Sensing Devices and Detectors
The parameters of any system are monitored for indication, control, or both. To create a usable
signal, a device must be inserted into the system to detect the desired parameter. In some cases,
a device is used to create special conditions so that another device can supply the necessary
measurement. Figure 9 shows the symbols used for the various sensors and detectors.
