1 About this guide

This guide provides basic guidelines for Rosemount 214C Sensor models. If

the sensor was ordered assembled to a temperature thermowell or

transmitter, see the appropriate product literature for information on

configuration and hazardous locations certifications.

1.1 Safety messages

NOTICE

Complications can arise when the sensors and the transmitters to which they

are assembled are certified to compatible, but each has different approvals.

Be aware of the following situations:

•If an I.S. approved Rosemount 214C Sensor is ordered with a housing, a

transmitter enclosed in that housing may have a different I.S. approval

rating. Refer to the transmitter IS certificate if applicable.

•If a sensor and transmitter have different certifications, or if either has

more certifications than the other, installation must comply with the

most restrictive requirements required by either component. This is

especially (but not exclusively) relevant when combination approvals are

ordered on either the sensor or transmitter. Review certifications on

both the sensor and transmitter for installation requirements and ensure

installation of the sensor/transmitter assembly complies with a single

certification that is shared by both of these components and that meets

the requirements of the application.

WARNING

Explosion

Explosions could result in death or serious injury.

Installation of sensor in an explosive environment must be in accordance

with appropriate local, national, and international standards, codes, and

practices.

Quick Start Guide 3

WARNING

Conduit/cable entries

Unless marked, the conduit/cable entries in the housing use a ½–14 NPT

thread form. Entries marked “M20” are M20 × 1.5 thread form. On

devices with multiple conduit entries, all entries will have the same

thread form. Only use plugs, adapters, glands, or conduit with a

compatible thread form when closing these entries.

When installing in a hazardous location, use only appropriately listed or

Ex certified plugs, glands, or adapters in cable/conduit entries.

Only use plugs, adapters, glands, or conduit with a compatible thread

form when closing these entries.

Physical access

Unauthorized personnel may potentially cause significant damage to and/or

misconfiguration of end users’ equipment. This could be intentional or

unintentional and needs to be protected against.

Physical security is an important part of any security program and

fundamental to protecting your system. Restrict physical access by

unauthorized personnel to protect end users’ assets. This is true for all

systems used within the facility.

CAUTION

Refer to Product Certification section of this Quick Start Guide

documentation.

Note

To configure a single element, 4-wire RTD as a 3-wire system, connect only

one white lead. Insulate or terminate the unused white lead in a manner that

prevents shorting to the ground. To configure a single element, 4-wire RTD

as a 2-wire system, connect matching colored wires first and then connect

the paired wires to the terminal.
