Description
These pressure transmitters are certified according to 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 gas and vapor mixtures 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-33 X Ei series is used for measuring differential pressure.
Digital output signal of the 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 displaying it graphically on a PC. Up to 128 transmitters can be connected into a single bus system.
Analog output signal of the 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 is 400 Hz. Accuracy is limited by signal conversion to 0.05% FSO. A digital output signal is available for all analog pressure transmitters.
