The Outdoor Oil Leak Detection Sensor has been designed to detect the presence of oil or any non-conductive liquid including fuel, oil, diesel etc. The sensor includes two liquid detectors, one looking for conductive liquids such as water along with non-conductive liquids using an optical sensor.
Features and Benefits
Use to detect oil or non-conductive liquids in outdoor locations or in areas that are susceptible to leaks.
The sensor includes two liquid detectors; one looking for conductive liquids (e.g. water), and the other looking for non-conductive liquids (e.g. fuel oil).
When there is no water but oil/non-conductive liquid present, an alarm will trigger.
If there is water present but no existing non-conductive liquid leak alarm, the sensor will not activate until the water is removed.
Refer to the datasheet for further details on the conductive and non-conductive detection interaction.
* If the sensor is detecting an oil leak before water is detected, the output relay will remain ON. However, if water is detected before an oil leak, the relay will remain OFF**. Until the water has evaporated the relay will remain OFF, and only turn ON if oil is present thereafter.
** The sensor will also detect oil in water providing enough oil is present to force the water away from the optical sensor.
Question: I need more details on the device. Does oil have to touch the sensor? Things like that, .
Answer: Thank you for your inquiry. Our understanding is that this device works via two optical sensors to detect either conductive liquids (water) and/or Non-conductive liquids (oil, gas, etc.). The sensor will alarm in the presence of oil with a minimum puddle depth of 0.04-0.08" (1-2 mm).
According to the manufacturer representative we contacted, the sensor does need to be in contact with the liquid to detect the conductivity and determine the alarm state.
