LCD Dual Loop Pressure Temperature Controller Liquid Level Monitor

Product Specification

Description LCD dual-loop pressure temperature controller liquid level monitor
 
Dual-loop series display controller is suitable for various temperature, pressure, liquid level, length and other measurement and control. The use of microprocessors for digital operation enables highly accurate linear correction of various nonlinear signals.
Dual-loop series light display controller integrates digital measurement display and analog measurement display. Digital LED display can accurately display and control real-time measurement values. At the same time, it adopts high-precision 40-line light column display to display real-time measurement values clearly and intuitively. Compare with other measurement parameters for convenience and intuition.
The dual-loop serial display controller opens the setting interface of the internal parameters of the instrument (including input type, calculation method, output parameters, communication parameters, etc.) to the user.
Double loop series display controller can switch input a variety of indexing numbers. With advanced non- jumper technology, you do not need to change jumpers or switches when changing the input division number. The entire instrument modification process does not need to be powered off. Only the instrument's index number and related parameters need to be set, and the input of the index number can be changed online.
Dual loop series display controller supports multi-machine communication, with a variety of standard serial two-way communication functions, you can choose a variety of communication methods (such as RS-232C, RS-485, RS-422, etc.), communication baud rate 300 ~9600bps meter internal parameters freely set. It can communicate with various devices with serial input and output (such as computers, programmable controllers, PLCs, etc.) to form an intelligent management system.
Equipped with a series of data collectors and all Chinese industrial control configuration software based on WINDOWS’9X platform, it is convenient to realize the networking management of multiple meters and upper computers.
