Endress Hauser COM253-DX0005 Dissolved Oxygen Transmitter with HART Profibus

The Liquisys COM253-DX0005 is a dissolved oxygen transmitter designed for precise oxygen measurement in various industrial and environmental applications. This 4-wire transmitter features a graphic display and comes in a durable PC/ABS housing.

The Liquisys COM253 is a standard transmitter for use with COS41 and COS61 oxygen sensors, offering enhanced operational safety through continuous plausibility, process and sensor checks. Its modular design allows for numerous hardware and software configurations to adapt to specific measuring tasks.

Common applications include:

• O2 control in the aeration basin
• O2 control and monitoring of drinking water
• Surface water monitoring
• Process water treatment and monitoring
• O2 control in fish farming for optimum growth conditions

• More operational safety: Continuous process check system, customized alarm configuration, calibration plausibility check
• Reliable oxygen control: Current input for flow rate monitoring with controller shut off or for feedforward control
• Easy to operate and service: Simple single-point calibration in air, air-saturated water or in the medium
• Reduced maintenance: Automatic cleaning function (with Chemoclean) triggered by alarm or limit switch
• Flexible configuration: Numerous extensions allow for adaptation to all processes

• 0/4...20 mA
