2.6 Process connection

The low side pressure port (atmospheric reference) on the process pressure gauge is

located in the neck of the device behind the housing. The vent path is between the housing

and sensor. (See Figure 2-3.)

2.7 Rosemount manifolds

The Rosemount 306 Integral Manifold mounts directly to the device. The manifold is used

with this device to provide block-and-bleed valve capabilities of up to 4000 psi (275 bar).

2.7.1 Installation procedure

The Rosemount 306 Manifold is for use only with a Rosemount Wireless Pressure Gauge.

Assemble the Rosemount 306 Manifold to the device with a thread sealant.

1. Place device into holding fixture.

2. Apply appropriate thread paste or tape to threaded instrument end of the

manifold.

3. Count total threads on the manifold before starting assembly.

4. Start turning the manifold by hand into the process connection on the device.

Interfering or blocking the atmospheric reference port will cause the device to output

erroneous pressure values.

Keep the vent path free of any obstruction, including but not limited to paint, dust, and

lubrication by mounting the device so the process can drain away.

Do not apply torque directly to the sensor module. Rotation between the sensor

module and the process connection can damage the electronics. To avoid damage,

apply torque only to the hex-shaped process connection.
