The P-5215 Differential Pressure

Transmitter accurately measures

differential pressure and

converts the measurement into a

proportional 3 to 15 PSIG (21 to

105 kPa) output signal. This

instrument can be used in a

variety of control applications

including static, velocity, and

differential pressure control.

Operation

The P-5215 is used with the low

input acting as a reference less

than, greater than, or equal to

atmospheric pressure. As the

differential between the low and

high inputs increases, an

internal mechanism will

proportionally increase the

output signal of the P-5215. The

output at zero differential is

3 PSIG (21 kPa). When the

differential reaches its

maximum, as defined by the

range, the output will be

15 PSIG (105 kPa).

Note: The P-5215-4, with a

range of -.05 to .05 in. WG

(-12.45 to 12.45 Pa), is an

exception to this rule. The

output for the P-5215-4 is

3 PSIG when the pressure to

the high input “H” connection

is .05 in. WG

less than

the

pressure to the low input “L”

connection, and 15 PSIG when

the pressure to the “H”

connection is .05 in. WG

greater than

the pressure to

the “L” connection. The

output at zero differential is

9 PSIG (63 kPa).

Installation The P-5215 Differential Pressure Transmitter is factory calibrated in the vertical position; therefore, the unit MUST BE MOUNTED WITHIN 15 ANGULAR DEGREES OF THE VERTICAL POSITION as indicated in Fig. 4. Note: It is recommended that a level be used to obtain this vertical position. Refer to Table 3 for a list of items required to perform installation and commissioning.

Commissioning 4. Pre-Commissioning Setup 1. Loosen the two cover holding screws and remove the P-5215 cover. 2. Furnish 20 PSIG (140 kPa) supply air to the “S” connection. 3. Note: It is recommended that the P-5215 be allowed to settle out for approximately 24 hours before it can be commissioned. 5. Hook up a test divider circuit as shown in Fig. 5. 6.

Fig. 7: Differential Pressure vs Output Pressure 9. Noting the desired maximum differential pressure, determine the proper transmitter output from the graph in Fig. 7. Be sure to use the scale on the graph that matches the range of the transmitter. If 15 PSIG (105 kPa) has not been achieved, proceed to Step 10; if 15 PSIG has been achieved, proceed to Step 11. 10.
