Analog Receiver Gauges

Siemens Industry, Inc.

Description

Analog receiver gauges are round dial instruments that indicate the output signal from a

pneumatic transmitter. The gauges are available in three sizes. The 1-1/2 inch gauge is

pipe mounted only. The 2-1/2 and 3-1/2 inch gauges are flush mounted, usually in the

central control panel.

Features

• Snap-in ring for 1-1/2 inch gauge, 1/4 turn on 2-1/2 and 3-1/2 inch gauges.

• Linkage consists of bourdon tube, geared linkage, return spring and pointer.

• Points on the gauge dial indicate corresponding psi (kPa) measurements.

Analog Receiver Gauges Technical Instructions Document No. 155-023P25 May 20, 2021 Operation As the air pressure increases, the curved bourdon tube, which has one end fixed, tends to straighten out. This action moves the precision gear linkage that is attached to the end of the tube and, in turn, rotates the pointer in a clockwise direction. As the pressure decreases, the tube tends to return to its normal curved position reversing the pointer's direction of movement. Table 1.

Analog Receiver Gauges Installation Technical Instructions Document No. 155-023P25 May 20, 2021 1-1/2-inch gauges have a 1/8-inch NPT male fitting for pipe mounting. 2-1/2 and 3-1/2-inch gauges are flush mounted on a panel. These have a barbed fitting for 1/4-inch OD poly tubing. For panel cutout dimensions, see TB 196, Cabinet Cutouts Technical Bulletin (155-223). Calibration Measure the temperature (or humidity or pressure) that the transmitter is sensing.
