GAGE PRESSURE TRANSMITTERS
Model 2808-15B & 2808-16B
1A.1 PRODUCT DESCRIPTION
Gage Pressure Transmitters convert a pressure measurement into a proportional 4-20 mA
or a 1-5 Vdc output signal that can be applied to the input of a controller, recorder,
indicator or similar device. The Model 2808-15B, shown in Figure 1A-1, provides a standard
1/2 inch NPT pressure connection, while the Model 2808-16B shown in Figure 1A-2
provides a 1-inch flush diaphragm connection.
Series 2808 Transmitters are offered in ranges from 0-100 inH
2
O (max.) to 0-5000 psi
(max.). A listing of ranges for the Model 2808-15B is given in Table 1A-A and for the Model
2808-16B in Table 1A-B.
Because of its compact size and light weight, the Transmitter may be installed directly on a
process pipe. For installations that require other mounting arrangements, the Transmitter
may be specified with a universal bracket. This bracket can be used to clamp the unit to a
two-inch pipe or secure it to a support structure.
