Data Center Solutions: Precision Monitoring for Uninterrupted Operations
DwyerOmega offers a comprehensive suite of measurement solutions specifically designed to address the critical challenges of modern data centers, focusing on environmental monitoring, cooling system safety, energy management, and equipment protection. These solutions are engineered to ensure the stable, efficient, and safe operation of data center facilities, minimizing downtime and reducing operational costs.
Key Monitoring Scenarios and Solutions
- Refrigerant Gas Detection: The Axiom series refrigerant gas detectors provide early warning of leaks with high resolution (0.01% or 100ppm), a 15-year calibration-free lifespan, IP68 protection, and anti-condensation features, ensuring the safety of cooling systems.
- Leak Detection: The Dwyer WD3 series leak detectors and F7 series liquid level switches prevent water damage by monitoring air conditioning drip pans, raised floors, and chiller units, providing both local audio-visual alarms and remote control capabilities.
- Flow Measurement: The IEF/IEFB series insertion electromagnetic flowmeters/BTU meters deliver accurate cooling water flow measurement (±1% accuracy) for pipes from 3" to 36", with support for BACnet/Modbus protocols for seamless integration into building management systems.
- Temperature & Humidity Measurement: A combination of sensors from ACI (A/TTM, A/RH series), Dwyer (TE, RHPX series), and Rotronic (HF series) ensures precise environmental control. These sensors offer high accuracy (±0.1%FS optional), NIST traceable calibration, and long-term stability (drift <1%rh), maintaining humidity within the optimal 40%-60%RH range to prevent static discharge and corrosion.
- Pressure Measurement: The ACI MLP2/DLP series and Dwyer MSX series pressure transmitters monitor room and duct differential pressure with high precision (±0.25%FS) and multiple output protocols, ensuring proper airflow and maintaining clean room conditions.
- Power Monitoring: The ACI MSCT series current sensors and KW series power meters provide real-time monitoring of electrical loads with ±0.4%FS accuracy, enabling early fault detection and reducing operational risks.
