Oxygen gas transmitter OxyTrans LC-KF

electrochemicalconcentrationIP65

Description
The OxyTrans LC-KF is a loop-powered 2-wire oxygen transmitter for trace and percent-level measurement. Designed for industrial process monitoring, it provides continuous oxygen concentration output via a 4–20 mA signal suitable for integration into control systems.

Sensor
The unit uses a fuel-cell type electrochemical sensor selected for sensitivity to low oxygen concentrations and long operational life. The sensor assembly meets industrial requirements for repeatability and low maintenance.

Calibration
For trace oxygen ranges, calibrate the instrument with an appropriate calibration gas at the desired concentration within the measuring range. For percent-range measurements, calibration can be performed using ambient air.
