Dynagard 25 Series O2 - Single point fixed oxygen monitoring system.
Simple and effective
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.
Alarm points
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.
Alarm relays
The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.
ZD21 zirconia sensor
The comprehensive electronics allow for easy operation and maintenance and also increase operational safety and accuracy. In less than 2 seconds, the ZD21 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.
