Overview

The JCC series liquid level switch consists of two parts: sensors and instruments, covering basic functions such as measurement, display, alarm, transmission, and control of liquid level instruments. Can be used as a continuous measurement level gauge;Can be used as a low low, low, high, high high four point alarm switch; Can be used for liquid level high/low limit control and abnormal over limit alarm; Widely used for liquid level measurement, alarm and control.

Technical Specifications

Working power supply: 5-30VDC, 3.3VDC. Users can choose one of them
Accuracy: 0.2% FS ± 1 word or 0.5% FS ± 1 word
Output: RS485 digital alarm signal, voltage+instrument alarm4~20mA
Resolution: 1, 0.1, 0.01, or 0.001 words
Display mode: LED digital display (decimal point position optional); Light column display; LED alarm indication
Alarm output mode: Low Low (L-L), Low (L), High (H), High High (H-H) four sets of relay normally open and normally closed contact outputs; Contact capacity: AC220V/3A; DC24V/6A (resistive load); The alarm point can be selected as any point at the level of the object
Control output mode: a set of relay normally open and normally closed contacts; Contact capacity AC220V/3A; DC24V/6A (resistive load); The material level can be controlled between the low (L) and high (H) positions, and the low and high positions can be selected at any point of the material level. By selecting the normally open/normally closed contacts of the control relay (K), automatic material entry/exit can be achieved, and the material level can be controlled between the set high/low positions.
