Data Center Coolant Pressure Sensor DCPQ

For MQD installation in liquid cooling circuits

The Data Center Coolant Pressure Sensor for Quick Connectors (DCPQ) is designed for integration into the liquid cooling circuit of data center racks and blades (coolant inlet/outlet, rack and blade level) and monitors coolant pressure to assess cooling performance and protect IT equipment.

The high-accuracy stainless steel sensor element is hermetically welded to a stainless steel pressure port, providing high media resistance and long-term stability.

An MQD-compatible (Multi Quick Disconnect) pressure port enables simple installation and dry connect/disconnect within the cooling circuit.
