Overview
The NOSHOK PT20-300PSIC-1-1-2-25-CC is a diaphragm seal pressure transmitter designed for industrial process monitoring. It features a 4-20 mA analog output signal and utilizes a 316 stainless steel wetted materials construction to ensure compatibility with corrosive media. The unit incorporates an isolated diaphragm seal system, which protects the internal sensing element from clogging, freezing, or chemical attack by separating the process fluid from the sensor. This configuration provides reliable measurement in applications requiring high integrity and durability.
Feature Summary
- Isolated diaphragm seal design prevents process contamination of the sensor
- Corrosion-resistant 316 stainless steel wetted components
- Standard 4-20 mA analog output for integration with control systems
Applications
- Chemical processing plants with corrosive fluids
- Pharmaceutical manufacturing requiring sanitary isolation
- Oil and gas pipeline monitoring systems
Procurement Notes
Verify that the specific diaphragm material and fill fluid are compatible with the target process media to prevent degradation. Confirm the required connection size and thread type matches the installation point. Ensure the operating temperature range of the seal assembly aligns with the environmental conditions. Request calibration certificates if regulatory compliance is mandatory for the application.
Selection Notes
Select this model when standard pressure transmitters fail due to clogging or corrosion issues. The diaphragm seal variant is essential for viscous, crystallizing, or aggressive substances. Compare against direct-mount sensors if the process is clean and non-corrosive. Evaluate the need for additional options such as local indication or explosion-proof ratings based on site safety requirements.
Part Context
This component belongs to the NOSHOK PT20 series of intelligent pressure transmitters. The series is engineered for demanding industrial environments where reliability is critical. The PT20 line typically offers configurable ranges and robust construction suitable for harsh conditions. This specific part number denotes a 300 PSI range with a diaphragm seal configuration.
Replacement Considerations
Direct replacement requires matching the original flange dimensions, thread specifications, and electrical connections. Verify that the new unit supports the same 4-20 mA output and power supply requirements. Consult manufacturer cross-reference guides for equivalent models with similar diaphragm seal capabilities.
