Model B12-70 Wet Acid Gas Transmitter

DIGITAL DISPLAY OPTION

Series B12 transmitters supplied with the optional LCD have the display mounted to the

enclosure cover with a clear lens protecting the display from dirt and moisture. The display is connected

to the cover with a short ribbon cable soldered to the transmitter circuit board. The digital display is

factory scaled to the transmitter range specified on the order.

The LCD indicates gas concentration directly in PPM or % depending on the range. It is directly

in the 4-20 mA output circuit so that it is a very accurate indicator of the signal being transmitted to

remote equipment. The display should be used for zeroing and calibration instead of the test points

described in the calibration section of this manual.

When removing the cover of a transmitter with the LCD, be careful not to pull on the display

interconnect cable. When you remove the cover, it can be temporarily fastened to the enclosure base as

shown in Figure 9.
