Endress Hauser COM253 Universal Dissolved Oxygen Measurement Transmitter

Higher operational security: continuous process inspection system, customized alarm settings, calibration authenticity check

Reliable dissolved oxygen control: current input for flow rate monitoring and feedforward control with controller shutdown

Simple operation and maintenance: perform simple point-to-point calibration in air, oxygen saturated water or medium, and directly perform manual touch control

Reduce maintenance: trigger automatic cleaning function through alarm or limit switch (using Chemoclean)

Suitable for various application scenarios: multiple extension functions, such as P (ID) controllers, timers, etc., flexibly applied to various processes

Measurement principle:four-wire system

Product positioning:standard

Usage scenario:The Liquisys COM253 standard transmitter can be used in conjunction with dissolved oxygen measurement sensors COS41 and COS61. Improve operational safety through continuous rationality testing and process and sensor detection. Choose from numerous hardware and software modules (such as relays and bus communication) to meet the requirements of measurement tasks. It also allows for the upgrade of the transmitter at any time, and the simple menu and calibration make instrument setup and operation convenient and fast.

The Liquisys COM253 transmitter can be paired with Oxymax COS41 and Oxymax COS61 dissolved oxygen sensors for measurement in the environmental protection industry, such as:

O2 aeration tank control

O2 drinking water control and monitoring

Surface water monitoring

Process water treatment and monitoring

Optimization and control of growth conditions in O2 fish pond

Liquisys COM253 adopts the following communication protocols and interfaces:

0/4...20 mA

HART

PROFIBUS DP

PROFIBUS PA
