The AST-100TSY is a simple solution to viscosity control when special features or elaborate operator interfaces are not required.
The AST-100TSY — coupled to a simple, remote, loop-powered indicator scaled in engineering units — allows an operator to make better and faster decisions because he/she does not have to rely on unreliable or inconsistent measurement techniques.
The AST-100TSY is also “ideal” for low cost, seamless integration of viscosity measurements into factory floor, automated control systems (PC, PLC, DCS, etc). Our new AST-100TSY includes a powerful, digital communication feature (Modbus RTU) that allows up to 10 viscometers to be networked into a single, reliable, multi-station, viscosity measurement system. It is easily integrated into a process controller using a single twisted pair wire.
Optional AST-300SY Single-Station Controller
