Overview
The NOSHOK PT20-300PSIG-1-1-8-18-ST8-CC is an industrial pressure transmitter from the PT20 series, designed for high-pressure applications. It features a fixed measurement range of 0 to 300 psi gauge. The device utilizes a 4 mA to 20 mA two-wire analog output signal. It incorporates a non-linearity specification of 0.5% of span, calculated using the best fit straight line method per IEC 61298-2 at reference conditions. The unit is equipped with a 1/4-18 UNF 2B high-pressure process connection interface.
Feature Summary
- Provides a standardized 4 mA to 20 mA two-wire analog output for integration into control systems.
- Ensures measurement accuracy through a 0.5% of span non-linearity tolerance based on best fit straight line methodology.
- Features a robust high-pressure process connection interface compatible with standard industrial fittings.
Applications
- Industrial process monitoring
- Hydraulic system pressure tracking
- High-pressure fluid control
Procurement Notes
Verify the specific model suffixes against official NOSHOK documentation to confirm exact process connection threads and electrical configurations. Ensure the required pressure range aligns with system operating parameters. Confirm compliance requirements such as RoHS status prior to ordering. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and technical datasheet versions.
Selection Notes
Select this component when a fixed-range pressure transmitter with a 4-20 mA output is required for high-pressure environments. The PT20 series offers a balance of accuracy and durability for industrial settings. Consider the 1/4-18 UNF 2B connection size during mechanical design. Evaluate the 0.5% non-linearity specification against application tolerance requirements. Ensure power supply compatibility with two-wire loop-powered devices.
Part Context
This part belongs to the NOSHOK PT20 series of industrial pressure sensors. The series is characterized by fixed-range transmitters designed for demanding industrial environments. These units typically feature stainless steel construction for corrosion resistance and reliability. The PT20 series supports various process connections and output signals to accommodate diverse system integration needs.
Replacement Considerations
Consult official NOSHOK substitution guides for direct replacements. Verify that alternative models match the 300 psi gauge range and 4-20 mA output. Ensure thread compatibility with the existing 1/4-18 UNF 2B interface. Check dimensional constraints for panel or pipe mounting.
