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 status via three color zones. It is commonly applied in filtration, lubrication, and hydraulic systems where operators need quick, at-a-glance awareness of pressure conditions to schedule maintenance or detect blockages.

What are the specifications of the MIDWEST INSTRUMENT 522S-005?

The MIDWEST INSTRUMENT 522S-005 has a maximum static pressure of 1,000 psig, accuracy of ±5% of Full Scale, a Buna-N sensor, and a stainless steel housing. Its transition points are: green from 0 psid to 3 psid, yellow from 3 psid to 4 psid, and red from 4 psid to 5 psid.

Where to buy the MIDWEST INSTRUMENT 522S-005 worldwide?

You can source the MIDWEST INSTRUMENT 522S-005 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; we supply this differential pressure indicator to procurement teams and plant engineers internationally.

How to select the right differential pressure indicator for my system?

Select based on your system's maximum static pressure, required accuracy, and desired visual indication range. For the MIDWEST INSTRUMENT 522S-005, ensure your operating pressure stays below 1,000 psig and that the 0–5 psid transition zones match your monitoring needs. Verify compatibility of the Buna-N sensor with your fluid type.
