General Description

TPMS - OTR is specifically designed for wheel constructional machinery. The system consists of a monitor, transmitter and hand tool (optional).

Product Features

  • System functions include low pressure alarm, fast leak alarm, pressure programming function.
  • Connects to the vehicle for continuous power to ensure full-time monitoring.
  • Large pressure range, suitable for engineering vehicles.
  • Monitor up to 38 tyres.
  • Records tyre pressure, temperature and alarm information, which can be downloaded via USB.

Alarm Functions

  • High Temperature Alarm issued when tyre temperature exceeds 90°C.
  • Low Pressure Level 1 Alarm issued when tyre pressure is 12.5% lower than the standard pressure.
  • Low Pressure Level 2 Alarm issued when tyre pressure is 25% lower than the standard pressure.
  • Low Pressure Level 3 Alarm issued when tyre pressure is 50% lower than the standard pressure.
  • High Pressure Alarm issued when tyre pressure is 25% higher than the standard pressure.
  • Fast Leak Alarm issued when pressure inside the tyre drops more than 3psi within 12s.
  • Transmitter Trouble Alarm issued when transmitter fails to work or there is RF interference.
