Discussing the Hardware

FAST CT SENSOR

The 5127 Fast Conductivity Temperature sensor consists of a Fast Temperature sensor (5316) and a Fast Conductivity sensor (5346) potted together into one stainless steel tube. The mechanical drawing shows that the sensor is designed to be mounted on the SCAMP and is bent such that it can be closely aligned with other sensors. The image below shows a picture of this sensor.

The Fast CT sensor is a combination of the sensors used in the Fast Temperature sensor (1) and Fast Conductivity sensor (2). The position of the Fast Conductivity sensor's electrodes is adjusted to be slightly ahead of the Fast Temperature sensor and 1 mm away. Please refer to the sections above for descriptions of these two sensors and wiring diagrams.

The Fast CT sensor is supplied when accurate alignment of the Fast Conductivity and Fast Temperature sensors is required or when many sensors are mounted on the SCAMP.

The Fast CT sensor provides the two fast sensors used by the fast temperature channel and fast conductivity channel.
