DPM72 O2C - Oxygen Controller

Oxygen Controller DPM72 O2C oxygen injection controller has a relay output


The DPM72 O2C oxygen injection controller has a relay output that is used to control a solenoid valve to maintain a constant partial pressure of oxygen in a decompression chamber or any enclosed compartment.

This unit uses a high stability electro-chemical sensor with built in temperature compensation to sense oxygen partial pressure in the compartment and a programmable display with time proportioning control software to operate the valve that controls the concentration of oxygen.

If the Oxygen concentration sensed by the oxygen sensor is below the control set point value, the controller will operate the solenoid valve for a user defined time period in the range 0 to 255 seconds. After the injection period the solenoid valve will close for a further user defined time period in the range 0 to 255 seconds, to allow for mixing. If the Oxygen level is still below the control set point the cycle repeats until the required Oxygen is reached.
