FLXA21 2-Wire Liquid Analyzer

Product catalog summary

Overview: The FLXA21 is a modular 2-wire liquid analyzer designed for measuring various liquid properties such as pH/ORP, contacting conductivity, inductive conductivity, and dissolved oxygen. It supports up to two sensors of the same type, enhancing reliability and reducing installation costs.

Key Features:

Touch Screen: The analyzer features an interactive touch screen that simplifies operation and reduces errors. It provides error codes and corrective actions, eliminating the need for constant reference to the manual.
Sensor Compatibility: Compatible with a wide range of sensors, including pH/ORP, contacting conductivity, inductive conductivity, and dissolved oxygen sensors.
Modular Design: The modular design allows for easy system configuration and scalability. System changes can be made by replacing or adding modules.
Advanced Functions: Includes sensor self-diagnosis, maintenance time estimation, and digital communication options (HART, FOUNDATION Fieldbus, PROFIBUS PA) for reduced maintenance costs.

Specifications:

Housing: Plastic with polycarbonate window, IP66 protection.
Dimensions: 144 (W) x 144 (H) x 151 (D) mm, weight approx. 1 kg.
Display: Black/white LCD with touch screen, 213 x 160 pixels.
Mounting Options: Pipe, wall, or panel mounting.
Environmental Conditions: Operates in temperatures from -20 to 55°C, storage from -30 to 70°C, and humidity from 10 to 90% RH.
Power Supply: Nominal 24 V DC loop powered system.
Regulatory Compliance: Meets UL, CSA, and EMC standards, with approvals for hazardous locations (ATEX, IECEx, FM, CSA, NEPSI).
Output Signal: One isolated output of 4 to 20 mA DC, 2-wire system.

Applications: Suitable for industrial applications requiring reliable and flexible liquid analysis with reduced maintenance and installation costs.
