P7640U Differential Pressure Sensors

APPLICATION

The P7640U Universal Differential Pressure Sensors 
provide reliable, accurate measurement and control. 
Proper applications include measurement of extremely 
low pressure applications such as: building/room 
pressure, air flow, variable air volume, filter status, and 
duct pressure. They are ideal for clean rooms, hospitals, 
fume hoods, and computer rooms.

The P7640 Pressure Sensors are designed with field-
selectable 4-20 mA, 0-5 Vdc, or 0-10 Vdc output. The 
pressure ranges fall between 0–10 in. w.c./0–2500 Pa. 
See Table 2.

Accessory

32003169-001 Duct Pressure Pick-up Probe, 4 in.

INSTALLATION

When Installing this Product...

1.

Read these instructions carefully. Failure to follow 
them could damage the product or cause a hazard-
ous condition.

2.

Check ratings given in instructions and on the 
product to ensure the product is suitable for your 
application.

3.

Installer must be a trained, experienced service 
technician.

4.

After installation is complete, check out product 
operation as provided in these instructions.

IMPORTANT

All wiring must agree with applicable codes, 
ordinances and regulations.

Mounting

Screw holes are accessed inside the enclosure (with the 
cover removed) and are located in the upper left and 
lower right corners.

Panel Mount

Run tubing from one (static) or both (differential) barb 
fittings, making sure the typically higher pressure source 
is connected to the port labeled HI, and the typically 
lower pressure source is connected to the port labeled 
LO.

Configure the internal tubing as shown in Fig. 1. Use 
small diameter tubing for panel mount configuration.

Duct Mount

1.

Thread probe into the back of the housing.

2.

Configure internal tubing as shown in Fig. 2. Use 
large diameter tubing for duct mounting
configuration.

3.

Unit is typically mounted at the high pressure loca-
tion when used for differential control.

CONFIGURATION

Select the proper output, mode, and pressure range 
using the switches and jumpers:

1.

Select output using the output switch:
a. Current: mA (then skip to step 3), or
b. Voltage: Volt.

2.

Select 0-10 Vdc or 0-5 Vdc using jumper J4.

3.

Select bi- or uni-directional mode using jumper J5.

NOTE: Setting for 0 to 10 in. w.c. and bi-direc-

tional will give output from -10 to 10 in. 
w.c.

4.

Select inches w.c. or Pascal scale using jumper J7.

5.

Select fast or standard response time using jumper 
J8.

6.

Select appropriate full-scale pressure range using 
the rotary switch. Align arrow (not the slot) to the 
desired range. See Table 2 for the range selection 
guide.

NOTE: The universal model is marked full scale. 

When the range is changed, the LCD 
models momentarily indicate selected 
range.

7.

Set output according to Table 1.
