Reliable Pressure Sensors for Air Suspension

There is no single correct PSI for every air suspension system. Pressure changes with vehicle configuration, suspension design, axle loading, cargo distribution, and operating conditions. For load monitoring, the useful measurement is the relationship between pressure and actual weight after proper calibration. Follow the vehicle manufacturer’s operating requirements and use a calibrated onboard scale system to interpret pressure as weight.

An air pressure sensor measures pressure within an air-ride suspension system and sends that reading to a compatible display or onboard scale system. After calibration, the system uses pressure data to estimate weight carried by the suspension. This gives drivers and fleet teams practical visibility into axle-group, gross vehicle, or net weights without relying solely on external scales.

Yes. When correctly installed and calibrated, air suspension pressure sensors provide onboard weight estimates that help operators check loads before leaving a site or approaching a scale. They support better load distribution and payload decisions, which can reduce the likelihood of overweight conditions and related fines. Final compliance remains the operator’s responsibility and should follow applicable regulations.

TruckWeight offers wireless onboard scale technology designed to avoid complicated wires, cables, and electrical connections. This approach can simplify installation on compatible commercial trucks, tractors, and trailers with air-ride suspensions. Wireless sensor information can be viewed through compatible TruckWeight displays and, where configured, shared through TruckWeight Analytics for remote fleet visibility and reporting.

Accuracy depends on correct installation, calibration, suspension condition, vehicle configuration, and load distribution. TruckWeight identifies its patented air suspension sensor technology with stated accuracy from 0.3% to 1%. Because operating conditions can affect readings, fleets should establish calibration and verification routines and use the system as part of their broader payload and compliance-management process.

TruckWeight solutions support commercial trucks, tractors, and trailers across air and spring suspension configurations. Air suspension pressure sensors are intended for compatible air-ride applications, while strain gauge options address mechanical or spring suspensions. Selecting the appropriate sensing technology depends on the vehicle, suspension type, desired weight readings, and the fleet’s display or data-integration requirements.

TruckWeight’s Full Remote Calibration service uses cloud-based connectivity to support calibration of onboard scale sensors and system configuration from a remote location. It can help back-office teams maintain calibration records, identify equipment that may need maintenance or recalibration, and support quality-control workflows. The available approach depends on the installed TruckWeight system and its connected service configuration.

Yes. TruckWeight Analytics is designed to connect onboard scale weight data with cloud platforms and telematics APIs. The smart data pipeline supports real-time data access and dissemination, including technologies such as Google Firestore, BigQuery, and PubSub. This can help drivers, dispatchers, maintenance teams, and back-office staff work from more timely weight information.
