oil temperature

Christian has devised a circuit for indicating the oil temperature and offers them now. Here are
Text:

goal was a simple, affordable and reliable solution to an optical Öltemperturüberwachung. I'm using a known electronics engineer developed a circuit and been built up several times on PCB. Again and again, small changes are made, measured, tested in the kitchen with heated salads (the house still smells of frit Bude !;-)), until we find my opinion the best. I have finally realized the whole thing with a window comparator and a flip-flop, which ensures that at high oil temperature, the LED flashes. Most sense, the version with a Duo-LED has emerged. It will light yellow oil at temperatures up to 60 ° C and flashes red from 120 ° C. As a temperature sensor is a high-precision platinum sensor comes with a tolerance of 0.1% used. This withstand temperatures up to 200 ° C - a temperature at which our engines already in engine heaven ... The circuit is poured into a plastic housing with 1 meter cable for power supply, 1 meter cable for two-color LED that is already built and soldered soldered sensor cable. If interested

can I offer the following options:

12V/6V circuit with battery (fully assembled, tested and sealed in case "small" including sensor) -> 50, - EUR
circuit for 12V/6V without battery ( fully assembled, tested and sealed in case "large" including sensor) -> 58, - EUR
DIY for 12V/6V with battery: PCB, components, sensors, cables, two-color LED, case "small" and component placement (you have to solder yourself) 30, - EUR
12V/6V for yourself without battery: PCB, components, sensor , Cable, Duo-LED, housing "large" and component layout (solder you have yourself) 38, - EUR
Different set points for 5, - EUR, because I found the resistors, which are responsible for the switching points, first determine and again.
Other versions (cables, connectors, etc. ..) after consultation

The sensor cable do I shortly before soldering and potting like to the desired level. If nothing further desired, the sensor cable is about 1.40 meters long!

Here some pictures of my solution to block the sensor. I shot an adapter, which replaces the dip stick and poured the sensor has. The whole thing is connected with a high-quality initiators cable, which meets the IP67 protection class and therefore not susceptible to moisture. If interested, I can also offer the initiators cable for the realization of their own projects.
must now be only the weather is better so we can test the circuit finally in practice! :-) Directed
