P.S.I. Introduces Digital ThermALERT™ With Real-Time Visibility of Wheel-end Temperatures


San Antonio, TX (February 26, 2023) Today, during a press conference held in conjunction with TMC's 2023 Annual Meeting & Transportation Technology Exhibition, Pressure Systems International (P.S.I.), celebrating its 30th anniversary, introduced Digital ThermALERT®, a sensor that provides real-time wheel-end temperature visibility through a telematics communication portal.

P.S.I.’s patented standard ThermALERT alerts users to elevated wheel-end temperatures that could cause damage, wheel loss or fire and excess roadside calls if not addressed early. It has been standard on the P.S.I ATIS product since 2017 saving fleets unnecessary costs associated with elevated wheel-end temperatures.

Digital ThermALERT announced today, provides all the benefits of traditional ThermALERT plus full visibility of wheel-end temperatures thru P.S.I.’s TireView® LIVE™ portal or through one of their telematics integration partners such as Road Ready from Clarience Technologies.

The real-time reporting from Digital ThermALERT aids in identifying the normal wheel-end operating temperature of a user’s equipment and the ability to analyze wheel-end history. It can also help identify equipment or maintenance issues such as a dragging brake or bearing issue that can be scheduled in for service before damage can occur. The alert activation level can be customized by the user depending on equipment and personal preference.

Digital ThermALERT is optimally located to read the temperature inside the spindle end at the wheel bearings and minimizes the effects of external thermal influences. The sensor has a replaceable battery with a conductor wire that is fed through the axle end and attached to a modified PSI spindle plug.

Also introduced during the P.S.I. press conference:

  • ATIS/MTIS Driver Video: Driver video explains system operation and what to do when the system indicator light illuminates. It’s viewable on mobile via QR code or desktop. A new decal with a QR code can be ordered from P.S.I. for retrofit placement on existing assets. New orders will receive an updated system decal with the QR code.

  • TireView LIVE Mobile App (April 1, 2023 Launch): Available for Apple/Android devices with all the features and benefits of the TireView LIVE portal in the palm of our hand:

    • Drill down by vehicle type, terminal or region

    • Data analytics platform for thorough tire analysis

    • Aid pre-trip tire inspections and post-trip analysis

    • Sort and share data to make best decisions about PM and in-transit repairs

    • Convenient over-the-air (OTA) updates and sensor pairing by capturing sensor QR codes using mobile device camera
