NeSSI Probe for Modular and High-Precision Process Sampling

The NeSSI Probe is an advanced sampling probe designed for accurate and efficient process sample extraction in industrial applications. As part of a modular sampling approach, it integrates seamlessly with NeSSI (New Sampling/Sensor Initiative) systems to minimize dead volume and deliver rapid response times. Its compact design improves process efficiency while providing operators with a flexible and low-maintenance solution for demanding environments.

High-Performance Sampling for Industrial Applications

Built for precision, the NeSSI Probe features an optimized flow path that reduces sample transport lag and enables real-time analysis. Its robust construction supports operation in high-pressure and high-temperature conditions, making it well-suited for oil and gas, petrochemical, and refining applications.

For systems requiring efficient routing of sample streams to multiple analyzers, the Sample Distribution Panel (SDP-1) can be integrated to improve system organization and performance.

Modular Integration for Flexible System Design

The NeSSI Probe is designed to integrate directly into modular NeSSI platforms, allowing for quick installation and simplified upgrades. Its architecture supports multiple sensors and analyzers within a compact footprint, making it ideal for applications requiring flexible and scalable sampling configurations.

For applications where rapid sample transport is critical to maintaining measurement accuracy, the Fast Sample System FSS-1 can be used alongside the NeSSI Probe to reduce lag time and improve overall system responsiveness.

Versatile Sampling Across Multiple Applications

This probe supports both gas and liquid sampling, making it suitable for natural gas quality measurement, emissions monitoring, and chemical process analysis. Its ability to operate in harsh environments ensures consistent performance and reliable data for process control.

Low-Maintenance Design for Long-Term Reliability

The NeSSI Probe is engineered for durability with corrosion-resistant materials and a low-maintenance design. Its construction minimizes servicing requirements while ensuring long-term reliability in continuous industrial use.

By providing accurate and uninterrupted sampling, it enhances analyzer performance, improves process control, and reduces operational downtime.
