The pressure transmitter is an intrinsically safe apparatus that can be installed in
potentially explosive atmospheres.
The power terminals (+, -) must be connected only to a certified associated
intrinsically safe apparatus.
The electrical parameters (U, I, and P) of the associated apparatus connected to the
power terminals (+, -) must not exceed the following values:
Ui £ 30V
Ii £ 100 mA
Pi £ 1,2 W
Ambient temperature: - 50ºC to 93ºC
NOTE: -50ºC to 93ºC is the certification and "Operative Limits" for the product
family. Refer to individual Specification Sheets for the standard "Rated Condition"
ambient limits for a particular model that, as shown on the data-plate and
certification nameplate, may be less than the certification limits.
Temperature classifications:
IS (ia) 4 – 20 mA / DE
T4 up to Ta £ 93ºC
T5 up to Ta £ 85ºC
