2 ViscoScope VS-4450 Analog drive viscosity transmitter for ViscoTron and ViscoScope transducers ViscoScope series viscosity transmitter 4-line backlit LCD display Viscosity, temperature and frequency measurement Fast PID control loop for viscosity sensor 4 outputs slots plus front panel RS232 interface Up to 4 to 20 ma outputs Optional RS485 serial interface MODBUS protocol

3 ViscoScope VS-4450 / VS-B450 Alphanumeric display 4-line backlit LCD 4 optional outputs RS485 interface Front panel RS232 Modbus Protocol Local 3 button configuration The transmitter VS-4450 has an alphanumeric display, alarm LED s and push buttons for configuration. The model VS-B450 has the same functionality as the VS-4450 but only has the watchdog timer single LED indicator. Both transmitters can be configured with a PC or optional graphical touch panel. For transmission of the measured parameters standard analog and serial outputs are available. The transmitter can be located up to 1000 meters away from the sensor. If the sensor is located in a hazardous area, safety barriers will be used for either ATEX or CSA International approval. The available approval ratings for the complete system with safety barriers are: ATEX: II 1/2 G EEx ia IIC T3 T6 and CSA International Class I, Div I, Group C and D compatible with: ViscoScope VA-100 VA-300 ViscoScope VS-4450 panel mount transmitter with protective door ViscoTron VP-1000 VP-2000 VP-3000 ViscoScope VS-4450 and VS-B450 transmitters in 19 Rack
