve fuel efficiency and reduce tire failures.

TMS technology offers complete visibility of the tire pressure and temperature data in real time so you can keep tires running at optimum performance.

Tire monitoring system real-time data display

Showing real-time data to drivers gives you some unexpected benefits – the driver will know whether or not a tire with a slow loss of pressure will complete the shift or if there is sufficient pressure to drive to a convenient place for tire checking.

The TMS Operator Interface is mounted so the driver can see the tire pressure data and alarm status, and also displays tire pressure data for each allocated wheel and any alarm conditions. It logs tire data into memory for later recall and each record is time stamped. The real-time operator interface has the following features:

• Displays the status of each tyre including pressure
• Displays for up to six tyres
• Logs receptions with a real-time stamp
• Supports alarms: low pressure, high pressure, high temperature, low battery and reception timeout
• Connects to the TMS receiver

Tire monitoring system pressure and temperature sensor

The TMS Sensor is a small, battery-powered pressure and temperature sensor, which is mounted to each tyre using standard tire patch products and patching techniques. The sensor is patched to the inside of the tire on the low flex sidewall and monitors tire pressure and temperature, continuously transmitting data via the wireless transmitter to the TMS receiver. The sensor has the following features:

• Pressure range: 6psi to 185psi absolute
• Pressure accuracy: +/-2psi up to 150psi, +/-3psi 150psi to 185psi
• Temperature measurement range: -25°C to +125°C
• Transmissions: every five minutes and on change of pressure
• Every sensor has a unique ID code
• Transmission frequency: 433.92MHz
• Battery life: 4.8 years typically

Tire monitoring system receiver

The TMS Receiver is mounted in the vehicle cab and receives and decodes data from the TMS sensors. The receiver is powered by the vehicle supply, 12V/24V, and monitors the data from each sensor reporting any alerts. It is connected to the operator interface. In addition, it has the following features:

• Voltage supply: +10VDC to +36VDC
• Current consumption: 30mA typically
• Fused
• Operating temperature: -10°C to +55°C
• Up to four BNC terminated antennas can be connected
• Configured through TMS manager
• Transmission frequency: 433.92MHz

Tire monitoring system PC management program

TMS Manager, a PC program, enables you to configure the system, set the alarm conditions for each tire and to monitor the results.
