IFO510
The Moisture in Oil Transmitter IFO510 with two analog outputs for different
measured variables and RS 485 Modbus interface as standard, enables reliable and
long-term stable measurement in technical oils. Designed for measurements such as
moisture content in transformer oil, motor oil, lubricating oil, hydraulic oil and diesel
fuels. In addition to a highly accurate measurement of water activity (aw) as well as
temperature (T), the FO 510 calculates the absolute water content (x) in PPM.

4 Description
The FO 510 enables reliable and long-term stable moisture measurement in technic
Moisture in oil can be measured and expressed in two different ways: as an absolute value
or as a relative value.
•Relative moisture is expressed by water activity (aw). Water activity is a relative
measure of moisture in oil and describes the ratio between the actual amount of
dissolved water in the oil and the maximum amount possible at a given temperature.
An aw value of 0 means that there is no water in the oil, while an aw value of 1
indicates complete saturation. Water activity is independent of the type of oil.
•he absolute moisture content is called water content (x) and expresses the actual
amount of water in the oil, whether it is dissolved, emulsified or separated. Water
content is measured in units such as ppm (parts per million) or mg of water per kg of
oil and is independent of oil temperature. To assess the degree of saturation of the
oil, the water content x must be considered in conjunction with the temperature (T).
The calculation of the water content x from the measured values for aw and T is oil-
specific and requires special parameters for the respective oil. We offer the possibility to
adapt these oil specific parameters for different oil types.

The required parameters can either be specified when ordering the FO 510 or
subsequently integrated in the FO 510 using the Service software.
Advantages of the FO 510:
•Fast response time
•Highly accurate measurement of water activity (aw), as well as process temperature.
Measurement is independent of oil type or age.
•Calculation of absolute water content (PPM) possible after input of specific oil
parameters
•Two freely configurable analog outputs as well as Modbus-RTU (RS 485) interface
available).
Programming by software.
With the Service Software incl. USB / Modbus adapter settings like Modbus settings can be
changed, analog output can be rescaled and measured values can be assigned.ility to
adapt these oil specific parameters for different oil types.

7 Installationshinweise
•The direct installation of the sensor is only allowed in the unpressurized
state of the system.
•The sensor must be tightened with a torque of 25 - 30 Nm.
•Tightness of the connection must be checked and ensured.
•It is not permitted to use a sealing ring with a NPT 1/2“
Instead, use a suitable PTFE sealing tape or sealant.
Screw the sensor with the G 1/2" thread pressure-
tight into the line to be measured via a connecting
piece.
Place the sensor tip (hole cap) as deep as possible in
the oil (> 40% of the sensor tip length).
To obtain the shortest possible response time, there
should be a continuous flow of oil.

8 Modbus
The dew point sensor FO 510 comes with a Modbus RTU Interface.
Before commissioning of the sensor the communication parameters
Modbus ID, Baudrate, Parity und Stop bit
must be set in order to ensure the communication with the Modbus master.
The adjustment can be done either with the PC service software.
Modbus communication default values:
•Modbus ID : 1 ( 1 -247)
•Baudrate: 19200 bps (1200,2400, 4800, 9600, 19200, 38400 bps)
•Parity: even (none, even, odd)
•Stoppbit: 1 1,2)
Supported are following functioncodes:
•Funktionscode 03: Read Holding Register
•Funktionscode 16: Write multiple Register

9 Calibration / Adjustment
At the manufacturer
Within the scope of DIN ISO certification, we recommend having the measuring instruments
calibrated and, if necessary, adjusted by the manufacturer at regular intervals. The
calibration cycles should be based on your internal specifications. Within the scope of DIN
ISO certification, we recommend a calibration cycle of one year for the FO 510.
10 Warranty
Defects which are demonstrably due to a factory defect will of course be repaired free of
charge. The prerequisite is that you report this defect immediately upon discovery and within
the warranty period granted by us. Damage caused by improper use or by non-observance
of the operating instructions is excluded from this warranty.
The warranty is also void if the sensor has been opened - unless this is expressly described
in the operating instructions for maintenance purposes - or if serial numbers in the device
have been changed, damaged or removed..
The warranty period for FO 510 is 12 months. Unless otherwise defined, 6 months apply to
accessories. Warranty services do not cause an extension of the warranty period.
If in addition to the warranty service necessary repairs, adjustments or similar are carried out,
the warranty services are free of charge but there is a charge for other services such as
transport and packing costs. Other claims, especially those for damage occurring outside the
instrument are not included unless responsibility is legally binding.
After-sales service after the warranty time has elapsed
Of course, we are also there for you after the warranty period has expired. In case of
malfunctions, please send us your measuring device with a short description of the error.
Please also include your telephone number for any queries.
