1、 Overview
SWJ1/2 type water level monitor receives the analog signal sent by the liquid level transmitter, and sends it to the CPU for processing and calculation through A/D conversion. It visually displays the water level value, outputs four alarm outputs, one analog quantity, and RS485 communication. The range, altitude, and alarm value can be set arbitrarily by pressing the key.


2、 Features
■ Single chip microcomputer system generates measurement timing pulse after internal frequency division, with measurement accuracy unchanged for a long time;
■ Four output signals are amplified to drive the relay output, of which four action points and alarm values can be set;
■ The advanced WATCHDOG and voltage monitoring circuit can monitor the working condition of the computer
