This Agent has two inputs and is designed to spot a sudden drop in value across a sequence.

In this case, we are looking for a difference between the value of a property between an asset and it's neighbour. We can do this with a spider attachment and a differential algorithm.

We want to set the min property of the differential algorithm to the minimum difference that we would consider 'a problem'.

In this case, let's go with 80kPa.
