earDetect Oil Debris Sensor 2. Product overview 2.1 Description of the Product WearDetect is a condition monitoring sensor that detects particles of ferrous metal in oil. Deposited metal particles in the oil from gears, bearings or other metal contacting surfaces are used to indicate an overload condition, providing an early indication of mechanical failure.
To cater for the different sizes of sump plug found, Gill offer a range of the most popular thread adaptors, one of which must be chosen alongside selecting the sensor for correct installation.
Also shown below is the Inflow installation kit. These kits contain the adaptor plus isolation valves and supports and can be supplied for either 1” or 1.5” pipe diameters. These options require the sensor to be fitted with an M20 x 1.5 fitting available from Gill - part code 4212-PK- 502, 4212-00-160-100 & 4212-00-160-150...

Fit the sealing washer to the adaptor or use a suitable thread sealant for NPT adaptors Fit the thread adaptor to the equipment tightening by hand Fully tighten to 50Nm using the correct spanner (see Gill Adaptor instructions) Fit the sensor into the adaptor, pushing passed the o-ring seals fitted to the sensor Once the rear surfaces of the sensor head and adaptor are level with the sensor fully inserted tighten the grub screw using a 2mm hex key to a torque of 1Nm.
Oil Debris Sensor 4.3 Sensor Electronics Gill recommend positioning the sensor electronics in a position where vibration is minimised and, with regard to the display model, where the display is visible. Sensor with display Two diameter 6.4mm mounting holes are provided for fixing the sensor electronics to a fixed surface. The mounting holes are accessed by removal of the lid.
4.4 Sensor Cabling Gill recommed a maximum of three sensor head cable turns to avoid cable coiling prior to installation. Sensor to electronics cabling may be shotened and re-attached only on models with display using the supplied bootlace ferrules for re-connection. Cable length must not go above 3m to preserve signal reliability.
Oil Debris Sensor Cable Protection: Sensors with display models An optional conduit kit (Gill part No. 4212-10-051-X) is offered for additional cable protection for the Sensor with display models. For installation, follow the guidance below: Fit conduit before sensor is fitted to the thread adaptor Remove your Oil Debris Sensor from the Sensor with display electronics enclosure, disconnecting the wiring from the termination block.

earDetect Oil Debris Sensor The “disable coarse channel” option is switched off by default, meaning the coarse channel is enabled. Disable Water Contamination/Temperature Channel Select the “disable fine channel” option to make the Water Contamination/temperature channel inoperable. The “disable Water Contamination/Temperature channel” option is switched off by default, meaning the channel is enabled in it’s out of the box condition.
earDetect Oil Debris Sensor Input the desired temperature values into the dialogue box and press the set button to write the value to the Temperature alarm settings sensor. Continuous temperature min / max settings See below for settings for high / low alarm. For the temperature alarm, set the high and low settings between those shown below For a continuous temperature feed, set the range of temperature measurement as shown below.

Note: The numbers in the boxes displayed above are internal sensor counts, not percentages. For average chip detec- tion Gill Recommend the Coarse 100% be set to 250. Fine 100% can be set to 750 for maximum fine channel range. for customers trending the output.
Page 28
earDetect Oil Debris Sensor Full Scale Coarse The “full scale coarse” operation will gauge the output of the sensor to the desired level with the maximum amount of coarse debris applied to the sensor (100% Full Scale Deflection). Add some coarse debris to the sensor head (This should represent what you would constitute to a 100% failure).
Note: The numbers in the boxes displayed above are internal sensor counts, not percentages. For average chip detection Gill Recommend the Coarse 100% be set to 250. Fine 100% can be set to 750 for maximum fine channel range. for customers trending the output.

earDetect Oil Debris Sensor Note: Oil dielectric measurement is not available where the sensor to be used has an NPT thread fitting. WearDetect measures the dielectric property of the liquid surrounding the sensor element. This is used to provide information about dielectric changes such as a no-oil condition (air) or water in oil condition. When a Water Contamination alarm threshold is reached, the sensor output is triggered to full scale.

earDetect Oil Debris Sensor Select the oil tab from this new window. Fully immerse the sensor element in the selected reference oil (fresh oil) to set the Water Contamination reference value. The value should be normalised to 1000 once set. gillsc.com...
Page 32
earDetect Oil Debris Sensor Press the “Set Water Contamination Reference” button and this will return the value to 1000. Note: This Clean Oil Reference is only valid for the bench-top calibration process, and will need to be re-calibrated once the sensor is installed. Now remove the sensor head from the oil, wait 3 seconds, and take note of this value.
Page 33
earDetect Oil Debris Sensor To migrate the risk of false alarms, it is advisable to establish the threshold at the highest level allowable. Thoroughly mix at least 10% by volume of water into the oil sample. Fully immerse the sensor element into the mix and record the displayed Water Contamination value.
