Description
These pressure transmitters are certified for 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.
Series 33 X Ei: Industrial applications, external thread G1/4”
Series 35 X Ei: Flat diaphragm
Digital output signal of transmitters
The basis of this transmitter is a stable piezoresistive sensor with the latest XEMICS microprocessor with an integrated 16-bit analog-to-digital converter. Temperature fluctuations and sensor nonlinearity are compensated by mathematical algorithms. Using the READ30 program and the KELLER cable K-107, the pressure transmitter can be connected to a laptop or computer. The READ30 program also allows reading data and graphically displaying it on a PC. Up to 128 transmitters can be connected into a single bus system.
Analog output signal of transmitters
The integrated XEMICS processor can operate as a 16-bit digital-to-analog converter for output signals of 4…20 mA or 0…10 V. Signal frequency 400 Hz. Accuracy is limited by signal conversion to 0.05 %FS. For all analog pressure transmitters, a digital output signal is available.

PR – is a relative pressure transmitter, zero reading at atmospheric pressure. Can be used for measuring both gauge pressure and vacuum pressure.
PAA – is an absolute pressure transmitter.
PA – is a gauge pressure transmitter (zero at 1 bar abs.). It is suitable for use where atmospheric pressure changes can be neglected (for ranges above 10 bar) or where a hermetic sensor is required.
