Model 269


Low Differential Pressure Transducer

Product Overview

Setra's Model 269 transducer is the highest accuracy solution for monitoring differential pressure in critical environments.  Its 0.25% FS accuracy is calibrated using the "End Point Method" which improves linearity when compared to competitive transducers which use the "Best Fit Straight Line Method".  The 269's calibration is tamper proof by utilizing a removable process head that eliminates inadvertent adjustments while allowing in-situ calibrations without removing the process tubing.  Calibrations can be performed automatically when performed with Setra's MicroCal outfitted with an expert system.  The 269 offers multiple mounting configurations, including DINrail, for quicker and easier installation.

High Accuracy for Demanding Pharmaceutical Applications - The Model 269 differential pressure transducer uses a dead-ended capacitive differential sensing element with superior linearity and enhanced thermal performance to ensure the highest accuracy and reliability in your most critical and demanding applications.

Secure and Fast Calibration & Service - The Model 269 is designed specifically for the pharmaceutical industry's stringent calibration guidelines in mind. The 269 has a removable process head to allow technicians to perform calibrations without cutting pneumatic tubes during each calibration cycle. The 269 also provides secure calibration; in order to make sensor adjustments, the unit requires a calibration key to prevent unauthorized personnel from making unwanted changes.

Flexibility in Installation - The Model 269 is available in both a base and DINrail providing the installer with flexible mounting options. The base mount allows the sensor to be installed anywhere, whereas the DINrail configuration is designed to maximize space efficiency in a pharmaceutical panel.
