1. Oil pressure and oil temperature importance is obvious The engine usually comes without these probes This is why they are in the kit Like we mentioned before the fuel starvation is one of the things that we all are afraid of Therefore it is good to know what is the fuel pressure in the system For example forgetting to open a fuel line quickly results in a low fuel pressure and Nesis gives a warning In order to avoid the alternator overloading we included the current transducer in the kit 2 4 Other Engines Most other engines have air cooling system Please take the Lycoming engine kit as a starting point and consider which component you do not need and which component you want to add The problems that should be addressed are mostly concerned with the thread size of the oil temperature and oil pressure sensors If you have any questions or you are in doubts please do not hesitate to contact us and together we will find a solution Version 1 1 9 Kanardia 2013 Nesis Purchase Guide 3 Nesis Dual Kits 3 Nesis Dual Kits The Dual Kit is the same as the Basic Kit with an addition of one Nesis display and a CAN cable As it was mentioned before the Nesis Primary display in the Basic Kit has a built in the AHRS GPS unit called AIRU The second Nesis in the Dual Kit does not have AHRS GPS unit inside and we refer to this Nesis as Nesis Slave Figure 2 An example of the Nesis Dual Kit Nesis 8 0 Primary display Nesis2. solid state based sensor suitable and recommended for all engines 6 5 Fuel Pressure Sensors Passive fuel pressure sensor VDO 0 2 bar 0 30 PSI 1 8 27 NPT suitable for all all engines Note The sensor is installed on a pressurized engine fuel line Usually there is no blind connection suitable for the sensor installation Hence you need to provide one Typically the fuel line needs to be cut and T fitting installed Active fuel pressure sensor 0 3 4 bar 0 50 PSI 1 8 27 NPT solid state based sensor suitable and recommended for all engines The same note as for the passive sensor applies Fuel pressure sensor fitting The fitting block has three con nections One for the sensor not visible on the photo and two for the fuel line Two hose clamps tangential worm screw type clamp are needed to tighten the fuel lines the clamps are not provided Note that the blue tube connec tors are pretty long When both are assembled into the block you get a 140 mm long rigid tube 6 6 Fuel Flow Transducers Fuel flow transducer from Becker electronic item 72 01 0 to 100 liters hour We calibrate each sensor to obtain its K number number of pulses per liter Version 1 1 20 Kanardia 2013 Nesis Purchase Guide 6 7 Electrical Current Transducers nO FloScan 201A 6 0 to 113 liters hour 0 to 30 GPH They are calibrated by FloScan 6 7 Electrical Current Transducers Our electric current
