A new Sigrist dust emission monitoring
system
Siemens launches the Sigrist StackGuard, an extractive dust emission monitoring system that complies with EN14181 guidelines: using a laser beam, the unit can even be used in wet stacks
New Dust Emission Monitoring System In Compliance With EN 14181 Siemens Automation and Drives - Process Instrumentation and Analytics is launching the Sigrist StackGuard, an extractive dust emission monitor to comply with EN14181 guidelines The British standard BS EN14181:2004 Stationary Source Emissions covers the quality assurance of Automated Measuring Systems (AMS) and is one of the most demanding standards to be developed by the European Committee for Standardisation (CEN)

Safety controller suits Category 4 applications
Siemens has a powerful new fail-safe CPU for its Simatic-S7 300 controllers, suitable for use in safety-critical applications conforming to Categories 1 to 4 (EN 954-1) or SIL 1 to 3 (IEC 61508)
The Sigrist StackGuard is mainly used in wet stacks, where in-situ scattered light instruments cannot be used due to the interference with aerosol droplets.
The StackGuard uses a laser beam which delivers improved levels of sensitivity and allows users to take measurements at concentrations of less than 0.1 mg/dscm without any problems.
The device is easy to operate and users will benefit from a clear text driven menu.
The StackGuard requires less maintenance than earlier versions (such as the CTNR and KTNR).
The service interval has been extended to three months and the new laser light source has a lifetime of several years.
The StackGuard is currently undergoing MCERT accreditation.
The sampling system has not been changed significantly from earlier versions, although the StackGuard large sampling pipe (with a diameter of 40mm) helps prevent insensitivity caused by soiling.
The device, suitable for use even with extremely wet gases, has a maximum heating capacity of 6 kW.
Existing installations can be updated to meet the requirements of the EN 14181 standard by simply exchanging the photometer and the control unit.
