Intelligent Sensor Management (ISM™) is a technology that involves a microprocessor that is present in the sensors. This chip enables many benefits, including a digital output signal for greater measurement accuracy and on-board storing of calibration data.
This infographic looks at three reasons why digital ISM pH sensors are better in bioprocesses than analog sensors.
- Lower calibration requirements
- Less measurement variability
- Greater measurement accuracy
pH sensors are essential for ensuring fermentation and cell culture processes achieve the desired product quality and yield. Therefore, reliability of sensor measurement and performance are crucial.
Typical analog pH sensors have a number of issues that can impact their dependability, including uncertainty as to when calibration should be performed and inaccurate measurement due to environmental factors affecting the signal that arrives at the transmitter.
pH sensors with ISM technology inform operators when calibration will be required, and the digital output signal is unaffected by the operating environment. In addition, these sensors are designed for minimal zero-point drift after sterilization cycles.
