Frequently Asked Questions

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

This indicator provides visual monitoring of differential pressure across filters, pumps, or process lines. Its three-color scale (green, yellow, red) gives operators an immediate status check, helping prevent system damage in industrial fluid or gas applications.

What are the specifications of the MIDWEST INSTRUMENT 522S-050-LE?

The MIDWEST INSTRUMENT 522S-050-LE 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 20 psid (Green), 20 psid to 30 psid (Yellow), and 30 psid to 50 psid (Red).

Where to buy the MIDWEST INSTRUMENT 522S-050-LE worldwide?

3G Electric supplies the MIDWEST INSTRUMENT 522S-050-LE to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this differential pressure indicator.

How to select a differential pressure indicator for a filter monitoring application?

Choose a model with a maximum static pressure rating above your system's operating pressure, like the 1,000 psig on the MIDWEST INSTRUMENT 522S-050-LE. Verify sensor material compatibility with your fluid (Buna-N works with many oils and fuels) and select transition points that match your acceptable pressure drop range.
