Overview
The NOSHOK PT20-100psig-1-1-2-7-ST8 is a bourdon tube pressure gauge designed for industrial applications. It features a 100 psig measurement range with a 3-1/2 inch dial diameter. The device utilizes a stainless steel wetted materials construction, including a 316 stainless steel bourdon tube and diaphragm seal, ensuring compatibility with various media. It offers an accuracy class of 4% of full scale and operates within a temperature range of -40°F to 250°F for the process and -40°F to 185°F for ambient conditions. The unit is equipped with a 1/4 inch NPT lower connection.
Feature Summary
- Constructed with 316 stainless steel wetted parts for corrosion resistance and durability in demanding environments.
- Features a liquid-filled movement option to dampen vibration and pulsation, enhancing reading stability.
- Includes a blow-out back design to protect internal mechanisms from overpressure events.
- Provides clear readability through a high-contrast white dial with black markings.
Applications
- Hydraulic and pneumatic system monitoring
- Compressed air line pressure indication
- Industrial machinery lubrication systems
- Water treatment and pump control panels
Procurement Notes
Verify that the specific model number matches the required pressure range and connection size for your application. Confirm whether the liquid-filled variant is necessary for your environment to prevent needle oscillation. Ensure the process media is compatible with 316 stainless steel components. Check if additional certifications or special calibrations are required by your industry standards before finalizing the order.
Selection Notes
Select this gauge when a robust, general-purpose pressure indicator is needed for moderate pressure ranges up to 100 psi. Consider the liquid-filled version if the application involves significant vibration or rapid pressure fluctuations. Evaluate the need for specialized dial colors or custom scales if standard configurations do not meet visual identification requirements. Ensure the operating temperature remains within the specified limits to maintain accuracy.
Part Context
This component belongs to the NOSHOK PT series of bourdon tube pressure gauges, which are widely used in industrial settings for reliable pressure measurement. The PT series is known for its durable construction and compliance with industry standards. This specific model represents a standard configuration within the lineup, offering a balance of performance and cost-effectiveness for common industrial tasks.
Replacement Considerations
When replacing this unit, ensure the new gauge has the same pressure range, connection thread size, and dial diameter. Verify that the wetted material compatibility matches the existing system fluids. If the original was liquid-filled, the replacement should also be filled to maintain vibration damping characteristics. Check for any changes in accuracy class requirements.
