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, such as hydraulic or filtration applications. The three-color display provides a quick visual reference: green for normal range (0–20 psid), yellow for caution (20–30 psid), and red for alarm (30–50 psid). It is suitable for systems with static pressure up to 1,000 psig.

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

The MIDWEST INSTRUMENT 522S-050 has a maximum static pressure of 1,000 psig and an accuracy of ±5% of Full Scale. It features a stainless steel housing and a Buna-N sensor. The transition points are 0–20 psid (green), 20–30 psid (yellow), and 30–50 psid (red). The manufacturer part number is 522S-050.
