3 Indicating transmitter DTR
3.1 Indicating transmitter description
The Indicating transmitter DTR is a specialized computer designed to process data
received from one or two sensors. The Indicating transmitter enclosure (Figure 3.1)
contains a front panel with a backlit Liquid Crystal Display (LCD) and a keyboard. The
front panel swings open to give access for connections and service. Knockout pad-
lock provisions are included in the enclosure’s both cover latches for locks to prevent
unauthorized access.

The sensors send the values of the refractive index n
D
and the process temperature
T to the DTR. The microprocessor system then linearizes the concentration reading
(example in Figure 3.2), and performs an automatic temperature compensation.
