Specification:
|
|
OCS1 |
|
1. Oxygen Concentrator sourced O2 mixture. (J1.4 open) 2. Medical/Hospital Ventilator Oxygen/Air mixer sourced O2 mixture. (J1.4 Set to GND) In circuit configurable to measure the Oxygen content in one of these gasses.
Powered by 8V to 35V / 7mA DC Power Supply, OCS1 provides UART & 0-5V O2 concentration & Flow Rate outputs. Thermal characteristics allow any Oxygen concentration measurement. No Flow Alarm output can serve to detect condition of No Flow.
