WEIBER designs and manufactures standard as well as customized water spray test chamber for evaluating various automotive, electrical and electronics items under water, rain or shower conditions. The chamber interrogates the performance of parts when subjected to water droplets.

The system is based on the IP X5, X6 specification requirements, and can also accomplish individual automaker’s tests, as well as electrical-enclosure tests.

Our system uses multiple control solenoids to vary the water's spray volume/pressure. A holding tank prepares the water to the desired temperature, if required. A pump ensures the water is delivered in the proper pressure range.

    Weiber provides better automatic controls for the chamber by integrating HMI and PLC together. This special feature is compelling alternative to traditional methods and provides a simplified, reduced cost control system architecture.
    It works by following operating steps:

    • Sensors measure the physical quantity like temperature and convert them to electrical signal
    • The actuation device acts upon that electrical signal
    • At HMI interface between operator and chamber occurs.
    • The machine operates with the logic design controls controlled by software.
    • This signal is sent to the chamber by logic control devices and the chamber operates.

    Basic features of HMI+PLC:

    • Processor of 1.6 GHz: High clock speed processing PLC that enables speed up processing to the functions. With 1.6GHz processing speed, the PLC system is capable of multitasking, processing of large data volume, and high performance.
    • Audio Output Alarm: Audio alarm alertin case of failures in any of the component controlling functions.
    • 256 MB of RAM: PLC of 256Mega Byte memory for running programmes offers high memory space for installing of more programs
