Product Description

The MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator (MPN 522S-025-LA) is a differential pressure indicator with switch, featuring a 1,000 psig maximum static pressure and ±5% of Full Scale accuracy. It uses a Buna-N sensor and 316 Stainless Steel housing, with color-coded transition points: 0 psid to 11 psid (Green), 11 psid to 18.5 psid (Yellow), and 18.5 psid to 25 psid (Red).

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-coded zones (Green, Yellow, Red) that correspond to pressure ranges from 0 psid to 25 psid. It is commonly applied in filtration, pump, and pipeline monitoring where quick status recognition is needed.

What are the specifications of the MIDWEST INSTRUMENT 522S-025-LA?

The MIDWEST INSTRUMENT 522S-025-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. Its transition points are 0 psid to 11 psid (Green), 11 psid to 18.5 psid (Yellow), and 18.5 psid to 25 psid (Red).

Where to buy the MIDWEST INSTRUMENT 522S-025-LA worldwide?

You can source the MIDWEST INSTRUMENT 522S-025-LA through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
