TWD-1500 Commercial & Fleet — Heavy-Duty Trailer Monitoring

Commercial-Grade Axle Monitoring + TPMS The TWD-1500 Commercial is an axle temperature monitoring system and TPMS built for heavy-duty and fleet applications. Dually axles, quad axles, multi-wheel commercial setups — it monitors every bearing and every tire across your entire rig. When you are hauling professionally, failure is not an option. When you are hauling professionally, one hidden bearing failure or tire blowout can cost thousands in damaged cargo, missed deliveries, and DOT violations. The TWD-1500 catches it before it happens. No Repeaters. No Missed Broadcasts. Commercial rigs mean longer trailers and more wheels — exactly where traditional TPMS systems lose signal. The TWD-1500 uses a Bluetooth 5 mesh listening network that covers your entire trailer without repeaters or boosters. Every sensor, every wheel, every broadcast heard — no matter how long your rig. Missed TPMS updates are a thing of the past. TPMS sensors are rated for up to 250 PSI The highest of any Bluetooth TPMS system on the market. Most budget systems cap at 87 PSI, and even premium RV systems top out around 188–232 PSI. This means the TWD-1500 works with every trailer tire on the road, including Class A RVs running 110 PSI, heavy commercial setups, and high-pressure specialty tires. IP67 Waterproof — Built for the Job Site Every component of the TWD-1500 is IP67 rated. Rain, mud, salt, dust, pressure washers — your monitoring system keeps working in the conditions commercial trailers actually face. No babying required.
