Pump speed control coupled with improvements at very competitive prices, these factors make the shift into the mainstream choice booster water supply and process applications. However, as most of the water applications, the hydraulic hammer and electromagnetic interference (EMI) will adversely affect its performance and may damage the system components. In China, the booster pump manufacturers make their products in order to get the best performance, are invariably chose Danfoss MBS1900 pressure transmitter. Since 2009 on the market, MBS1900 due to its strong performance and reliability acclaimed.  

Control electromagnetic interference

Booster pump is equipped with a variable speed drive and a pressure transmitter type, the former is used to adjust the pump motor speed according to demand, while the latter is used to monitor water pressure, and the information is transmitted to a programmable logic controller (PLC ). If the system does not have enough water flow or water flow, PLC will reduce motor speed or the motor is on standby to increase pump efficiency and energy savings. However, if you do not have to resist hydraulic hammer and electromagnetic interference pressure transmitter, the pump performance will be affected. Because MBS1900 after repeated applications based on inspection and testing technology, so it does have to resist hydraulic hammer and electromagnetic interference effect.

In  China, the booster pump motor power 5.5KW, 7.5KW or 11KW. However, the greater the pump flow by from the inverter radio frequency (RF) interference is greater, which is the main source of electromagnetic interference, pressure transmitter will adversely affect performance. Because MBS1900 using excellent PCB design and shielded cable,  which can be conducted RF noise kept to a minimum and help to maintain the stability of the output signal. In addition, MBS1900 passed EN61000-6-2 certification standards, and comply with the requirements of industrial environments interference.

Reduce liquid hammer and pressure peaks

In the water supply system, rapid changes in flow velocity (such as start and stop the pump) may produce liquid hammer or pressure peaks. To solve this problem, MBS 1900 uses advanced piezoresistive silicon sensor technology, which provides load pressure is three times the working pressure. To meet the needs of the pump manufacturer, MBS1900 also offers a variety of output signals, pressure range and a range of pressure and electrical connectors.
