KIT0139 Sensor in Fuel (Diesel)

I have an application to use this sensor in a diesel tank for level measurement.  What spec does it meet when using this sensor in a combustible environment?  Explosion Proof Class 1 Div. 1, MIL-STD-810, both,  and/or other.  Need to know that the construction and use is acceptable by a recognized and accepted standard.  Thanks!
