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 three-color display (green, yellow, red) to indicate filter condition, flow status, or pressure drop across equipment. It is suitable for applications with static pressure up to 1,000 psig.

What are the specifications of the MIDWEST INSTRUMENT 522A-030-LE?

The MIDWEST INSTRUMENT 522A-030-LE has a maximum static pressure of 1,000 psig, accuracy of ±5% of Full Scale, a Buna-N sensor, and an aluminum housing. Its transition points are 0–13 psid (green), 13–20 psid (yellow), and 20–30 psid (red).

Where to buy the MIDWEST INSTRUMENT 522A-030-LE worldwide?

You can source the MIDWEST INSTRUMENT 522A-030-LE 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 right MIDWEST INSTRUMENT differential pressure indicator?

Select based on your system's maximum static pressure (this model handles 1,000 psig), required pressure range (0–30 psid), sensor material compatibility (Buna-N for oil/water), and desired visual indication. The three-color zones help quickly identify normal, caution, and alarm conditions.
