Installation

INSTALLATION

PROCEDURE

Installation consists of mounting the transmitter and sensor assembly and

making electrical connections. If mounting the transmitter directly to the sensor

assembly, use the process mounting technique shown in Figure 2-1 or Figure 2-2,

on page 2-3. For transmitter locations remote from the sensor, use conduit

between the sensor and transmitter. Transmitter hubs will accept male conduit

fittings with ½–14 NPT; ½–14 NPSM; or ½–14 taper thread per ANSIC 80.4.

Mechanical 1. Mount the thermowell t o the pipe or process container wall.

2. Attach any necessary extension nipples and adapters. Seal the nipple and

adapter threads with silicone or tape.

3. Screw th e sensor into the thermowell.

4. Install drain seals if required for severe environments or to satisfy code

requirements (See Figure 2-2 on page 2-3).

5. Attach the transmitter to the thermowell assembly. Seal the adapter

threads with silicone or tape.

6. Install conduit for field wiring to the remaining conduit entry of the

transmitter. Seal conduit threads with silicone or tape.

7. Pull fie ld wiring leads through the conduit into the terminal side of the

transmitter housing.

Electrical

Explosion may result in death or serious injury. Do not

remove theinstr umentc overin explosive atmospheres

when the circuit is alive.

High voltagetha t maybe present on leads may cause

electrical shock. Avoidcontact with the leads and the

terminals.

Process leaks may result in deathor se rious injury.Install

and tighten thermowells or sensors beforeapplying

pressure, or process leakage may result.Removing the

thermowell or sensor while in operationmay cause process

fluid leaks.

Forexplosion-proof installations, wiring connections must

be made in accordance with Rosemount drawing00444-

0261, Rev.E.

Forintr insicallysafe installations, wiring connections must

be made in accordance with ANSI/ISA-RP12.6, and

Rosemount drawing 00444-0034, Rev.C (CSA) or 00444-

0264, Rev.B (SAA).

Forall installations, wiring connections must followthe

National Electric Code.
