Overview
The NOSHOK PT30-100psia-1-1-2-46-ST8 is a precision absolute pressure gauge designed for measuring pressures relative to a perfect vacuum. This model features a 100 psia measurement range and utilizes an internal Bourdon tube mechanism housed within a sealed case. The instrument incorporates liquid filling to dampen pointer oscillation and protect internal components from vibration and shock, ensuring stable readings in dynamic environments. It is constructed with corrosion-resistant materials suitable for various industrial gas applications.
Feature Summary
- Measures pressure relative to a perfect vacuum using an internal Bourdon tube mechanism
- Liquid-filled construction provides damping against vibration and shock
- Sealed case design protects internal components from environmental factors
Applications
- Aerospace systems requiring absolute pressure monitoring
- Vacuum process control and monitoring
- Barometric pressure measurement in weather stations
- Altitude simulation testing equipment
Procurement Notes
Verify the specific connection type and dial size configuration required for your installation before ordering. Confirm that the process media is compatible with the wetted materials of the gauge. Ensure the operating environment does not exceed the specified temperature limits for the liquid fill. Check for any special calibration requirements or certifications needed for your industry compliance.
Selection Notes
Select this absolute pressure gauge when measurements must be referenced to zero pressure rather than atmospheric pressure. Consider the liquid-filled option if the application involves significant mechanical vibration or pulsating flow. Evaluate the material compatibility of the sensor element with the process fluid to prevent corrosion. Compare the required accuracy class against the available options in the PT30 series.
Part Context
This component belongs to the NOSHOK PT30 series of absolute pressure gauges. The series is known for providing reliable absolute pressure measurement solutions across various industrial sectors. The PT30 line typically offers multiple range options and connection configurations to suit diverse system requirements. NOSHOK manufactures these instruments with a focus on durability and long-term stability.
Replacement Considerations
When replacing existing absolute pressure gauges, ensure the new unit matches the original port thread size and orientation. Verify that the replacement gauge has a compatible pressure range and accuracy level. Check if the mounting style and dial visibility requirements are met by the substitute part.
