measurement point should be within 1 ... 10 bar (14.5 ... 145 psi). The
maximum pressure tolerance of the transmitter is 50 bar (725 psi).
If the gas temperature is higher than the specified maximum operating
temperature of the transmitter, gas sampling and cooling it to ambient
temperature (for example, 20 °C / 68 °F) is recommended. Note that the
dewpoint temperature must be clearly lower than the ambient
temperature to avoid condensation in the sampling line. Sampling from
the process is easy by using Vaisala sampling cell options; see section
Sampling Accessories on page 25.
DPT146 is light in weight, which means that it can be installed in a
sample pipeline in the sampling cells without the need of any additional
mechanical support.
