SPAN

SPAN LFS-210 dial pressure gauges are available in pressure ranges from 0-30 psi up to 0-7,500 psi, with some models offering compound pressure and vacuum measurement (0-30 psi and 0-30 inHg). The specific range depends on the model number, which includes the pressure rating. For example, LFS-210-300-G-KEMX covers 0-300 psi, while LFS-210-7500-G-KEMX covers 0-7,500 psi. All models have a 2 1/2 inch dial and ±1.00% accuracy. When selecting a gauge, ensure the pressure range matches the system's operating pressure, typically choosing a range where normal operation falls within the middle half of the scale for best accuracy.

The freeze- and clog-resistant internal seal in SPAN LFS-210 gauges is filled with instrument oil, which helps prevent the gauge mechanism from freezing or becoming clogged by process media. This is particularly useful in applications where the fluid may solidify or contain particles that could obstruct the pressure port. The seal design isolates the gauge internals from the process fluid, allowing reliable pressure measurement even in challenging conditions. The wetted parts are brass and copper, and the seal material is Buna-N, compatible with many hydraulic and pneumatic fluids. This feature reduces maintenance needs and extends gauge life in environments prone to freezing or clogging.

Yes, SPAN LFS-210 pressure gauges feature a glycerin-filled case that dampens vibration, protecting the movement and ensuring stable readings. This makes them suitable for use on machinery, hydraulic power units, and other equipment where vibration is present. The glycerin fill also lubricates internal components and helps prevent wear. For applications with significant vibration, the liquid-filled case is a common solution to maintain accuracy and extend gauge life. The gauges also have an IP65 rating on some models, providing additional protection against dust and water ingress, further enhancing durability in harsh environments.

SPAN LFS-210 dial pressure gauges have wetted parts made of brass and copper. The internal seal is Buna-N (nitrile rubber), and the seal fill liquid is instrument oil. The case is filled with glycerin for vibration dampening. These materials are compatible with a wide range of fluids, including hydraulic oils, water, and air, but should be checked against the specific process media for chemical compatibility. Brass and copper offer good corrosion resistance in many industrial environments, though they may not be suitable for aggressive chemicals or certain gases. Always verify compatibility before installation to ensure reliable performance and safety.

SPAN LFS-210 dial pressure gauges have an accuracy of ±1.00% of full scale. This means that for a gauge with a 0-300 psi range, the reading error is within ±3 psi. This level of accuracy is typical for industrial pressure gauges and is suitable for most process and hydraulic applications where precise measurement is required but not to the level of test gauges. The accuracy is maintained across the entire range, and the glycerin fill helps stabilize the reading under vibration. For critical applications, consider the specific requirements and whether a higher accuracy gauge is needed.

Yes, SPAN offers a compound gauge model (SKU 5NMX2) that measures both positive pressure from 0 to 30 psi and vacuum from 0 to 30 inHg. This dual-scale gauge is useful in applications where the system may experience both pressure and vacuum conditions, such as in certain pneumatic or process systems. The gauge has a 2 1/2 inch dial, ±1.00% accuracy, and features the same freeze- and clog-resistant internal seal and glycerin-filled case as other LFS-210 models. It is identified by its model number and is available through 3G Electric. When selecting a compound gauge, ensure the pressure and vacuum ranges match your application requirements.
