Task:
Dampers are used to divert, modulate and isolate gas streams in power generation plants. Different types such as diverter dampers, stack dampers and louver dampers are commonly used. They all operate under extremely demanding environmental conditions.

Their function is to handle a high temperature gas stream, i.e. the exhaust stream of a gas turbine, and direct it totally or partially to the HRSG (heat recovery steam generator) or to the bypass stack.

For safety and perfect function of the plant, reliability is extremely important. The exact position of the damper is an important process parameter that has to be monitored continuously.

Solution:

• Accurate and reliable position feedback
• Robust and compact design
• Capacitive design provide high resistance to environmental influences
• Intrinsically safe versions available
• Easy and quick installation
• Simple commissioning due to on-site parameterization

Task:
A glass plant is a large consumer of electric power, espcecially when the furnace or furnaces use electric boost. The power consumption of the plant needs to be monitored on a continuous basis so daily operating costs can be calculated and controlled.

Solution:
A210 Power Meters are mounted on DN rail adapters and located where electric supply lines enter the building.

Task:
A major valve manufacturer needs to monitor the Power Factor of their inductive heating furnaces.

Solution:
A210 Power Meters are used to monitor the Power Factor of their inductive heating furnaces. Electric energy consumption is optimized which lowers operating costs while at the same time maintaining product quality.

Three values such as Voltage, total Current, phase Current, kWatt, kVAR, Active Power (Watts), Reactive Power (VAR), and Power Factor (pF) can be shown on the A210 triple display. These values allow you to monitor the running system.

The A210 also has two alarm functions, which can be set up by the user for Power Factor limits. If something causes the power factor to deviate, it will trigger an alarm and indicate the actual measurements when an alarm was triggered.

The two alarms can be set at different levels: low value as a warning and a higher value for a possible corrective action.

This alerts the operator of a potential problem and provides a cost effective way to prevent lost production.

Task:
A machine driven by an electric motor consumes a certain amount of active power (Watts). For example, a newly rebuilt 3-phase motor may use 4.0 kW while running.

As soon as the power consumption increases to 4.2 kW it may indicate that the motor bearings are going bad or some other machine component is beginning to fail.

Solution:
The A210 Power Meter is a very cost effective device for monitoring the performance of electric motors in critical applications where expensive downtime cannot be tolerated.

The A210 can be installed near the motor either in the optional NEMA 4 housing, on a DIN-rail using the optional DIN rail adapter, or in a ¼ DIN panel cutout.

The A210 is connected to monitor voltage and current of the electric motor. The motor can be single phase or 3-phase, 3- or 4-wire . PT and CT ratios can be easily programmed from the front panel.

Three values such as Voltage, total Current, phase Current, kWatt, kVAR, Active Power (Watts), Reactive Power (VAR), and Power Factor (pF) can be shown on the A210 triple display. These values allow you to monitor the running system.

The A210 also has two alarm functions, which, for example, can be set up by the user for Watt and VAR limits. If something causes the motor power consumption goes up, it will trigger an alarm as soon as the setpoint is reached, and indicate the actual measurements when an alarm was triggered. The two alarms can be set at different levels: low value as a warning and a higher value for a possible breakdown.

This alerts the operator of a potential problem and provides a cost effective way to prevent unexpected breakdowns and lost production on any type of machine operated by an electric motor.

Task:
When a motor is received for service or rebuilding, this major electric motor rebuilding facility operates the motor and measures and records
Watts, VAR, Power Factor plus other variables. After the motor is rebuilt or serviced, they test the motor again and measure the same variables. This way they can demonstrate to their customer how much less energy the motor consumes, and its higher operating efficiency. They can also establish a historical record of operating parameters for motors that are serviced regularly.

Solution:
The A210 Power Meter is a very cost effective device for monitoring the performance of electric motors.

The A210 is connected to monitor voltage and current of the electric motor. The motor can be single phase or 3-phase, 3- or 4-wire . PT and CT ratios can be easily programmed from the front panel.

Three values such as Voltage, total Current, phase Current, kWatt, kVAR, Active Power (Watts), Reactive Power (VAR), and Power Factor (pF) can be shown on the A210 triple display. These values can be wriiten down or logged with the optional EMMOD datalogger.
