SAFETY MESSAGES Procedures and instructions in this manual may require special

precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Refer to the safety messages listed at the beginning of each section before performing an operation preceded by this symbol.

Failure to follow these installation guidelines could result in death or serious injury.

• Make sure only qualified personnel perform the installation.

TRANSMITTER OVERVIEW Thank you for choosing the Model 244E. Features of the Model 244EH

and Model 244ER transmitters include:

• Configuration using the Model 244EC Configuration Interface and a Microsoft and 244ER Configuration Software

• The ability to convert RTD and thermocouple inputs to 4–20 mA, 2-wire outputs that are less susceptible to electrical noise

• The capability to linearize RTD and thermocouple inputs with temperature

• Electrical input-output isolation

• Electronics that are completely encapsulated in epoxy and enclosed in a metal housing, making the transmitter extremely durable and ensuring long-term reliability

• A compact size and two housing options allowing mounting flexibility for the control room or the field

Rosemount Inc. has a full range of compatible connection heads, sensors, and thermowells to provide complete assemblies for process temperature measurements. Refer to Volume 1 of the Rosemount Temperature Sensors and Assemblies Product Data Sheet (document number 00813-0100-2654) for thread mount sensors and accessories, or refer to Volume 2 (document number 00813-0100-2654) for DIN-style sensors and accessories.

CONSIDERATIONS General Electrical temperature sensors such as RTDs and thermocouples

produce low-level signals proportional to their sensed temperature. The Models 244EH and 244ER transmitters convert the low-level sensor signal to a standard 4–20 mA dc signal that is relatively insensitive to lead length and electrical noise. This current signal is then transmitted to the control room via two wires.

Mechanical When choosing an installation location and position, take into account

the need for access to the transmitter.

Wiring Connections

Make wiring connections through the cable entry in the side of the connection head. Be sure to provide adequate clearance for cover removal.

Electrical Proper electrical installation is necessary to prevent errors due to

sensor lead resistances and electrical noise. Shielded cable should be used in electrically noisy environments.

Environmental The transmitter electronics module is permanently sealed within the

housing, resisting moisture and corrosive damage. Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.

SAFETY MESSAGES Instructions and procedures in this section may require special

precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol.

Warnings

Explosions could result in death or serious injury.

• Do not remove the enclosure cover in explosive atmospheres when the circuit is live.

• Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certification.

• Enclosure covers must be fully engaged to meet explosion-proof requirements.

Process leaks could result in death or serious injury.

• Installand tighten thermowellsor sensors before applying pressure, or process leakage may result.

• Do not remove the thermowell while in operation. Doing so may cause process fluid leaks.

Electrical shock could cause death or serious injury.

• If the sensor is installed in a high-voltage environment and a fault condition or installation error occurs, high voltage may be present on transmitter leads and terminals.

• Use extreme caution when making contact with leads and terminals.

MOUNTING The Model 244EH installs in a connection head or universal head

mounted directly on a sensor assembly, apart from a sensor assembly using a universal head, or to a DIN rail using an optional mounting clip. The Model 244ER mounts directly to a wall or to a DIN rail.

The Models 244EH and 244ER transmitters will operate within specifications for ambient temperatures between –40 and 185 °F (–40 and 85 °C).

In a direct mounting configuration using a Model 244EH transmitter, process heat is transferred from the thermowell to the transmitter via the connection head. If the expected connection head temperature is near or beyond specification limits, consider the use of additional thermowell lagging, an extension nipple, or a remote mounting configuration to isolate the transmitter from excessive temperatures. Figure 2-2 provides an example of the relationship between transmitter housing temperature rise and extension length. Use Figure 2-2 as a guide for determining adequate thermowell extension length.

Extension Length (mm)

3044-0123A

Example

The transmitter specification limit is 85 °C. If the ambient temperature is 55 °C and the process temperature to be measured is 800 °C, the maximum permissible connection head temperature rise is the transmitter specification limit minus the ambient temperature (85 –55 °C), or 30 °C. In this case, an extension of 100 mm meets this requirement, but 125 mm provides a margin of 8 °C, thereby reducing any temperature effects in the transmitter.

Figure 2-9. Multichannel Installations

Multichannel Installations

Several transmitters can be connected to a single master power supply as shown in Figure 2-9. In this case, the system may be grounded only at the negative power supply terminal. In multichannel installations where several transmitters depend on one power supply and the loss of all transmitters would cause operational problems, consider a back-up battery or power supply that cannot be interrupted. The diodes shown in Figure 2-9 prevent unwanted charging or discharging of the back-up battery.
