particularly advantageous when setting alarm limits for the maximum particle count per time period.


The data is typically saved in a CSV format allowing for easy interrogation in Excel and transposing into easy to view trends. This data can be backed up locally as well as logged remotely to a PC using HYDAC’s CM Expert.


OIL AGEING


The HYDACLab® HLB 1300 is a multifunctional sensor for online monitoring of the condition of standard oils and bio oils in industrial and mobile applications. The user receives real-time information on oil characteristic deviations in their fluid and can take immediate action in the case of deteriorating operating conditions. Changes in fluid condition might occur due to ageing or mixing with other fluids and are indicated by measuring the relative change in dielectric constant, the relative humidity and the temperature.


INTEGRATION INTO SCADA SYSTEMS The company has recently developed a Fieldbus Communicator Module that connects the Hydac HSI Smart Sensors (CS1000, MCS1000, AS1000 & Hydac Lab) directly into all the major SCADA Fieldbus interfaces. The Fieldbus Communicator Module interfaces to all the major SCADA Fieldbus interfaces including : - CAN, CANopen, CC-Link, ControlNet, DeviceNet, EtherCAT, Ethernet/IP, FIPIO, Interbus, Modbus Plus, Modbus RTU, Modbus TCP, Profibus and Profinet.


For the proactive operator who may be on the other side of the world, the “remote” version of CM-Expert provides constant and timely online information about the condition of the system, also possible via satellite, in real-time. In addition, CM- Expert can trigger alarms automatically, log the actual system condition live, help with the prediction of early failures and help with the planning of maintenance. Costly maintenance carried out unnecessarily early, as well as unplanned interventions could therefore become a thing of the past.


CM-Expert monitors, displays and logs the data transmitted by the sensors and detects changes emerging in the system. Experience developed over decades and the reference data accumulated means that production-relevant parameters, such as remaining service life, service intervals and risks, can be analysed and evaluated


DATA ACQUISITION


HYDAC’s CMU 1000 allows network connectivity and the display of sensor values. It has the potential to connect up to 8 analogue sensors, either HYDAC or a third party, and 8 HYDAC Smart sensors, such as the MCS 1000 MetallicContamination Sensor, AS 1000 AquaSensor, HLB 1300 HYDACLab® oil condition sensor, and is capable of displaying up to 32 measurement channels.


COLLECTION OF DATA


The collection of data is a key aspect in any condition monitoring system. The MCS 1000 presents the CMU with an incremental count of particles whether they are ferrous or non-ferrous. The CMU’s simple programming environment allows for the incremental count from the MCS to be calculated which results in much more practical values, e.g. the number of particles per day or particles per hour for example. The data is thus clearer and more user-friendly which is


CM EXPERT


HYDAC CM-Expert is a powerful monitoring system for use with any standard PC device. Its decentralised configuration makes the system extremely reliable and flexible for use in fluid power systems. Since the controller is specific to the particular purpose, there is no limit to the number or type of sensors, actuators, operating and signal components which can be connected, or to the control tasks and data exchange with other systems.


All common physical parameters can be recorded by the data acquisition unit and processed: temperature, pressure, differential pressure, viscosity, water content, particles, flow rate, level etc.

– in good time and long before a stoppage threatens. The CM-Expert software does not just work with HYDAC sensors and actuators but also of course with other brands without restriction.
