Frequently Asked Questions

What is the MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator used for?

The MIDWEST INSTRUMENT 3-Color Differential Pressure Indicator is used to monitor and display differential pressure in industrial fluid systems. Its three-color visual indication (green, yellow, red) allows operators to quickly assess filter condition, flow status, or system blockages without additional instrumentation.

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

The MIDWEST INSTRUMENT 522A-025-LA 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 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 522A-025-LA worldwide?

You can source the MIDWEST INSTRUMENT 522A-025-LA worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

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

Install the MIDWEST INSTRUMENT indicator by mounting it in-line with the process piping using appropriate fittings. Ensure the static pressure does not exceed 1,000 psig. Follow standard practices for differential pressure devices: verify port connections, avoid overtightening, and check for leaks before commissioning.
