ตัวควบคุมเครื่องส่งสัญญาณ WJK ของ JIANGHE XIAN, เครื่องส่งสัญญาณควบคุมระดับรวมกับการวัด

Overview
WKD liquid level control transmitter is to measure the liquid level of imported micro range dry ceramic pressure sensor. The instrument in measurement, display, remote alarm, as a whole, the liquid level can be converted into a standard signal 4~20mA current signal, and can send on the upper limit, lower limit of three alarm signal, the alarm value of the full range of adjustable for liquid level measurement, bearing and back to the tank system.
