To mount any of the devices except Case 371–07/08 and

867E) to a flat surface such as a circuit board, the spacing and

diameter for the mounting holes should be made according to

Figure 3.

Mounting Screws

Mounting screws are recommended for making a very

secure, yet removable connection. The screws can be either

metal or nylon, depending on the application. The holes are

0.155

″ diameter which fits a #6 machine screw. The screw can

be threaded directly into the base mounting surface or go

through the base and use a flat washer and nut (on a circuit

board) to secure to the device.

MOUNTING TORQUE

The torque specifications are very important. The sensor

package should not be over tightened because it can crack,

causing the sensor to leak. The recommended torque

specification for the sensor packages are as follows:

Port Style

Torque Range

Single side port:

port side down

port side up

Differential port (dual port)

Axial side port

3–4 in –lb

6–7 in –lb

9 – 10 in – lb

The torque range is based on installation at room

temperature. Since the sensor thermoplastic material has a

higher TCE (temperature coefficient of expansion) than

common metals, the torque will increase as temperature

increases. Therefore, if the device will be subjected to very low

temperatures, the torque may need to be increased slightly. If

a precision torque wrench is not available, these torques all

work out to be roughly 1/2 of a turn past “finger tight” (contact)

at room temperature.

Tightening beyond these recommendations may damage

the package, or affect the performance of the device.
