Endress+Hauser dissolved oxygen transmitter Liquisys COM253-WX8405

PRODUCT DESCRIPTION

Endress+Hauser COM253-WX8626 dissolved oxygen transmitter, E+H Liquisys COM253 Dissolved oxygen field transmitter. Compact field device for water, wastewater, utilities and fish farming. 4-wire transmitter with graphic display.

Liquisys COM253 is a standard transmitter for use with COS41 and COS61 oxygen sensors. It improves your operational safety thanks to continuous plausibility, process and sensor checks. Select from numerous hardware and software modules, such as relays or fieldbus communication, to adapt it exactly to your measuring task. This modularity also allows you to upgrade the transmitter at any time. A simple menu and calibration make configuration and operation fast and easy.

Endress+Hauser Liquisys COM253 Benefits:

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, direct access for manual contact control.

Reduced maintenance: Automatic cleaning function (with Chemoclean) triggered by alarm or limit switch.

Fit for every application: Numerous extensions, e.g. P(ID) controller, timer, etc., allow for flexible adaption to all processes.
