Endress+hauser, in germany, manufactures ppressure transducers are offered by endress+hauser, in germany. These pressure transducers are provided with capacitive ceramic sensor for measuring absolute and gauge pressure of gases, vapours and liquids. Some general features of these pressure transducers include:these are extremely stable and resistant to overload; .These simple to mount products enable safe operation and have power supply ranging from 11 to 30 and the output range of pressure transducer cerabar t is 4 to 20 ma; . The pressure to be measured causes a small deflection of the ceramic diaphragm of the sensor. A change in capacitance proportional to the pressure is measured by electrodes on the ceramic sensor. Following are some technical specifications of these pressure transducers which include: ppressure sensor is optionally supplied with din 43650 a/iso 4400 plug or cable end for connecting to a transmitter power supply; .The measurement deviation including hysteresis and reproducibility is 0.5 percent fs.The ranges of ambient temperature and storage temperature are -20 to +85 deg c and -50 to 100 deg c, respectively; . The limiting pressure depends on the overload, whereas the limiting temperature has its maximum at 100 deg c. Some electric the specifications of the product are as follows:* power supply: 11-30 v dc * ripple: 5 percent * process diaphragm: al2o3 * measuring range: 40 bar [max] * rise time: 20 ms * long-term stability: 0.15 percent per year * vibrational resistance: 4m5 conforming to din en 60721-3 * climate class: 4k4h conforming to din en 60721-3
