Features:
- Measuring principle Electrochemical (EC)
- Partial pressure sensor for oxygen in air containing helium
- Expected sensor life 5 years
- 2.2-inch color display, built-in touch-button interface, buzzer
- Protection class IP54
If oxygen is to be monitored in applications with high helium concentration where other oxygen sensors show deviating results, the EC22 O transmitter with display is a reliable and economical solution. In addition, there is a local indication on the display and, in the event of an alarm, a local alarm via buzzer. 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 transmitter with display detects oxygen by means of the electrochemical process (EC). The current measured value can be read at any time on the 2.2-inch display, which lights up red in the event of an alarm. The long-life partial pressure sensor measures the oxygen concentration accurately and in a measuring range of 0 to 35% by volume, even in air containing helium. Automatic temperature compensation and linearization of the measurement signals ensure high measurement accuracy.
Device protection
The housing is protected against the ingress of dust and water (protection class: IP54).
Communication and service
Signal transmission is carried out according to the analog industry standard. Operating states are indicated by the transmitter via two status LEDs. Service and settings are performed intuitively on site using three keys directly on the device (one-man adjustment).
