Trafag's NSL 8257 Low Pressure Transmitter
Trafag, a manufacturer of high-accuracy measurement devices, released the NSL 8257 Low Pressure Transmitter, engineered to deliver unparalleled performance in shipbuilding, large engine systems, and a broad range of general manufacturing environments.
With cutting-edge sensor design and robust construction, the NSL 8257 sets a new standard for low-pressure measurement across harsh and dynamic applications.
The NSL 8257 features thin-film-on-steel sensor technology, enabling highly accurate readings down to 0.2 bar (3 psi) with excellent long-term stability. This makes it an ideal solution for systems requiring sensitivity at very low pressures, where traditional transmitters often fall short, offering high performance-to-cost technology in demanding applications. Its ability to measure either relative or absolute pressure enhances application flexibility, while the compact form factor allows seamless integration into space-constrained installations.
Designed for reliability in extreme conditions, the transmitter boasts a welded stainless steel sensor system free of additional seals, ensuring superior media compatibility and leak resistance. Withstanding pressure spikes up to 125 times the nominal value, the NSL 8257 delivers consistent performance under critical conditions. It also operates within a wide temperature range of -40°C to +125°C and maintains precision with fast response times as low as 1 millisecond.
For demanding environments such as shipbuilding and engine rooms, the NSL 8257 meets DNV-GL approval standards and offers IP67 protection, making it suitable for both wet and dusty installations. Its resistance to mechanical stress—vibration up to 25 g and shock up to 100 g—ensures reliable function in high-vibration settings commonly encountered when working with engines or mobile machinery.
Offering multiple output signal options and a wide selection of electrical connectors and pressure connections, the NSL 8257 adapts effortlessly to existing systems and diverse operational requirements. Options like MIL-C are military-grade and considered top-of-the-line in durable connectors. Its high accuracy of 0.15% or 0.3% full scale surpasses the industry average accuracy for thin-film-on-steel designs, emphasizing Trafag’s commitment to innovation.
With the NSL 8257 low pressure transmitter, Trafag continues to establish its product portfolio of innovative solutions that blend precision engineering with rugged durability, reinforcing its position as a trusted partner in critical industrial measurement.
