Process Protection

Protected processes that run smoothly

Siemens devices for process protection form a reliable early warning system. Their robust construction means they are insensitive to dust, dirt, deposits and humidity. Our non-contacting acoustic sensors measure inaudible high-frequency noise emissions, while our non-contacting speed sensors record changes in drive and speed in your piston, turning and conveyor systems.

Pump monitoring and material flow monitoring

With SITRANS DA acoustic sensors for pump monitoring, even the smallest leakages on delivery valves of oscillating positive displacement pumps (e.g. piston pumps) can be detected by measuring cavitation. SITRANS AS100 is an acoustic sensor used for solids flow detection. The AS100 can be connected to a SITRANS CU02, which processes signals from the sensor, providing relay and analog outputs for connection into a process, or it can be connected directly to a PLC analog input

Motion Sensors

All of the MFA 4p motion sensing probes can be mounted up to 100 mm (4”) from the ferrous target, reducing the chance of damage to the probe and the equipment. The probes are not affected by moisture or dust build-up

Process Protection Catalog Specifications Sheets

Process protection is fundamental for safe, high-availability processes. Siemens offers the devices necessary for highly reliable process protection that include flow problems, blockages, sieve and filter problems, and pump cavitation. These protection challenges can be identified early to help avoid unscheduled, costly process interruptions and system stoppages.

USA

Fertilizer

Fertilizers play a critical role in feeding the world's population

A fertilizer production facility in the eastern United States uses volumetric belt feeders to blend the components of the fertilizer they produce
Challenge: If the belt feeder slips on the drive pulley the friction from this slippage will generate heat which can damage the belt and left unattended this friction can generate enough heat to cause a fire. In addition to the maintenance and safety issues, this slippage will also affect the ratio of material being blending causing quality issues
WM300 Motion Failure Alarm setup for differential speed detection, provides the customer with early indication of slippage on the drive pulley so that immediate action can be taken improving overall safety and preventing long down time for belt replacement
