Yokogawa FLXA202 2-Wire Dual Channel Transmitter Analyzer for pH/ORP, Conductivity & DO Measurements with 24VDC Power
The FLEXA™ series analyzers are modular-designed instruments used for continuous online measurements in industrial installations. The FLXA202 model offers single or dual sensor measurement capability, providing exceptional flexibility as a 2-wire analyzer.
Through installation of up to two sensors, the FLXA202 enables interruption-free measurement during maintenance. For dual sensor operation, modules must measure the same parameter (pH/ORP and pH/ORP, SC and SC, or DO and DO). This configuration provides calculated data from both measuring parameters and allows programming as a redundant system.
One analyzer accepts four measurement types: pH/ORP, Contacting Conductivity (SC), Inductive Conductivity (ISC), and Dissolved Oxygen (DO). Sensors feature self-diagnostics capabilities with additional functions including:
The FLEXA™ series provides improved operability with intuitive touchscreen operation, featuring a clear display with 12 language options. Quick setup menu enables immediate measurement while displaying sensor status and estimated maintenance time for enhanced efficiency. The interactive screen is housed in a robust aluminum die-cast housing.
Featuring a modular design with replaceable sensor modules, the analyzer enables construction of various systems. Users can opt for display-free operation and select case material (plastic or stainless steel).
