Product Description

The MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator (model 522P-050) is a differential pressure indicator with a maximum static pressure of 1,000 psig. It features an accuracy of ±5% of Full Scale, a Buna-N sensor, and an Acetal Plastic housing. The indicator uses three color-coded transition points: green from 0 psid to 20 psid, yellow from 20 psid to 30 psid, and red from 30 psid to 50 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, such as filtration, lubrication, and hydraulic circuits. The three-color display (green, yellow, red) provides a quick visual status of pressure conditions, helping operators identify when filter cleaning or system maintenance is needed.

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

The MIDWEST INSTRUMENT 522P-050 has a maximum static pressure of 1,000 psig, accuracy of ±5% of Full Scale, a Buna-N sensor, and an Acetal Plastic housing. Transition points are 0 psid to 20 psid (green), 20 psid to 30 psid (yellow), and 30 psid to 50 psid (red).

Where to buy the MIDWEST INSTRUMENT 522P-050 worldwide?

You can source the MIDWEST INSTRUMENT 522P-050 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?

Install the indicator in a clean, dry location within the system's pressure rating. Use appropriate thread sealant on connections and avoid overtightening the Acetal Plastic housing. After installation, verify the pointer moves through all three color zones during system operation to confirm correct function.
