HYDAC Lab¨ HLB 1400, online oil condition sensor

Oil condition
sensors facilitate online monitoring of the oil condition in stationary and
mobile applications.

Monitoring the
oil condition in stationary and mobile applications is essential for the good
function of the hydraulic system.

Oil condition
sensors, such as the HYDAC Lab¨ HLB 1400, facilitate the online condition
monitoring of this oil.

1400 is a multifunctional sensor. It keeps the user informed of changes in
fluid condition as they occur and it can also immediately react to unpermitted
operating conditions.

Thanks to the
information deducted from the sensor, we can make assertions about the
condition of an oil, e.g. ageing or mix with other fluids. We base these
assertions on measured values for:

  • The relative change in dielectric constant
  • The electric conductivity, the saturation
  • The temperature

These measurements
are available as sequential analogue signals and/or switching signals at the
electrical output of the HYDAC Lab¨ (e.g. for activating warning devices or
