Danfoss 003N-0078 Sensing Element

The Danfoss 003N-0078 sensing element is a critical replacement component designed for Danfoss AVTA thermostatic valves. Engineered for temperature-actuated cooling control, this element utilizes a remote sensor with a 2-meter capillary tube to monitor and regulate medium temperatures in demanding industrial environments. The universal charge within the sensor responds to temperature fluctuations by adjusting the valve orifice, ensuring precise flow modulation to maintain setpoint stability. Built for compatibility with the AVTA self-acting cooling water valve series, this sensing element is essential for systems requiring thermal regulation without external power. The brass sensor construction provides excellent thermal conductivity and corrosion resistance, while the G 1/2 connection ensures a secure fit during installation. Whether servicing a water-cooled condenser or a hydraulic oil cooling circuit, the 003N-0078 provides the mechanical reliability needed for proportional control in closed-loop cooling systems.

• Universal Temperature Charge: Optimized for a wide range of cooling applications, ensuring consistent bulb pressure across the entire operating range.
• Direct-Acting Control: Operates independently of pressure fluctuations, providing stable modulation for AVTA series valves.
• Durable Capillary Design: The 2-meter (approx. 6.6 ft) reinforced capillary allows for flexible sensor placement even in tight mechanical footprints.
• Armored Protection: Designed to withstand the vibration and thermal cycling common in industrial HVACR and process cooling environments.

• How do I confirm compatibility with my existing AVTA valve? This sensing element is specifically designed for the AVTA series. Ensure your valve body uses the standard threaded mounting interface for 003N series elements.
• What is the temperature range for the 003N-0078? This element is typically utilized in the 10°C to 80°C (50°F to 176°F) range, though specific control limits are determined by the valve body adjustment.
• Does this element require a specific sensor orientation? The sensor should be installed in a position where the media flows across the entire bulb surface to ensure accurate thermal response.
