Instrument Introduction
Shanghai Xuantian SJT-6000A typeOnline alkaline concentration analyzerIt is a monitoring device for real-time monitoring and control of alkaline solution concentration in industrial production processes, widely used in various industries such as chemical, chlor alkali, papermaking, textile, water treatment, etc. It measures the physical or chemical properties of the solution (such as conductivity, refractive index, density, etc.), combines temperature compensation algorithms and preset calibration models, quickly converts the signal into concentration values, and outputs them to the control system for automated control.
working principle
The core components of the instrument are the display and electrodes, which achieve accurate measurement by detecting the linear relationship between the conductivity and concentration of the solution. The built-in temperature sensor automatically compensates for the influence of environmental temperature on the results, and transmits them to the display through a high impedance circuit. After amplification and conversion, the corresponding concentration value is output.
Technical Features
Integrated temperature measurement electrode, single electrode can complete measurement;
Online alkaline concentration analyzerBuilt in automatic temperature compensation, real-time correction of measured values, eliminating temperature deviation;
Low cost, fast response time (T90<60 seconds), no need for sample pretreatment, suitable for continuous online monitoring;
Two sets of relay outputs, capable of independently and freely selecting high and low position control;
It has a current output of 4-20mA and the communication interface can be selected as RS-485, making it easy to connect to PLC/DCS control systems.
