Differential pressure transducer P 29

4-20 mA0-10 V0-5 V

TÜV-certified differential pressure transmitter for measurement for natural gas applications without Ex-zone requirements. Special features • High level of accuracy and long-term stability through automatic zero-point calibration • Multi-coloured Display with keypad for easy configuration of the measuring range, analog output, time constants and units (optional, also via USB/PC) • Measurement of differential pressure or volumetric flow / flow rate possible • Multilingual menu (English/German/Italian/French) • Suitable for top-hat rail mounting and wall surface installation • Silicon-free materials for parts in contact with medium • Selectable output signal 0 .. 10 V, 0/4 .. 20 mA or ± 5 V • Selectable attenuation of the output signal from 0 .. 60 s • Can be calibrated • High level of overpressure protection even in the smallest measuring ranges protects the instrument against pressure peaks or incorrect operation • Quick and easy start-up due to automatic zero-point calibration • Pressure Ports: Laboratory nozzle optional with cutting ring connectors The pressure transmitter is particularly suitable for measuring volume flow of gaseous hydrocarbons such as butane, methane etc. in industrial furnaces or combustion plants. The instrument does not generate any ATEX zone as its design and technical safeguards mean it poses no ignition hazard. The measuring range is scalable in the range from 10 .. 100 %. This can be performed using a keypad and display (optional). The measured values can be displayed in all standard units. A selectable time constant allows the transmitter to be adjusted perfectly to the pressure conditions and thus ensures a stable output signal.
