NOTE: all sensors are tested at ambient environmental conditions, with 47 ohm load resistor, unless otherwise stated. As applications of use are outside our control,
the information provided is given without legal responsibility. Customers should test under their own conditions, to ensure that the sensors are suitable for their own
requirements.
