Keller 23 SY/25 Y temperature-compensated pressure transmitters
The Keller 23 SY/25 Y pressure transmitters feature extremely small temperature error, which is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1.5 K wide.
The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the analog signal path depending on the temperature. Each temperature is the ‘calibration temperature’ for this transmitter.
These pressure transmitters are highly resistant to interference from electromagnetic fields, and limits of the CE standard are undercut by a factor of up to 10 with conducted and radiated fields.
The pressure transmitter has various models with differing constructions and measuring ranges. The floating mounted sensor with internal O-ring is used for low ranges of 0.2 to 2 bar, while fully welded sensors have ranges of 0.5 to 1000 bar, including flush diaphragm models. They can be absolute, barometric or gauge (positive or negative pressures). The transmitter output is analog in either voltage or current form.
