Product details
Danfoss NSK Pressure Transmitter | 0 to 50 bar | Ratiometric Output
Product Description:
The Danfoss NSK (061H5154) is engineered to meet the demands of modern, high-pressure refrigerants like R410A. With a robust measuring range of 0 to 50 bar, this transmitter is the primary choice for monitoring discharge pressures in large VRF systems and commercial chillers across the UAE. Utilizing advanced ratiometric technology, the 061H5154 provides an output signal that scales precisely with the supply voltage, ensuring accurate data even in unstable electrical environments. Its hermetically sealed, stainless steel-compatible design is built to withstand extreme vibration and the intense heat of Dubai, making it an essential component for ensuring system safety and efficiency in high-performance cooling plants.
Key Features & Benefits:
- Extreme Pressure Capability: Rated up to 50 bar, making it ideal for the high-pressure side of modern HVAC/R systems in the UAE.
- Space-Efficient OEM Design: Its small size allows for direct mounting on pipework in congested equipment housing.
- Ratiometric Signal Integrity: Offers stable 0.5 – 4.5V output, providing high-resolution data for electronic expansion valve (EEV) controllers.
- Exceptional Environmental Resistance: Designed to operate reliably in the high humidity and high ambient temperatures of the Middle East.
- Vibration-Proof Construction: Built to handle the mechanical stresses of mounting directly on or near high-speed compressors.

FAQs:
- Q: Is this 50 bar version necessary for standard R134a systems in Dubai?
- A: While it will work, it is usually overkill for R134a. This model is specifically targeted at high-pressure refrigerants like R410A or R32.
- Q: Does it come with a flare nut?
- A: Most NSK models feature a female flare connection that threads directly onto a 1/4″ male flare service port common in UAE units.
- Q: Can this be used for oil pressure monitoring?
- A: Yes, the internal materials are compatible with standard refrigeration oils used in Dubai’s industrial compressors.
