*1:
See figure 10.1 and 10.2 ‘Working Pressure and Process Temperature.
*2:
This ambient temperature is the transmitter ambient temperature.
*3:
Approximate values at a temperature of 25°C (77°F)
*4:
In case of wetted parts material code TW (Tantalum), process temperature limit is up to 200°C (392°F).
Note: The differential pressure transmitter should be installed at least 600 mm below the high pressure (HP) process connection.
However, this value (600 mm) may be affected by ambient temperature, operating pressure, fill fluid or material of the wetted
diaphragm. Contact YOKOGAWA when the transmitter can not be installed at least 600 mm below the HP process connection..
