OIL  QUANTITY  SENSOR  OVERVIEW

A "complete" oil quantity system consists of the OSE-1 electronics package and an oil quantity sensor.   The oil temperature sensor is now (optional), and is customer selectable (by popular customer demand).  This oil quantity sensor with its associated electronics package will give the pilot a real time oil quantity while in flight or on the ground. This system is not meant to replace any other traditional methods of checking oil quantity. It is a new device that the pilot of a small aircraft can use in flight that he or she never had before. It will also measure oil temperature if that option was selected at purchase. The electronics enclosure features two analog outputs, one for oil quantity and the other for oil temperature. It also features a four digital output alarms (open collector type) for sensor malfunction, oil level warning, oil level caution, and over oil temperature. You may program the alarm trigger values for those outputs and choose a scaling for both analog outputs. 

 

You may choose to display the oil quantity and temperature on your existing EIS or EFIS system, or utilize our model AG6 pictured above.  Our AG6 is approximately the size of a postage stamp and will also give you alarms.

 

Presently, we have two types of oil sensors available, one for standard Lycoming engine oil pan fittings and the other for standard Continental engine oil pan fittings. The sensor will fit quite a number of engines, oil pans, oil sumps and oil containers. Presently, the length of sensors are custom built. The sensor's length must be determined by the customer at the time of purchase. Later, we plan to build them up ahead of time as we create a database of standard lengths ordered. A list of our available sensor fittings will be available in the purchase area on our Website. Sensors with other fitting types may already be in our design schedule.

 

OIL TEMPERATURE SENSOR (optional)

Our standard oil sensor does not include the oil temperature sensor.  This has changed because of popular customer requests.  It is (NOW OPTIONAL).  This option is customer selectable at the time or purchase. 

 

WHY PURCHASE THE OIL TEMPERATURE SENSOR OPTION?

The temperature reading is a bit different from the standard engine oil temperature.  It measures the Oil Sump temperature.  The sensor gives you a good indication what the oil temperature is in the oil sump area. In general, we have found that this temperature reading is different from the engine oil temperature.  In our O360-A1A engine, the oil sump temperature rises faster than the engine oil temp.  It also runs a bit hotter than the engine temp, until you get up closer to your cruise phase of flight.  It also gives you a good indication whether the temperature is boiling off excessive water that  remains in your sump. It also makes a good back up for the normal engine temperature reading.

INSTALLING the OIL QUANTITY SENSOR (from the TOP or Up-Side-Down)

You may install the sensor from the top side of your oil pan or oil container but, . . please be aware of two situations.

 

First, please understand that the temperature sensor is mounted in the base of the sensor. This being the case, it will not function properly because it will not be immersed in the oil unless the oil tank is always full. 

 

Second, also be aware that when you calibrate the oil quantity sensor by adding your quarts of oil, the sensor may not sense your lowest oil level. If this is the case, your sensor tip may not extend into the oil at the very bottom of your oil pan when adding your first quart. The oil level must be between the sensor base and the sensor tip for the first "quantity" of oil. If this is the case, you might try adding two quarts as your "increment" instead of a one quart increment. This may allow you to get the oil level beyond the tip of the inverted sensor.  It is up to the installer/customer to determine where your lowest oil level is for your installation for an inverted sensor installation.

 

WILL this  OIL  SENSOR  FIT?

We would like to make certain that the sensor that you order will fit your aircraft.  If you order one of our standard available sensors, and the sensor never had oil in it, or it didn't have scars from installation, we may be able to refund your money if you make a mistake ordering.  However, if you order a custom made sensor and find that it does not fit, we will not be able to refund your money for the sensor portion of your order.
