Endress+Hauser COM253-DX0005 | Liquisys DO Transmitter, 4-20mA HART, Wall Mount
Endress+Hauser COM253-DX0005 single-channel DO transmitter for COS41/COS61 sensors. 100-230V AC, 4-20mA HART output, IP65 wall-mount housing.
Product Overview
The Endress+Hauser COM253-DX0005 is a single-channel, wall-mount transmitter from the Liquisys COM253 series for dissolved oxygen (DO) measurement. Designed for water, wastewater, and aquaculture applications, it features a graphical LCD, supports both analog and Memosens digital DO sensors (like COS41/COS61), and provides a 4-20mA HART output for integration into process control systems.
Dual Sensor Support: Compatible with both traditional analog (e.g., COS41-2F) and advanced Memosens digital DO sensors (e.g., COS61), offering flexibility in sensor selection and future upgrades.
Process Diagnostics: Features continuous sensor and process monitoring with plausibility checks, providing early warnings for sensor failure or process deviations.
Easy Calibration: Simplified one-point calibration procedure (in air or saturated water) guided by the graphical display, reducing maintenance time.
Modular Platform: The COM253 base platform allows for optional expansion with relay modules or additional communication cards if future needs change.
Applications
Wastewater Aeration Control: Precise DO monitoring in activated sludge basins to optimize blower energy consumption.
Surface Water Monitoring: Environmental monitoring of dissolved oxygen in rivers, lakes, and reservoirs.
Aquaculture & Fish Farming: Maintaining optimal oxygen levels in fish ponds and hatchery tanks.
Drinking & Process Water: Quality control in potable water treatment and industrial process water systems.
