The pressure transmitters Series 26 Y are used in water level measurements that are price-sensitive but still require considerable accuracy.

Technology

Y-series transmitters have an extremely small temperature error. This is achieved by means of
digital compensation of an all-analogue signal path. The gain and the zero point of the gain circuit can be influenced by digital/analogue converters. These receive their numerical values from an EEPROM that is addressed depending on the temperature. A mathematical model for TC zero and TC gain with any order can therefore be determined in the calibration process and stored in the transmitter with a resolution of 1,5 K. The accuracy of the end product therefore essentially depends on the amount of testing and the linearity of the measuring cell.
With the Series 26 Y, the monocrystalline silicon measuring cell is reliably protected from the
measuring medium by a stainless steel diaphragm. The steel diaphragm itself is protected from
mechanical influence by a plastic cap, and has outstanding performance features with regard to
accuracy and stability due to its large diameter of 17 mm.
