Essae has been developing, testing, and installing weigh in motion systems for a number of years. We listen to you, the customer, to develop hardware and software that does what you want it to do. This web page is designed to help you learn about weigh in motion and to choose a system that is right for your application.Weigh in Motion Components
Each weigh in motion system will consist of the following components. These components will vary with the type of system you require.
Types of Weigh in Motion
- Weight sensors - the hardware that weighs the vehicle. The type of sensor depends on your system requirements - portable or permanent installation. Please see below.
- Cabling - connects the weight sensors to the computer.
- Computer Interface - data acquisition electronics that convert the scale readings to real weight. Click here for information on the interface, and computer requirements.
- PC Software - does calculations on the weight readings and stores the data.
The two major types of weigh in motion are portable and permanent. Both systems have the same basic components.Portable
In a portable system, the computer, and weight sensors are the portable part. A portable system is able to be set up in under 10 minutes, and can be used on any flat, hard, and level surface. This type of system can be used to weigh vehicles where a permanent installation is not feasible, or where the system needs to be moved frequently to different locations.Permanent
Permanent systems are usually installed where the scale needs to become part of the road, and the weighing is integral to other processes. Locations such as border crossings, toll lanes and shipping gates are typical applications for permanent systems.
