he WS-30 is an hazardous area compliant device whom function is to constantly monitor the weight of the collected sample and it is designed to work seamlessly with the whole Autocontrol sampling systems range.The assembly, built to be compliant with the requirements of an hazardous area environment, is composed by the weighing platform, the safe area intrinsically safe interface and, optionally, by a power supply. All the above is supplied installed in appropriate EEx-d box, suitable to be interfaced with an external sampling system.
The sampling system can be equipped with up to four WS-30 weighing systems.
The WS-30 weighing platform is designed as a stand-alone sub system, easy to calibrate and built with the most modern weight transmitters and safety devices in order to provide the most accurate linearity signal and the higher accuracy.
When interfaced with an Autocontrol controller the weight is red digitally, exploiting in this way the maximum accuracy thanks to a reduced number of analogic conversions across the acquisition chain.
The “off centre” type mono-cell allows to obtain always a precise measurement even with an unbalanced weight on the platform.
The main benefits of adding a WS-30 to a sampling system are the followings:
Possibility to compute a Performance Factor of the sampling operation, as required by API8.2, ISO3171 and ASTMD4177 standards.
Real time monitoring of the sampling system performances, with the possibility to detect any sampling problems in early stage.
