TDS210-C Conductivity Controller for EC, TDS, and ER Measurement
Introduction
The TDS210-C Conductivity Controller is an intelligent, ruggedized Industrial EC Controller and Online Chemical Analyzer engineered for continuous, high-accuracy liquid analysis. It provides reliable, multi-parameter measurement of Electrical Conductivity (EC), Total Dissolved Solids (TDS), Resistivity (ER), and solution temperature.
Unlike conventional process instrumentation, the TDS210-C is specifically designed and validated for deployment in process streams containing contaminants and other challenging media.
Precision and Integration Standards
The TDS210-C guarantees actionable control through standardized, reliable technology:
· Verified Accuracy: Provides consistent measurement with ±2%FS resolution.
· Control Outputs: Integrates seamlessly into industrial loops with AC250V, 3A Relay outputs for both high and low alarming or process actuation.
· Isolated Data: Features an isolated 4-20mA analog output and RS485 (MODBUS-RTU) digital communication for minimal electrical interference.
· Wide Range Capability: Supports multiple cell constants (from 0.01 to 10.0 electrodes) to cover ranges from pure water (0.02 µs/cm to highly conductive solutions (20 ms/cm).
· Power Standard: Operates on standard AC220V ±10% power supply (or optional DC24V).
