EC 22O Transmitter with Display

GfG Instrumentation, EC22O-730-D, EC 22O Transmitter with Sensor, Oxygen O2 MK 422-0 with Display, 4-20 mAFeatures:Measuring Principle Electrochemical (EC)Partial Pressure Sensor for Oxygen in Air Containing HeliumExpected Sensor Life 5 yearsProtection Class IP54If oxygen is to be monitored in applications with high helium concentration where other oxygen sensors show deviating results, the EC22 O transmitter is a reliable and economical solution. In combination with GfG's proven controllers, installation in new gas detection systems as well as retrofitting in existing systems is possible.The EC22 O detects oxygen by means of the electrochemical process (EC). The long-life partial pressure sensor measures the oxygen concentration accurately and in a measuring range from 0 to 35 vol.%, even in air containing helium. Automatic temperature compensation and linearization of the measurement signals ensure high measurement accuracy.Device protectionThe housing is protected against the ingress of dust and water (protection class: IP54).Communication and serviceSignals are transmitted according to the analogue industrial standard. The transmitter indicates operating states via two status LEDs.
