High Temperature Process Viscometer

"Set & Forget" In-Line Viscosity Management from 0.2 to 20,000

Operating Principle

The High Temperature Viscometer consists of Cambridge's ViscoPro 2000 processor and a choice of several sensors.  New ceramic technology allows viscosity measurements up to 370 degrees C and provides highly accurate and repeatable viscosity, temperature, and temperature-compensated viscosity (TCV). Data are output on a visual display, via RS-232 port and a single 4-20mA output channel.

The system can be programmed for up to 40 different fluid settings for rapid product changeovers.  It comes with alarm signals, a control output, and allows the user to control a process with our proprietary "set-it and forget-it" software.  The software has a unique feature that senses process line cleaning and directs the sensor to clean itself.

The HTL392, HTL311, and HTL301 In-line sensors are based on a simple and reliable electromagnetic concept.  Two coils move a piston back and forth magnetically at a constant force.  Proprietary circuitry analyzes the pistons two-way travel time to measure absolute viscosity.
