PT40-7500psig-1-2-2-3

Pressure Sensors Transducers Overview

The NOSHOK PT40-7500psig-1-2-2-3 is a high-pressure process diaphragm seal pressure transmitter designed for industrial applications requiring isolation from corrosive or viscous media. It features a 316L stainless steel wetted material construction with a 7500 psig full-scale range. The unit utilizes a 4-20 mA analog output signal and operates on a 10-30 VDC power supply. Key interface specifications include a 1/2-14 NPT process connection and a 1/4-18 NPT electrical connection. The device provides an accuracy of ±0.25% of span and includes an LCD display for local monitoring. It is engineered to withstand high static pressures while maintaining precise measurement stability in demanding environments.

Pressure Sensors Transducers Feature Summary

• Isolates sensitive instrumentation from aggressive, viscous, or crystallizing process media using a diaphragm seal system
• Provides accurate pressure measurement through a robust 316L stainless steel wetted path construction
• Features integrated local indication via an LCD display for immediate visual monitoring of process conditions

Pressure Sensors Transducers Applications

• Chemical processing systems handling corrosive fluids
• High-pressure steam generation and distribution networks
• Oil and gas extraction equipment requiring isolated sensing
• Pharmaceutical manufacturing processes with hygiene requirements

Pressure Sensors Transducers Procurement Notes

Verify that the specified 7500 psig range aligns with the maximum operating pressure of the target application to prevent over-ranging. Confirm that the 1/2-14 NPT process connection matches the existing piping flange or thread standards. Ensure the required output signal configuration corresponds to the control system input capabilities. Check environmental ratings against site temperature extremes. Review warranty terms regarding diaphragm material compatibility with specific chemical agents.

Pressure Sensors Transducers Selection Notes

Select this model when high-pressure isolation is critical to protect the sensor element from direct contact with hazardous media. The 316L stainless steel construction offers broad chemical resistance suitable for many industrial fluids. Consider the ±0.25% accuracy specification for applications requiring precise process control. Evaluate the need for local LCD indication versus remote-only monitoring. Ensure the power supply voltage range of 10-30 VDC is compatible with the available field wiring infrastructure.

Pressure Sensors Transducers Part Context

This transmitter belongs to the NOSHOK PT40 series, which focuses on high-performance pressure measurement solutions for severe service conditions. The series emphasizes durability and reliability in industries such as petrochemical, power generation, and water treatment. The PT40 line typically integrates advanced electronics with rugged mechanical designs to ensure long-term stability. This specific variant addresses the niche requirement for ultra-high pressure ranges up to 7500 psig while maintaining standard industrial communication protocols.

Pressure Sensors Transducers Replacement Considerations

When replacing older models, verify that the new unit's physical dimensions fit within the existing mounting space. Confirm that the electrical connection type remains compatible with current cable glands. Check if the replacement requires any adjustments to the zero and span calibration procedures. Ensure that the diaphragm seal fill fluid is compatible with the previous installation to avoid thermal expansion issues.
