Claim: CLAIM The ornamental design for a pressure transmitter, as shown and described.
Description: FIG. 1 is a perspective view of the pressure transmitter;

FIG. 2 is a front elevational view of the pressure transmitter;

FIG. 3 is a rear elevational view of the pressure transmitter;

FIG. 4 is a top plan view of the pressure transmitter;

FIG. 5 is a bottom plan view of the pressure transmitter;

FIG. 6 is a right side elevational view of the pressure transmitter;

FIG. 7 is a left side elevational view of the pressure transmitter; and,

FIG. 8 is a perspective view of the pressure transmitter in its environment of use. In this figure, elements which are not a part of the claim are illustrated in dotted lines.

The article is an apparatus for measuring a relative pressure, that is, a pressure after comparing an introduced pressure with an atmospheric pressure, vacuum pressure, or other source of pressure, and for converting the pressure into an electrical signal sent to a remote site, and for indicating a value corresponding to the electric signal.

The horizontally long rectangle located in the middle upper part of the body in the front view is a liquid crystal indicator, which indicates a measured pressure value. The circle surrounding the liquid crystal indicator is made of transparent material, protecting the liquid crystal indicator and permitting viewing of information indicated on the liquid crystal indicator from outside. The circles near the middle upper part of the body in each of the right and left side views are conduits for receiving an electric power cable, for providing electric power to the article and also for transmitting the pressure signal out to the remote site.

The central circles of the three small circles vertically aligned along with the respective right and left edges of the lower part of the body in the right and left side views are pressure ports for guiding liquid to be measured. When this article is installed, one of the pressure ports shall be connected to a pipe where the liquid to be measured is running, while the other pressure port which is connected to the pipe will be closed.
