Pressure transducers - Cerabar T PMC 131

Endress+Hauser, in Germany, manufactures pressure transducers with capacitive ceramic sensor for measuring absolute and gauge pressure of gases, vapours and liquids. 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. Pressure 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. 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
