WP401A Aluminium Case Integrated LCD Negative Pressure Transmitter ndi mtundu wofunikira wa chida choyezera kuthamanga kwa analogi. Bokosi lapamwamba la aluminiyamu yolumikizira chipolopolo limapangidwa ndi amplifier circuit ndi terminal block pomwe gawo lakumunsi lili ndi zinthu zapamwamba zowonera. Kuphatikizika kokhazikika kwa boma komanso ukadaulo wodzipatula wa diaphragm kumapangitsa kukhala chisankho chokondedwa pamitundu yonse yamasamba owongolera makina.
WP401A Pressure Transmitter ili ndi zizindikiro zosiyanasiyana zotuluka kuphatikizapo 4-20mA (2-waya), Modbus ndi HART Protocol. Mitundu yoyezera kupanikizika imaphatikizapo gauge, absolute and negative pressure (ochepera -1bar). Chizindikiro chophatikizika, kapangidwe kakale ka umboni ndi zida zotsutsana ndi dzimbiri zilipo.
