IV. Functional Description

The core function of the 05701-A-0361 pressure sensor is to monitor real-time pressure fluctuations within process systems. It converts physical pressure into electrical signals recognizable by DCS or PLC systems and continuously transmits pressure data. When on-site pressure exceeds preset thresholds, it works in conjunction with the control system to trigger alarms or interlock protection, mitigating equipment safety risks associated with overpressure. It serves as a critical front-end detection component in process safety interlock systems.

  V. Application Scenarios

Used in oil extraction, natural gas transmission, chemical refining units, hazardous material storage monitoring, and oil and gas pipeline pressure monitoring. Applications primarily involve Safety Instrumented System (SIS) maintenance, spare part replacement, and system retrofitting in explosion-proof zones.

　VI. Selection Recommendations

1. Confirm that the installation site is an explosion-proof zone; verify the medium type and pressure range to match the sensor specifications.

2. Confirm the installation thread size to ensure compatibility with on-site piping.

3. Check the control system’s signal input type to ensure the output signal matches.

4. For facility maintenance scenarios, stocking up in advance is recommended to minimize downtime caused by waiting for parts.

VII. After-Sales and Service Support

Supplied spare parts undergo comprehensive functional testing prior to shipment and come with a warranty. Actual product photos can be provided before dispatch, and inspections are supported. Technical documentation and remote technical guidance are available should any questions arise during installation or operation. In-stock items can be shipped promptly; inquiries regarding matching spare parts from the same SIEGER safety instrument series are also welcome.
