Product Description

The MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator (MPN 522S-015-LE) is a differential pressure indicator with switch, featuring a 1,000 psig maximum static pressure. It offers ±5% of Full Scale accuracy, with a Buna-N sensor and 316 Stainless Steel housing. The indicator uses three color-coded transition points: Green from 0 psid to 7.5 psid, Yellow from 7.5 psid to 11 psid, and Red from 11 psid to 15 psid.

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 via three color zones (green, yellow, red) that correspond to pressure ranges from 0 psid to 15 psid. It is suitable for applications requiring a maximum static pressure of 1,000 psig, such as filtration or flow monitoring.

What are the specifications of the MIDWEST INSTRUMENT 522S-015-LE?

The MIDWEST INSTRUMENT 522S-015-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. Its transition points are 0 psid to 7.5 psid (green), 7.5 psid to 11 psid (yellow), and 11 psid to 15 psid (red).

Where to buy the MIDWEST INSTRUMENT 522S-015-LE worldwide?

You can source the MIDWEST INSTRUMENT 522S-015-LE 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.

How to install the MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator?
