BE2100 Noninvasive Biomass Monitor for BE2100 Sensor
Readout and Control for BE2100 Sensor
The BE2100 base unit accommodates one BE2100 noninvasive optical biomass sensor (sold separately). The BE2100 Base Unit supplies power for the sensor and its readings can be viewed on the fluorescent display. The operational parameters for the sensor can be adjusted through the keypad interface.
Software Included
The BE2100 base unit also allows you to communicate digitally with a BE2100 sensor using either an RS232 or USB interface cable, enabling straightforward integration into a fermentor or bioreactor control system or connectivity with a computer. The included software program provides intuitive controls and the ability to track growth in real time. The software can also calibrate the sensor to any desired units (OD, g/L, cells/mL, etc.) as well as track important events (e.g. inoculation, nutrient additions).
Simple Command Set
As an alternative to running the standard computer program, a well-documented serial command set is provided for communicating with the sensor using simple commands. The commands can be called from within any other computer program or control system that has the ability to send and receive serial commands. This makes it easy to integrate the BE system with other instrumentation. A LabView® instrument driver is also available on request.
Analog Output
The analog output at the rear of the BE2100 base unit provides signal current (4-20 mA) proportional to the reading of the sensor. The correspondence between the analog output and the sensor measurement is adjustable (using the “range” setting). The six logarithmically-spaced settings span range values from 0.01 to 1000. The analog output can be easily converted from current (4-20 mA) to voltage (2-10 V) using provided resistors. A second analog output is proportional to the exponential growth rate (in units of 1/hours).
