An Ex isolation transducer installed between an AMS EZ 1000 Converter and a measuring
card has an influence on the output signal of the converter. An output signal of less than
-16 V causes the Ex isolation transducer to clip the output signal. This behavior affects the
static and dynamic distance measurement in different ways:
Static distance measurement
The nominal linear output range is slightly reduced when using an Ex isolation transducer.
The maximum output voltage with Ex isolation transducer is approximately -16 V, so the
nominal output voltage of -18 V is reduced by 2 V (see
when planning a static distance measurement.
