Features:
- Measuring principle: zirconium dioxide (ZD) for oxygen
- Expected sensor lifetime 4-5 years
- Signal transmission 0.2-1 mA / 4-20 mA / RS-485
- Protection class IP54
- Approvals / Certifications SIL 2/3 (hardware)
If oxygen is to be monitored selectively and over a long period of time, the ZD22 transmitter is a reliable and economical solution. The ZD22 transmits measured values and status displays Analogue. In combination with GfG's proven controllers, installation in gas detection systems as well as retrofitting in existing systems is possible.
The ZD22 detects oxygen using a zirconium dioxide (ZD) sensor that is insensitive to ambient conditions and sensor poisons.
Functional safety and device protection
The hardware of the ZD22 complies with the European Functional Safety Standard DIN EN 61508-2: 2011 (SIL). The housing is protected against the ingress of dust and water (protection class: IP54).
Communication and service
Signals are transmitted according to the Analogue industrial standard. The transmitter indicates operating states via two status LEDs.
