Truck System Technologies TST-507-INT-S1 Internal TPMS Sensor with Strap

The Truck System Technologies TST-507-INT-S1 is a single internal tire pressure monitoring sensor designed for use with TST 507 Series TPMS systems. This sensor mounts inside the tire using an included hose clamp strap, providing more accurate temperature readings compared to external valve stem-mounted sensors.

Key Features:

• Internal mounting design for superior temperature accuracy
• Real-time tire pressure and temperature monitoring
• Wireless transmission at 433.92 MHz frequency
• Pressure monitoring range: 0-196 PSI
• Operating temperature range: -4°F to 176°F (-20°C to 80°C)
• Compact dimensions: 2.75 inches long x 1.25 inches wide x 0.625 inches thick
• Lightweight construction at just 1.38 ounces
• Compatible with wheel rims up to 22.5 inches in diameter

Installation:

• Mounts to center wheel hub using included stainless steel hose clamp strap
• Position sensor 180 degrees from tire valve stem
• Simple screwdriver installation—tighten clamp and trim excess strap
• Must be installed during tire mounting by a professional

This replacement sensor is ideal for RVs, trailers, commercial trucks, and heavy-duty applications where theft prevention and accurate monitoring are critical. Each sensor pairs wirelessly with TST 507 Series color monitors and can be programmed to specific tire positions. The TST system supports monitoring up to 110 tires simultaneously, making it perfect for fleet vehicles and multi-trailer setups.

What's Included:

• One TST-507-INT-S1 internal tire sensor
• Stainless steel mounting strap (hose clamp style)

Note: Requires TST 507 Series color display monitor (sold separately). Sensor provides pressure accuracy within ±3 PSI when compared to a digital gauge. Battery life varies based on usage conditions.
