  • Analogue or serial transmission of the measurement data
  • compatible with all ViscoScope inline viscometers
  • Configurable display
  • Time-proportional control or alarms possible

Transmitter for viscosity sensors

Maximum flexibility for optimum choice of measuring instrument: The VS-D250 and VS-4450 transmitters are compatible with all ViscoScope® sensors of types VA-100 and VA-300. Viscosity ranges are covered by the internal resolution of 16 bits over four decades (e.g. 1 - 10,000 or 10 - 100,000 etc.). Even for measurements with very small viscosity difference (example: milk and whey) the transmitters work precisely. Both transmitters VS-4450 and VS-D250 are equipped with a freely configurable display. The transmission of measurement and diagnostic data to a process control system is done via industry standard analog or digital interfaces. The VS-4450 is optionally available with 2 SPDT relays for time proportional control or alarms. The VS-D250 model is designed for DIN rail mounting.

Transmitter for inline viscosity measurement

The VS-D250 and VS-4450 transmitters are compatible with all ViscoScope® VA-100 and VA-300 sensors and their predecessors. This ensures the highest possible flexibility for optimal instrument selection and replacement of older transmitters. The internal resolution is 16 bits, providing excellent coverage of viscosity ranges over 4 decades (e.g. 1 - 10,000 or 10 - 100,000 etc.). The transmitters can also be set for measurements with very small viscosity difference (example: milk and whey). Both models are equipped with a freely configurable display. Transmission of measurement and diagnostic data to a process control system is via industry-standard analog or digital interfaces. VS-4450 is optionally available with 2 SPDT relays, which allow time proportional control or alarms. Constructed in 19" standard, the transmitter is delivered in a panel housing as standard. But other suitable housings, e.g. 19" rack, wall or Ex-d housings are also possible. The VS-D250 model is designed for DIN rail mounting. With an adapter, wall mounting as well as installation in a wall or Ex-d housing is possible.
