Sensors and measurement equipment

Monitor the condition of your hydraulic components and lubricating oils to improve scheduling of maintenance work and avoid critical system downtime. With HYDAC sensors, you are kept up to date regarding oil degradation, viscosity, water content and solids in the oil. In addition, the product portfolio contains sensors for measuring pressure, temperature, flow rate, filter clogging and fill level. For collecting, displaying, processing and saving the measured data, use HYDAC portable data recorders.
