Atmospheric oxygen sensors, closed sensor type with pressure connectionFor low oxygen concentrations, with pressure connection, suitable for GMH 569xGENERAL:For devices with external pressure port (GMH 5695/3695) this housing is optimal. Especially for systems with high or low pressure or with existing back pressure by flow.APPLICATION:It can be screwed airtight (Attention: Observe permissible operating pressure!). The device-pressure port is connected to the sensor pressure port. The device measures and compensates for the actual pressure at the sensor.SPECIFICATIONS:Sensor element: 
GOEL 381
Oxygen-partial pressure probe, mounted in external sensor housing replaceable (temperature sensor mounted in housing)
