New app calculates hydraulic oil viscosity at different operating pressures

Free-of-charge web app now online

Webtec has launched a new on-line hydraulic oil viscosity calculator app which 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 up pops the viscosity (cSt). To see the effects on viscosity of fluctuations in temperature or pressure, the user simply alters the values in these fields accordingly, making hydraulic measurement and control easy to achieve.

This free-of-charge Webtec app is the companies’ ‘light’ version. More detailed results, including graphs (some in 3D), can be accessed by logging in (existing users) or registering (new users). Registration takes just seconds and only requires name, company and email address. Importantly, the graphs can be saved for use in the users own reports.
