Simple to install and to use, ADC has optional voltage and serial outputs for data acquisition and / or control functions.

ADC is designed for use with BOC Edwards Active Pirani, Wide Range, Magnetron and Strain Gauges. Its simple Œplug and go¹ installation makes it ideal for integration into OEM equipment, such as vacuum ovens and furnaces, and for monitoring process vacuum in a wide range of laboratory and industrial end-user applications.

Units - Pascals, mbar, Torr or Volts - are selected by the user via simple front-panel push-button controls, and the bright LED display gives clear, long distance readability. ADC¹s measurement range is 2000 to 1x10-9 mbar.

In its standard version, ADC is a simple display unit. For applications that require data logging or control functionality, the Active Digital Controller Enhanced has two set point relays, two analogue outputs and an RS232 interface. These can be used to connect directly to a chart recorder or other logging device for customer records or quality control, for direct control of switches or other instruments, or for connection into a higher level control system such as a programmable logic controller (PLC) or PC-based control system.

Housed in a neat 1/8 DIN enclosure, ADC can be panel-mounted or bench-mounted. It complements the existing BOC Edwards range, giving customers a wide choice of analogue and digital displays and controllers for all applications.

Multi screw pump moves highly viscous heavy oil at low NPSHa

22.02.2024 -

At a tank farm in a Brazilian sea port, two centrifugal pumps were used for transferring heavy oil from storage tanks to road tankers or vessels until February 2020. This required the high viscosity of the medium to be reduced by means of diesel injection, costing the owner at least 2,000 US dollars each day. In addition, the centrifugal pumps regularly broke down due to cavitation damage. The owners decided to initially replace one of the two centrifugal pumps with a NOTOS multi screw pump from NETZSCH. Due to its very good suction capabilities, the selected four-screw 4NS is also suitable for highly viscous media with up to 200,000 cSt, achieving a flow rate of up to 3000 m³/h.
