S
Safety
Real-time detection of slow and fast leaks, overheat and overpressure. Alarm output can be wired into an interlock to limit speed on low pressure.
Products / TR100
TR100 Industrial TPMS
An industrial-grade tire pressure and temperature monitoring system for port machinery, mining trucks and heavy-duty vehicles. Built to talk to the machine's own controller over CAN, RS485, Profinet, RS232 or Modbus — and to reach the cloud when you need it.
Four parts, one self-developed chain
| Component | Function | Location |
|---|---|---|
| Sensor | Reads pressure and temperature, transmits over 433.92 MHz | Valve stem / rim, inside or outside the tire |
| Receiver | Collects all sensors and outputs to the vehicle bus or a display | Electrical cabinet or cab |
| Repeater | Extends radio coverage past long chassis and metal structures | Mid-chassis or unobstructed points |
| Display | Shows every wheel's pressure and temperature in real time | Cab |
Four reasons fleets fit it
E
Economy
Correct inflation extends tire life by a reported 20–30 %, cuts fuel burn and avoids unplanned downtime.
F
Efficiency
Replaces manual walk-around checks with continuous automatic monitoring and visual alarms.
I
Intelligence
Multi-bus output plus an optional 4G gateway for fleet dashboards, history and utilisation reporting.

What the hardware looks like
Sensor variants, the radio receiver and repeater, and the 7" cab display. Threaded brass valve bodies are available for external fitment; strap and internal versions cover the other mounting cases.
External valve sensor — brass thread, replaceable battery, IP67/IP68.
Strap-mounted sensor — for rims where no valve-stem fitment is possible.
Internal valve sensor — sealed in-tire mounting, protected from impact.
Receiver — up to 250 sensors, multi-bus output, 9–52 V DC.
Repeater — ≥ 100 m relay, IP67, for long chassis.
7" cab display — 800 × 480, DC 9–35 V, IP65.
