Pressure and Flow Sensors for Cooling Applications in Data Centers

Our pressure and flow sensors are the optimal choice for cooling devices utilizing air and/or liquids in data centers, such as CRAC (Computer Room Air Conditioning), CDU (Coolant Distribution Unit), and In-Rack CDU systems. They ensure reliable and precise measurement data, facilitating optimal and efficient operation of cooling and filtration systems.

 

CRAC (Computer Room Air Conditioning)

  • Filter Monitoring
    Differential Pressure Switch 604
    Differential Pressure Switch monitors pressure difference before/after filter and ensures alert for maintenance if pollution level is too high.

  • Air Flow Control 
    Differential Pressure Transmitter 699 
    Differential pressure transmitter measures air flow (volume?) and thus enables to control the control of the fan speed.

 

In-Rack CDU

  • Pressure Measurement in Water Circuits
    Pressure Transmitter Type 528
    This pressure sensor monitors the system pressure within the cooling circuit to regulate optimal cooling performance, thus overseeing and enhancing the system's efficiency.

  • Flow Monitoring in Water Circuits 
    Flow Sensor Type 210
    The Vortex flow sensor is utilized to monitor the flow rate of cooling water or a water/glycol mixture. This monitoring enables the regulation of optimal cooling performance and ensures the system's efficiency.

 

CDU (Coolant Distribution Unit)

  • Pressure Measurement in Water Circuits 
    Pressure Transmitter Type 528 
    This pressure sensor monitors the system pressure within the cooling circuit to regulate optimal cooling performance, thereby overseeing and enhancing the efficiency of the system.

  • Water Filter Monitoring​​​​​​​ 
    Differential Pressure Transmitter Type 692
    The Differential Pressure Transmitter 692 monitors the pressure difference between two relevant measurement points, such as across the water filter, to manage service intervals.  

  • Flow Monitoring in Water Circuits
    Flow Sensor Type 210
    The Vortex flow sensor is utilized to monitor the flow rate of cooling water or water/glycol mixtures. This allows for the regulation of optimal cooling performance and ensures the efficiency of the system.
