Installation

Step 3

Mounting

Mounting any D or DT sensor

CAUTION

Using the sensor to support piping
can damage the sensor or
cause measurement error.

Do not use sensor to support pipe.

Keys for sensor mounting

Use your common piping practices to minimize:
• Torque on process connections
• Bending load on process connections

•

For proper orientation, see pages 14-16

•

For optional D600 mounting, see page 18
