TST TRUCK SYSTEM TECHNOLOGIES TPMS 2 Flow‑Thru Metal Valve Sensors — Real‑Time Pressure & Temperature

The TST 507 is a dual-sensor Tire Pressure Monitoring System with flow‑thru metal valve sensors designed to give caravan, motorhome and campervan owners continuous, on-road tyre pressure and temperature insight.

Installed on metal valve stems, the TST 507 uses two exterior flow‑thru sensors to transmit real‑time tyre pressure and temperature data to a compatible display or receiver. The system helps drivers notice slow leaks, rapid pressure loss or abnormal heat build-up so they can address issues before they complicate a trip. Sensors are built for heavy‑duty use and repeated mounting on metal valve stems common to caravans and larger recreational vehicles.

How does the TST 507 install on metal valve stems?

Installation is straightforward: remove the factory cap, thread the flow‑thru sensor onto the metal valve stem and hand‑tighten. The design allows air to be added or adjusted without removing the sensor assembly, preserving convenience during roadside inflation.

• Flow‑thru threading fits standard metal valve stems used on caravans and motorhomes
• Hand‑tighten seal with included torque instructions to prevent leaks
• Allows inflation while sensors remain attached for quick tyre pressure correction
• Compact sensor body minimises exposure to wheel debris and impacts

What real‑time data will I see and why does it matter?

The TST 507 reports tyre pressure and temperature for each fitted wheel, delivering continuous feedback that helps spot issues early. Stable pressure improves handling and fuel efficiency; tracking temperature can indicate bearing or brake-related heat before component damage occurs.

• Live tyre pressure readouts for accurate inflation monitoring
• Temperature monitoring to identify excessive heat trends
• Alerts for rapid deflation or pressure thresholds you set on the receiver
• Data transmission suited to caravan and motorhome driving conditions

How durable are the flow‑thru sensors for long trips and varying weather?

TST designed the 507 sensors for the rigours of recreational vehicle use, with materials and seals that resist moisture, road salt and vibration. Their flow‑thru form factor protects the valve interface while allowing normal servicing of tyre pressure at stops.

• Robust housing built for long‑distance touring and repeated use
• Seals engineered for wet and cold conditions common to road travel
• Resistant to wheel vibration and common environmental contaminants
• Replacement parts and guidance available from Truck System Technologies

Which display or receiver works with the TST 507 sensors?

TST 507 sensors are compatible with Truck System Technologies receivers and displays that support their transmission protocol. Confirm compatibility with your TST display model or consult product documentation before purchase to ensure seamless pairing.

• Pairs with TST receivers designed for two external sensors
• Check firmware versions and pairing steps in the manual for quick setup
• Some third‑party receivers may require protocol matching—verify beforehand
• Replacement or expansion options available from the brand for multi‑wheel setups

Who is this for? The TST 507 is aimed at caravan, motorhome and campervan owners who prefer metal valve stems and want a durable, in‑use monitoring solution that stays mounted while refilling tyres. It suits travellers who value continuous tyre condition visibility during long journeys, DIY installers comfortable hand‑fitting valve sensors, and fleet operators wanting simple, replaceable sensors for recreational vehicles.
