Description
These pressure transmitters are certified in ATEX and are suitable for use in areas with high explosion risks. Possible explosive zones for the use of pressure transmitters, categories and groups of explosive mixtures of gases and vapors with air – in accordance with the requirements of the Customs Union Technical Regulation TR CU 012/2011 "On the safety of equipment for operation in explosive atmospheres". Explosion protection marking: 0ExiaIICT4/T5/T6.
The PD-39X pressure transmitter is a differential pressure transmitter, characterized by the use of two absolute pressure sensors, which allows it to withstand overloads on the differential from both sides. Considering this feature, this sensor is most rationally used for tasks where the measured differential is of the same order as the static (reference) pressure value.
By default, the sensors have a digital RS485 output, but can also be equipped with an analog output by choice: 4…20 mA / 0…10 V / 0…2.5 V / 0…5 V / 0.1…2.5 V.
An additional application of this sensor can be the simultaneous measurement of pressure in two processes, in which case it is mandatory to use the digital output and obtain 2 pressure signals, 2 temperature signals, and a differential pressure signal.
By default, the sensors have a digital RS485 output, but can also be equipped with an analog output by choice: 4…20 mA / 0…10 V. Through the digital output, in addition to the pressure signal, a temperature signal from the sensor can be obtained, which can be useful for static processes.

Total error for the differential pressure sensor:
The total error for the TEB differential pressure sensor (in % of the measurement range) is calculated as follows:
Example:
Measurement range of the absolute sensor = 10 bar
Measurement range of the differential sensor = 4 bar.
TEB (in %FSO) = 0.1 x 10/4 = 0.25%
