Application examples
Two sensors with measuring input (RTD or TC) in remote installation with the following advantages: drift
warning, sensor backup function and temperature-dependent sensor switching
Integrated transmitter - 1 x RTD/TC or 2 x RTD/TC for redundancy

Endress+Hauser offers a comprehensive range of industrial thermometers with resistance sensors or
thermocouples.
When combined with the temperature transmitter, these components form a complete measuring
point for a wide range of applications in the industrial sector.
The temperature transmitter is a 2-wire device with two measuring inputs and one analog output.
The device not only transfers converted signals from resistance thermometers and thermocouples, italso transfers resistance and voltage signals using HART communication and as a 4 to 20 mA
current signal. It can be installed as an intrinsically safe apparatus in hazardous areas. It is used for
instrumentation in the terminal head (flat face) as per DIN EN 50446, for installation in the cabinet
on a TH35 mounting rail as per EN 60715 or mounted in a 2-compartment field mount housing withglass window and included plug-on display.

Device architecture for HART communication

Endress+Hauser

iTEMP TMT82

Standard diagnostic functions• Cable open-circuit, short-circuit of sensor wires• Incorrect wiring• Internal device errors• Overrange/underrange detection• Ambient temperature out-of-range detection
Corrosion detection as per NAMUR NE89
Corrosion of the sensor connection cables can cause incorrect measured value readings. The
transmitter offers the possibility of detecting any corrosion of the thermocouples, voltage
transmitters (mV) and resistance thermometers, resistance transmitters (Ohm) with 4-wireconnection before a measured value is corrupted. The transmitter prevents incorrect measured
values from being exported and can issue a warning via the HART protocol if conductor resistancevalues exceed plausible limits.
Low voltage detection
The low voltage detection function prevents the device from continuously transmitting an incorrect
analog output value (caused by an incorrect or damaged power supply system or a damaged signal
cable). If the supply voltage drops below the required value, the analog output value drops to <3.6 mA for 5 s. The device then tries to output the normal analog output value again. If the supply
voltage is still too low, this process is repeated cyclically.
2-channel functions
These functions increase the reliability and availability of the process values:• Sensor backup switches to the second sensor if the primary sensor fails• Drift warning or alarm if the deviation between sensor 1 and sensor 2 is less than or greater thana predefined limit value• Temperature-dependent switching between sensors which are used in different measuring ranges• Mean value or differential measurement from two sensors• Mean value measurement with sensor redundancy
Not all modes are available in the SIL mode, see the 'Functional Safety Manual'.

In the case of 2-channel measurement the same measuring unit must be configured for the two channels (e.g. both °C or F or K). Independent 2channel measurement of a resistance transmitter (Ohm) and voltage transmitter (mV) is not possible.

Sensor input 1, thermocouple (TC)If sensor input thermocouple (TC) is selected: permanent connection of the external reference junction,
terminals 4, 5 and 6 (Pt100, IEC 60751, class B, 3-wire). It is not possible to connect a second thermocouple(TC) on sensor 2.

An unshielded installation cable suffices if only the analog signal is used. The use of shielded cables
is recommended for increased EMC interference. As of a sensor cable length of 30 m (98.4 ft)30 m(98.4 ft), a shielded cable must be used for a head transmitter in the field mount housing with aseparate terminal compartment and for the DIN rail transmitter.
A shielded cable is recommended for HART communication. Observe grounding concept of the plant.
A minimum load of 250 Ω is required in the signal circuit in order to operate the HART transmitter
via the HART protocol (terminals 1 and 2).

Sensor adjustment

Sensor-transmitter-matching
RTD sensors are one of the most linear temperature measuring elements. Nevertheless, the output
must be linearized. To significantly improve temperature measurement accuracy, the device allows
the use of two methods:• Callendar van Dusen coefficients (Pt100 resistance thermometer)
The Callendar van Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter in order toimprove the accuracy of the measuring system. The coefficients for a standard sensor are specified
in IEC 751. If no standard sensor is available or if greater accuracy is required, the coefficients foreach sensor can be determined specifically with the aid of sensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistance thermometers(RTD). The exact values of the coefficients derive from the calibration data and are specific to eachsensor. The sensor-specific coefficients are then sent to the transmitter.
Sensor-transmitter matching using one of the methods mentioned above significantly improves thetemperature measurement accuracy of the entire system. This is because the transmitter uses the
specific data pertaining to the connected sensor to calculate the measured temperature, instead ofusing the standardized sensor curve data.
1-point adjustment (offset)
Shifts the sensor value
2-point adjustment (sensor trimming)
Correction (slope and offset) of the measured sensor value at transmitter input

Current output adjustment

Correction of 4 or 20 mA current output value (not possible in SIL mode)

• DIN rail transmitter: When DIN rail transmitters are used with a thermocouple/mV measurement,
increased measurement deviation may occur depending on the installation situation and ambientconditions. If the transmitter is mounted in series in between other DIN rail devices (reference

To avoid additional higher measurement deviation, mount the DIN rail transmitter verticallyand ensure that it is correctly aligned (sensor connection at bottom / power supply at top).

Operability
Onsite operation

Head transmitter
The head transmitter has no display or operating elements. There is the option of using theattachable measured value display TID10 together with the head transmitter. When the headtransmitter will be ordered with the field mount housing with separate terminal compartment, thedisplay is already included. The display provides plain-text information on the current measured
value and the measuring point identification. An optional bar graph is also used. In the event of a
fault in the measuring chain, this will be displayed in inverse color showing the channel ident anderror number. DIP switches can be found on the rear of the display. These enable hardware settings
to be made e.g. write protection.

System components

RN22
Single- or two-channel active barrier for safe separation of 0/4 to 20 mA standard signal circuitswith bidirectional HART transmission. In the signal duplicator option, the input signal is transmitted
to two galvanically isolated outputs. The device has one active and one passive current input; theoutputs can be operated actively or passively. The RN22 requires a supply voltage of 24 VDC.
Technical Information TI01515K
RN42Single-channel active barrier for safe separation of 0/4 to 20 mA standard signal circuits withbidirectional HART transmission The device has one active and one passive current input; theoutputs can be operated actively or passively. The RN42 can be powered with a wide range voltage of
24 to 230 VAC/DC.
Technical Information TI01584K
RIA15
Process display, digital loop-powered display for 4 to 20 mA circuit, panel mounting, with optional
HART communication. Displays 4 to 20 mA or up to 4 HART process variables
Technical Information TI01043K
Advanced Data Manager Memograph M
The Advanced Data Manager Memograph M is a flexible and powerful system for organizing process
values. Optional HART input cards are available, each having 4 inputs (4/8/12/16/20), with highly
accurate process values from the HART devices directly connected for the purpose of calculation anddata logging. The measured process values are clearly presented on the display and logged safely,
monitored for limit values and analyzed. Via common communication protocols, the measured andcalculated values can be easily communicated to higher-level systems or individual plant modules
can be interconnected.
