Siemens Building Technology 544-578 Sensor 320734-701 This unit provides critical voltage

This unit provides critical voltage monitoring and protection for 3-phase HVAC systems by detecting and responding to electrical anomalies like phase loss

This stem assembly is primarily designed for Nor East Controls Series 8100 and V5011 globe valves

This part is a direct replacement for the superseded SWT02522 and is compatible with a wide range of Trane and American Standard equipment

Steam applications require specialized high-temperature graphite or metal-seated valves

Siemens Building Technology 544-578 Sensor 320734-701 This unit provides critical voltageThe Siemens 544 578 Outdoor Temperature Sensor is a critical component for building automation systems requiring precise ambient air monitoring. This 1k Ohm Platinum RTD (Resistance Temperature Detector) utilizes a 375a output signal to deliver high accuracy linearity across a wide operating range of 40 to 150 degrees Fahrenheit ( 40 to 65 Celsius). Engineered for durability in harsh environments, its NEMA 4 weatherproof housing protects the sensing
