Frequently Asked Questions

What is iWeigh® for Trailers?
iWeigh® is the industry’s most advanced on-board scale platform.   iWeigh® for Trailers is a flexible and very accurate trailer scale, delivering suspension weight data directly to most smart devices.  This allows drivers to see the trailer weight while loading from up to 100 feet away, in real time.  iWeigh® is also “scalable” through over-the-air updates to include future features and networking capabilities.
How does iWeigh® work?
iWeigh® uses sensors to measure air pressure (for air ride suspensions) or a highly-engineered deflection sensor to measure micro-flexing of the axle group (for mechanical suspensions). By calibrating the system with known empty weight at time of the trailer weighed empty and known loaded weight at time of loaded weights, iWeigh® uses the saved calibrated data to accurately calculate and display the current weight of the trailer.

The scale must be calibrated before use. iWeigh® can display weights in pounds or kilograms.

After calibration, simply view weights on the Air-Weigh app or through telematics. The weight data will update in real time.
How accurate is iWeigh®?
iWeigh® boasts industry-leading accuracy. For air-ride suspensions, it is 99% accurate (+/- 300 lbs.), while for mechanical suspensions, it offers 97% accuracy (+/- 900 lbs.).

iWeigh® displays weights in 20lbs. or 20kgs. increments.
What trailer suspension types does iWeigh® for trailer work with?
iWeigh® is designed for both air ride suspensions and most mechanical suspensions.
How many sensors can iWeigh® accommodate?
iWeigh® can accommodate up to 3 air sensors and 4 deflection sensors at once.
Do I need to recalibrating iWeigh® for trailer for accuracy?
Generally, no.  Once you've calibrated iWeigh® with accurate empty and loaded weights, there's no need for recalibration. The system will continue to provide accurate weight readings. If the suspension undergoes significant damage, wear & tear, or changes such as replacing a leveling valve or air bag, a new recalibration is recommended.

iWeigh® is powered by tapping into the trailer power. iWeigh® trailer kits includes an ABS T-breakout for quick and easy access to power and ground.  The ABS T-breakout is compatible with most major trailer wire harness manufacturers.
How far is iWeigh® communication range?
The range for iWeigh® is up to 100 feet in line-of-sight.
How long is the average iWeigh® installation?
This time will vary depending on sensors and suspensions set up. An average iWeigh® installation is around1 – 2 hours for air sensor installation, and calibration is 1-2 hours. Mechanical deflection sensors may take 3 to 4 hours, with 1 to 2 hours for calibration.
How do I assign a unique name to my iWeigh® scale?

PEOPLE SAY THE NICEST THINGS

Mike VanderPloeg
Operations Supervisor

With EVs, the cars are getting heavier. With every electrification point of a vehicle, it’s 200 to 300 more pounds vs. a gas version. A hybrid is 200 to 300 pounds more than the gas car and a full EV is another 200 to 300 pounds. That makes these scales all the more critical.

We use Air-Weigh scales to ensure that we pick up a full load every time. In fact, the first big haul after we installed them paid for the scales! I also like the peace of mind of knowing we won’t get an overweight ticket.
