Sample Probe Module (SPM)
Sample Probe Modules measure the concentration of key components in gas and liquid streams to maintain precise process control. Using sample probes in conjunction with sample probe valves can improve safety as well as sample purity and timeliness. Probe interlocks protect equipment. Valve Interlocks improve safety of operation.
The Swagelok SPM provides a pre-engineered solution for use in online process analyzers. The SPM consists of a welded sample probe (SPW) or retractable sample probe (SPR) and a block-and bleed sample probe valve (SPV).
Choosing a Sample Probe Module
SPW welded sample probes are best suited for use with double block-and-bleed SPVs (SPV61 and SPV62). SPV61 contains a primary block valve, a secondary block valve, and a bleed valve. SPV62 contains the same valve configuration, but adds a mechanical interlock between the primary block valve and the bleed valve.
SPR retractable sample probes are best suited for use with single block-and-bleed SPVs(SPV63 and SPV64), which include safety features that do not allow the valve to actuate while the probe is in service. SPV63 contains a primary block valve, a bleed valve, and a probe spool lock. SPV64 adds a mechanical interlock between the primary block valve and the bleed valve.
"Safe Product Selection:
The complete catalog contents must be reviewed to ensure that the system designer and user make a safe product selection. When selecting products, the total system design must be considered to ensure safe, trouble-free performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system designer and user.
