The
ViscoScope VS-B450 The ViscoScope transmitter VS-B550 is a new development and utilises the latest integrated technology available. It is a forward looking development, which has been designed in such a way, that future developments can easily be added and integrated. Especially in conjunction with our ViscoScope VL-300S sensor, unique customer requirements can now be accommodated. Safety features, which are part of the integrated system, make applications possible, which could previously not be handled. The integrated safety features also make it possible to cover all ranges and temperature classes with one basic sensor design. The ViscoScope VS-B450 electronic is configured as a "blind" unit. A single LED provides immediate feedback to the user of internal alarms, sensor operation and overall functionality of the electronic. The system features the capability to verify the calibration and functionality of the system in-line. No special calibration fluids are required to accomplish this. The only requirement is, that the sensor is free of any fluid. Once the sensor is considered clean, a menu choice in the VisConfig software puts the sensor into self check mode. Calibration and functionality of the sensor is indicated by the software and can then be verified. For data collection purposes via a PC compatible computer our ViscoView® software is optionally available. The electronic continuously monitors the process temperature and in high process temperature applications also monitors the coil temperature of the sensor. The fast loop PID control system, which controls the sensor, provides a linear response and includes anti-wind-up control. In situations where the sensor is potentially at risk, the above features enable us to provide a safe shut down and restart of the sensor. |
Using surface mount components provides for a compact design. The standard size can be accommodated by many housings, which are available in many choices. The dimensions are 3HE x 21TE and approximately 180 mm deep.
Optional multiple analog as well as a serial interface (MODBUS-Protocol) guarantee the connection of the ViscoScope VS-B450 electronics to any process control system, a PC or a recorder. The serial interface automatically switches to the front of the electronics, if the special optional cable is being used. This provides easy access at the front of the electronics for field side configuration and quick data collection via a PC computer or PDA. The front plug also enables factory trained service personal to fully examine the internal operation of the entire system, without even removing the electronics from its housing.
The ViscoScope VS-B450 electronics is compatible with the ViscoScope sensor VA-300. It is configured as a 19" rack design and is available in different housing configurations. It is factory upgradable to model VS-4450.
