Fraancesco, Have you tried a T-PAD? Experement with two 10k resistors.
Place a 10k resistor in series in one of the inputs and another 10k
resistor in parallel across both inputs to form a T-junction. While this
will attenuate the output, it will also change the period of the sensor so
you need to find a value that works for both.

Subject: MARK SENSOR
Hi to all
from some weeks I'm using in my station 3 Mark L4 sensors with Larry's
The output signal is very high, and a small events also near me saturats
The gain is at min.
What I do to resolve this problem?
In another station of our network, we use the Mauro Mariotti's ampli board
with the input resistor of 22k and all works fine.
Can I do the same change?
