3 Accessories Tan Delta Systems produce and supply a range of accessories and add-ons specifically designed and engineered to work with the Oil Quality Sensor range. Accessories include the following: Oil Condition Display Express Oil Condition Telemetry Gateway Oil Condition Telemetry Gateway Hub Oil Condition Sensor Manifold A range of cables and fittings For details of the full range of available accessories, please contact your distributor.
Page 14: Introduction
4 Introduction The Tan Delta range of Oil Quality Sensors allow real-time reporting of oil quality in virtually any application. The sensor utilises sophisticated electronics to indicate the current condition of oil, relative to an initial profiled condition of new oil. Based on the sensor output, the oil drain-down intervals may be extended on large industrial equipment where the cost of replacing and monitoring the oil is expensive.
Page 15: Measuring Oil Quality
5 Measuring Oil Quality 5.1 Introduction There are a number of ways to describe oil wear and oil condition: Tan Delta Number (TDN) Loss Factor Percentage 5.2 Tan Delta Number To make it easier to monitor and trend the overall oil condition, regardless of your current method, we have introduced the “Tan Delta Number”...
Page 16: Traffic Lights
5.5 Traffic Lights First and foremost, the TDN scale offers a ‘traffic light’ view of oil quality. There is a Green section, an Amber section and a Red section to illustrate OK, Warning and Alarm conditions respectively. The thresholds for these sections can be user-defined for any application. Factors such as likelihood/nature of contamination, how critical the machinery is and manufacturers’...
Page 17: Loss Factor
5.8 Loss Factor A clean oil has a Loss Factor Percentage of approximately 0% and then as the oil changes and degrades this Loss Factor Percentage increases. For most applications, oil would be considered to be degraded at a Loss Factor Percentage of 25% and at the “end of life” at a Loss Factor Percentage of 30% or above.

Page 94: Troubleshooting
11.3.6 Troubleshooting If you are experiencing a communication issue with a Tan Delta sensors following a ModBus installation, please carefully review the following points; Does whatever monitoring system you are using (Monitoring System) use an RS485, 2 wire, half duplex serial interface? Does the Monitoring System use Modbus RTU, not ASCII? Is the Monitoring System set to use the correct COM port (that is connected to the sensor)? Is the Monitoring System set to use 9600 baud, 8 bits, 1 stop bit with no parity?
Page 95 Does the Monitoring System use any non-standard data formats, e.g. inverted data? If so, the system will not communicate correctly. Is the GND lead of the sensor shared with the GND of the Monitoring System? If either part is driven by a completely different power supply, there may be significantly different voltages between the two and they will not communicate.

wear they will both give a small deviation, however as they progress soot will remain linear and TBN will become exponential, therefore we are able to differentiate. The following graphs give examples of different oil degradation patterns allowing you to identify the specific reasons for oil degradation when compared to the expected degradation.
Page 114: Wear Metal Contamination
Figure 77 - Water Ingress It’s often difficult to identify water in oil using lab analysis, because as the data above shows, it is only present in the oil at low temperatures. Often sampling will occur after equipment has been running and so water will have been evaporated. If your sensor shows data similar to this, we recommend waiting until the equipment has been shut down and cooled to ambient, and then running it for several minutes before taking a sample for analysis.
Page 115: Fuel Dilution
12.3.4 Fuel Dilution This is indicated with either a lower decrease in the oil condition over time (ROC) than expected in comparison to the assets usual ROC, or even by an increase in the oil condition that is not directly related to a fluctuation in the oil temperature. Figure 79 - Fuel Dilution In the graph example shown, we have added a comparison line of how a condition such as fuel dilution would look compared to the normal path of oil degradation over time.
Page 116: Tbn Decrease
The example graph provided shows how the oil is degrading faster than expected (the blue line representing the normal expected behaviour) and a point where this contamination becomes evident as the oil condition deteriorated further. 12.3.6 TBN Decrease A decrease in Total Base Number (TBN) is indicated by the exponential decrease in TDN value with time, also described by the downward curve of the plot.
Page 117 Figure 82 - Oil Change Carried Out Correctly If the TDN value does not return exactly to the same point expected of a new clean oil (2), then it is likely that there was some residual amount of used oil remaining in the system which has mixed with the new clean oil.
Page 118: Rate Of Change (Roc)
Figure 84 - Oil Top-Up Intervention 12.5 Rate of Change (ROC) Calculating Rate of Change (RoC) of oil condition is necessary to utilise some of the more advanced algorithms for integrated oil condition logic. You can use the following logic to set up a third-party device to show the rate of change in the oil condition: Instant RoC = Average change in oil condition for last 5 minutes.

Page 121: Introduction
13.1.2 Introduction If using the sensor in the Tan Delta Mobile Oil Test Kit or if the sensor is being used for bench testing, it is important to always clean the sensor properly between samples. In a fixed installation it is not necessary to clean the sensor due to the sensor being in a live oil zone, however in a situation where you have experienced a very heavy contamination we do recommend that you clean the sensor prior to refilling with oil.

13.1.4 Cleaning Procedure – Loctite 7063 or Similar Solvent Unplug and remove the sensor then use absorbent paper to wipe off the excess oil from the sensor tip and thread. While rotating the sensor, force a short blast of solvent up into each of the holes in the sensor nose, and then give the general exterior a wash on both sides as shown in the pictures below: Figure 85 - Cleaning the Sensor (1)

13.1.5 Cleaning Procedure – Odourless Kerosene Unplug and remove the sensor then use absorbent paper to wipe off the excess oil from the sensor tip and thread. Attach a bottle adaptor to a sample bottle and pour in approximately 15ml of kerosene. Screw in the sensor and shake vigorously for 2 minutes to ensure the kerosene washes up around the tip of the sensor.
Page 124: Cleaning Procedure - Deep Cleaning
13.1.6 Cleaning Procedure - Deep Cleaning Some oil testing, generally where there are extremely high levels of carbon deposits and where the sensor has not been cleaned and has been allowed to dry, can result in the sensor being difficult to clean using our standard methods, in this case we recommend a more thorough deep cleaning process cleaning process as follows: Clean sensor using one of the 2 methods described above.
Page 125: Cleaning Procedure - Alternative Solvent Test
13.1.7 Cleaning Procedure – Alternative Solvent Test Clean the sensor using one of the following two methods: Rinse the sensor tip thoroughly in odourless kerosene, as described at 13.1.5. Use the deep cleaning method described at 13.1.6. Test a clean oil sample, repeat the cleaning method used above and then re-test a clean oil sample, the readings from both tests should be the same (or very similar), this proves that using one of the failsafe cleaning methods is working.
