Yes, the eTape sensor can be used to measure pourable solids like sand,grain and powder.
You can use a Swiss Machine Pin Header available at SparkFun: http://www.sparkfun.com/products/743
Sparkfun is now carrying the new version of our sensor which has four pins instead of three. The datasheet has been updated and the photos will be updated shortly.
We have a 12 and 24 inch eTape available. Please visit our website for more information: www.milonetech.com
Bit, We have expanded the resistance range (300 to 1.5K ohms)on the latest version of our 8" eTape sensor. The new eTape sensor also includes a reference resistor for temperature compensation when the sensor is used over a broad range of temperatures.

The sensor will hold up fine in dilute ethanol.

The chemical sensor we are developing does not require venting and won’t have any issues with a pressurized tank.
The non-corrosive liquids referenced in the datasheet was meant to address strong acids and bases. The eTape sensor envelope is made of PET, the same stuff water bottles are made from. The concern is not the sensor envelope itself but the adhesive that we use to form the envelope which is susceptible to solvents, acids, etc. The chemical version of this sensor will do away with the adhesive. Since the eTape is a solid state sensor and has no moving parts it is not affected by salt creep, etc.
Will work fine in household sewage.
This sensor will hold up well to salt water/marine environments. We are developing a chemical sensor for use in fuels, solvents, strong acids/bases, etc.
