GfG Instrumentation, 2210-030, Dynagard 25 with ZD 21 Transmitter for Detecting Oxygen (O2)
The comprehensive electronics allow for easy operation and maintenance and also increase operational safety and accuracy. In less than 2 seconds, the ZD 21 responds to an oxygen deficiency. The sensor has a platinum coating on the inside and outside of the ceramic cylinder. Oxygen is electrochemically reduced at the cathode. The voltage produced is proportional to the net difference in the partial pressures of oxygen in the reference gas versus the sampled gas. This extremely short response time allows the user the time to take measures to prevent considerable damage.
The Dynagard 25 Series accurately measures oxygen levels. The unit offers a local display, a horn / strobe, and a linear 4-20 mA output. The Dynagard 25 Series offers a safe and reliable gas warning system
Each alarm can be adjusted separately. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be set to over range / under range, latching / non-latching, or resettable / non-resettable
