Frequently Asked Questions

What is the MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator used for?

This indicator is used to monitor differential pressure in industrial fluid systems, providing a visual 3-color display (Green, Yellow, Red) to indicate filter condition, flow status, or pressure drop across equipment. It is suitable for applications requiring up to 1,000 psig static pressure.

What are the specifications of the MIDWEST INSTRUMENT 522S-030-LA?

The MIDWEST INSTRUMENT 522S-030-LA has a maximum static pressure of 1,000 psig, accuracy of ±5% of Full Scale, a Buna-N sensor, and a 316 Stainless Steel housing. Transition points are 0 psid to 13 psid (Green), 13 psid to 20 psid (Yellow), and 20 psid to 30 psid (Red).

Where to buy the MIDWEST INSTRUMENT 522S-030-LA worldwide?

You can source the MIDWEST INSTRUMENT 522S-030-LA through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

How to select the correct MIDWEST INSTRUMENT differential pressure indicator?

Select based on your system's maximum static pressure (this model handles 1,000 psig), required transition points (0–30 psid range), sensor material compatibility (Buna-N for many fluids), and housing material (316 Stainless Steel for corrosion resistance). Verify accuracy needs against the ±5% of Full Scale specification.
