Wabco 4410441020 ECAS Pressure Sensor
Description
The Ecas-Pressure Sensor, Cvs by
Wabco is a critical component within air brake systems, specifically functioning as a relay valve. It is used to monitor and regulate air pressure, ensuring reliable braking performance in commercial vehicles. This sensor features a piezo-resistive design with a measuring range of 0 to 10.00 bar and a maximum operating pressure of 16.0 bar. It boasts high accuracy with a linearity of 0.3% FS and hysteresis of 0.2% FS, along with robust protection with IP6K7/IP6K9K classification. The sensor's dimensions are 29 x 30 x 52 mm and is manufactured in Denmark. This sensor is an OE specification device with a Bayonet DIN 72585 A1-3.1-Sn/K2 electrical connection.
Key Features & Benefits
This sensor’s main job is to monitor the air pressure within your vehicle’s Electronic Controlled Air Suspension system – that’s what ECAS stands for. It's constantly reading that pressure and sending a signal to the vehicle’s computer. It doesn’t control anything directly, it just reports the information. It’s checking pressure in the air springs, essentially. There are usually several of these on a vehicle, each monitoring a specific part of the system.
Think of your air suspension as being like really strong, adjustable springs. The ECAS system uses air pressure to control ride height, and to keep the vehicle level, especially when you're hauling a load or towing. This sensor is the eyes of the system; it tells the computer what’s happening with that air pressure. The computer then uses that information to adjust the suspension as needed. It’s a crucial part of maintaining a smooth ride and safe handling.
Symptoms, Risks & Replacements
If this sensor goes bad, the computer gets inaccurate information. That can lead to a lot of things – the suspension might not raise or lower correctly, it could constantly cycle trying to maintain height, or you might even get warning lights on your dash. You’ll notice if it’s causing a particularly rough ride, or if the vehicle seems to be sitting unevenly. It basically acts like a shield, protecting the whole system from operating incorrectly. A bad reading can ultimately cause other, more expensive parts of the air suspension to wear out prematurely, or even fail. You can often find these sensors at places like Fixparts Online, and getting a good one quickly can save you a headache down the road.
