Ask A Question

Description & Features

Crafted from durable 304 stainless steel this 2.5" liquid-filled pressure gauge is designed for precision and reliability. The unit offers a pressure measurement range of 0-1 500 PSI or 0-100 Bar making it suitable for various industrial applications.

The bottom connection interface features a 1/4 NPT male brass connection with a 0.013" throttle plug ensuring secure and accurate readings. The gauge includes a polycarbonate window and a liquid-filled interior that enhances shock resistance and vibration dampening capabilities.

The ENGINEERED Specialty Products bottom connect pressure gauge 649102 maintains accuracy ratings of 3-2-3% of span. It is built to handle normal operating pressures confined to 25%-75% of the gauge's full scale with a maximum operating gauge pressure not exceeding 50% if pulsation is present.

Specified dimensions are A=2.48 B=1.21 C=2.71 and D=0.46 ensuring compatibility with various mounting setups. This gauge is ideal for critical measurement tasks where precision and durability are paramount.

got a line that bounces around some, is this gauge gonna hold steady or is it touchy?

Liquid fill helps a lot with that kind of service since it dampens vibration and shock so the needle is easier to read. It also has a 0.013 inch throttle plug in the 1/4 NPT bottom brass connection, which further smooths out pressure pulses for more stable readings.

Wondering if this gauge can handle the pressure if it's always running near the top end of its range?
Answer by: Customer Support on Jul 1, 2025, 5:57 PM
The recommendation is to keep normal operating pressure between 25% and 75% of the full scale. If you've got pulsation, you shouldn't exceed 50% of the full scale to keep the gauge working right.
