In the entire process industry, pumps of all sizes are used to move a wide variety of liquids. In many processes, the pump (or pump system) plays a crucial role, making it essential to monitor pump performance. By monitoring performance, severe damage and significant operational losses can be prevented.
Differential Pressure Transmitter DE39
Pump performance can be monitored by measuring the pressure difference between the inlet and outlet. This pressure difference indicates how well a pump is performing and highlights areas where performance can be improved. The Fischer differential pressure transmitter DE39 displays the inlet pressure P-, the outlet pressure P+, the differential pressure dP, and the flow rate (volume flow) at a glance via a programmable LCD display.
The flow rate can be calculated by the transmitter and converted into an analog output signal. This output signal can then be used to control the motor and adjust its speed. The second output signal is proportional to the pressure and can be assigned to either the suction or discharge pressure.
Monitoring pump performance improves efficiency, allows the pump to adjust the process autonomously, and with minimal maintenance for decades, reduces overall maintenance costs.
