We all know that viscosity is a critical property of hydraulic oil as it can impact on the performance and efficiency of entire systems, along with the wear rates of specific components such as pumps and valves. However, measuring or calculating the viscosity of your hydraulic oil at different pressures has never been the most straightforward of tasks. Thankfully, this is now set to change with the introduction of Webtec’s new hydraulic oil viscosity calculator, which is now available online.

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 our 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). Hydraulic measurement and control has never been easier.

If you want to see the effects on viscosity of fluctuations in temperature or pressure, simply alter the values in these fields accordingly.

This free-of-charge Webtec app is what we call our ‘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 your own reports. Why not give it a try now?
