Technical Information

TI.264-04

PRESSURE TRANSDUCER

Inspect the package for damage. If damaged, notify the 
appropriate carrier immediately. If undamaged, open the 
package and inspect the device for obvious damage. 
Return damaged products.

Warning:

• 

Do not use on oxygen service, in an explosive/hazardous
environment, or with flammable/combustible media.

  Disconnect power supply before installation to prevent 

electrical shock and equipment damage.

  Make all connections in accordance with the job wiring diagram 

and in accordance with national and local electrical codes. Use 
copper conductors only.

Caution:

  Use electrostatic discharge precautions (e.g., use of wrist 

straps) during installation and wiring to prevent equipment 
damage.

  Avoid locations where severe shock or vibration, excessive 

moisture or corrosive fumes are present. NEMA Type 4 
housings are intended for outdoor use primarily to provide 
a degree of protection against wind-blown dust, rain, and 
hose-directed water.

  Do not exceed ratings of the device.

 Tools 

(

not provided

)

-  Digital Volt-ohm Meter (DVM)
-  Appropriate screwdriver for mounting screws
-  Appropriate drill and drill bit for mounting screws

 Appropriate 

accessories

  Two #8 self-tapping mounting screws (

not provided

)

  Training: Installer must be a qualified, experienced technician

Wiring

Use maximum 12 AWG wire for wiring terminals. Use copper or 
stainless steel tubing for the connection to the transducer.  Refer 
to 

Figures 1, 2, 3, 

for wiring information and 

Figures

The PR-264 must be mounted on a vertical surface with the 1/8" 
NPT connection pointed downward.  Refer to 

Figure 7

 for 

mounting dimensions.

1.  Remove the transducer cover using a Phillips head 

screwdriver.

2.  Select the mounting location.

3.  Mount transducer on a vertical surface with two #8 self-tapping 

screws 

(not provided)

.

4.  Pull wires through bottom of enclosure and make necessary 

connections.

5.  Replace the unit cover and make pneumatic connections.
