Webtec has launched a complimentary online hydraulic oil viscosity calculator app that calculates the viscosity of hydraulic oil at different pressures.

Hydraulic fluid suppliers provide oils with different viscosities. These oils are most often badged in terms of their ISO number or grade, where common grades for hydraulic circuits include ISO 32, 46 and 68. Using Webtec’s app, engineers simply select the oil being used, along with the system temperature (°C) and pressure (bar), hit the "submit" button and the viscosity (cSt) is displayed. To see the effects of fluctuations in temperature or pressure on viscosity, the user simply alters the values in these fields accordingly, making hydraulic measurement and control easy to achieve.
