PT20-30PSIG-1-2-2-25

Overview

The NOSHOK PT20-30PSIG-1-2-2-25 is an industrial pressure transmitter designed for gauge pressure measurement within a range of 0 to 30 psi. It utilizes a 4-wire configuration and provides a 4 mA to 20 mA analog output signal. The unit features a 1/4-18 UNF high-pressure process connection and is housed in a DIN form A enclosure with a 1/2 NPT female conduit connection. This model is part of the PT20 series, engineered for robust performance in demanding industrial environments requiring reliable pressure monitoring.

Feature Summary

• Provides a standard 4 mA to 20 mA current loop output for integration into control systems
• Features a 1/4-18 UNF high-pressure threaded process connection for secure installation
• Constructed with a DIN form A housing and 1/2 NPT female conduit entry
• Designed for gauge pressure applications with a fixed measurement range

Applications

• Industrial process control systems
• Hydraulic and pneumatic machinery monitoring
• Fluid power system pressure tracking
• Manufacturing equipment instrumentation

Procurement Notes

Verify that the required process connection matches the 1/4-18 UNF specification and confirm the 1/2 NPT conduit size aligns with existing panel or cabinet entries. Ensure the 4-wire wiring scheme is compatible with the receiving PLC or data acquisition hardware. Confirm the gauge pressure range of 0 to 30 psi meets the operational requirements of the target application before finalizing the order.

Selection Notes

Select this model when a fixed 0 to 30 psi gauge range is sufficient for the application. The 4-wire design offers distinct power and signal lines, which may be preferred over 2-wire loops in specific noise-sensitive or long-distance scenarios. The DIN form A housing allows for standard panel mounting. Verify that the 1/4-18 UNF thread is available on the process interface to avoid custom adapters.

Part Context

This component belongs to the NOSHOK PT20 series of industrial pressure transmitters. The series is characterized by its use of silicon piezoresistive technology and its availability in various pressure ranges and output configurations. The PT20 line is widely used in general industrial automation where durable, accurate pressure sensing is required for continuous monitoring and control tasks.

Replacement Considerations

Direct replacements require matching the 0-30 psi gauge range, 4-20 mA output, and 1/4-18 UNF connection. Cross-model substitution within the PT20 series is possible if the suffix codes are adjusted to match these electrical and mechanical parameters exactly.
