ViscoTron Sensor - VP-300 Series

Manufactured By: Marimex Industries Corp

ViscoTron VP-300

Innovative LED assisted assembly allows the series VP-300 sensor to be manufactured to match customer application requirements by using different lengths or shapes for the extension.

The series VP-300 is available in versions to measure low, medium, high or extra high viscosities. Sensors can be constructed for pressures up to 450 bar (6,500 psi) and temperatures up to 350°C. A PT100 inside the sensor bulb measures the temperature of the process.

Calibration with Newtonian ASTM traceable fluids over 3 decades is standard with 4 decades

These new generation sensors incorporate new features, which have been transferred from the other ViscoTron transducers. The sensor is gravity independent and therefore can be mounted in any direction.

The viscometer measures the drag of a fluid at the surface of the torsionally resonating sensor. The constant amplitude twisting motion creates a constant shear wave . Speed, direction and turbulence of flow have no influence on the measurement. The resonant frequency is dependent on the mechanical construction of the sensor. The microscopic motion is fast enough not to be influenced by outside mechanical vibrations, yet at a frequency of ~500 Hz low enough to provide great sensitivity and resolution even for non-newtonian fluids. The sensor shown in the picture on the front page has been designed for medium viscosities and low pressures. The neck can be up to 300 mm long. This sensor uses the traditional air cooling method for application with high process temperatures.

The sensor is compatible both with the traditional VS-4450 transmitter and the direct digital drive transmitter VT-G144.
