Safety messages
NOTICE
This guide provides basic guidelines for Rosemount™ 214A2A Sensor models.Complications can arise if sensors are assembled to transmitters that have different, but compatible approval option codes. Be aware of the following situations:
- If an I.S. approved 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
WARNINGExplosions
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.
Conduit/cable entriesUnless marked, the conduit/cable entries in the housing use a ½14 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 accessUnauthorized 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.

NoteTo 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.

March 2021 Quick Start Guide
IIC or Ex ib IIC of the assembly is determined by the level of protection of the transmitter. The equipment category is 2 G.
During installation the proper cable and cable gland should be used, mounted in the conduit (M20, ½-in., ¾-in., etc.).
Special Conditions for Safe Use:
- Ambient temperature range of sensor assembly with PTFE cable insulation: -40 to +75 °C, and for Silicon cable insulation: -25 to +75 °C.

- The highest minimum ambient temperature as mentioned above and as mentioned on the transmitter, is decisive. The maximum ambient temperature (Tamax) is +80 °C.
- The maximum ambient temperature of the assembly is +75 °C or the maximum ambient temperature as mentioned on the transmitter -10 K, which ever is smaller.
3. When the process temperature range exceeds the specified ambient temperature range, it shall be verified by on-site temperature measurements, taking the worst case conditions into account, that the service temperature of the connection head and the connection box does not exceed the ambient temperature range. The measurement report with the conclusions shall be filed together with the certificate to prove that this condition is met.4. From a safety point of view,
- The thermocouple inserts with a nominal tip diameter less than 3.0 mm,
