Product Description

The MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator (MPN 522A-005-LE) is a differential pressure indicator with switch, featuring a Buna-N sensor and aluminum housing. It provides ±5% of full scale accuracy and transitions through three color zones: green from 0 psid to 3 psid, yellow from 3 psid to 4 psid, and red from 4 psid to 5 psid, with a maximum static pressure of 1,000 psig.

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 alert through three color zones. It is commonly applied in filtration, pump, and hydraulic systems where operators need to quickly identify when filter cleaning or replacement is needed based on pressure drop thresholds.

What are the specifications of the MIDWEST INSTRUMENT 522A-005-LE?

The MIDWEST INSTRUMENT 522A-005-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 0–3 psid (green), 3–4 psid (yellow), and 4–5 psid (red).
