Application examples
An RTD or thermocouple sensor with transmitter in remote installation, e.g. head transmitter in field housing
or DIN rail transmitter
Installed head transmitter - 1 x RTD/TC wired directly

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 one measuring input and one analog output.
The device not only transmits converted signals from resistance thermometers and thermocouples, italso transmits resistance and voltage signals using a 4 to 20 mA current signal. It can be installed as
an intrinsically safe apparatus in hazardous areas and is used for instrumentation purposes in theflat-face terminal head as per DIN EN 50446 or as a DIN rail device for installation in the cabinet on
a TH35 mounting rail as per EN 60715.
Intuitive commissioning and operation - wireless access to all device data via Bluetooth using the
SmartBlue app.

Standard diagnostic functions• Cable open-circuit, short-circuit of sensor wires• Incorrect wiring• Internal device errors• Overrange/underrange detection• Device temperature overrange/underrange detection
Corrosion detection as per NAMUR NE89
Corrosion of the sensor connection cables can cause incorrect measured value readings. The
transmitter makes it possible to detect corrosion of the thermocouples and mV transmitters, as well
as resistance thermometers and ohmmeters with 4-wire connection, before a measured value iscorrupted. The transmitter prevents incorrect measured values from being read out and can issue awarning if conductor resistance values 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 approx. 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.
Diagnostics simulation
Device diagnostics can be simulated. The following items are set during such simulations:• Measured value status• Current diagnostics information• Current output value as per simulated diagnostics
This simulation makes it possible to check that all higher-level systems respond as expected.

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.

deviation may occur depending on the installation situation and ambient conditions. If the DIN rail
device is mounted on the DIN rail without any adjacent devices, this may result in deviations of13

Operability
Local 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. 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 measurement chain, this will be
displayed in inverse color showing the channel ident and error number. DIP switches can be found on
the rear of the display. These enable hardware settings to be made e.g. write protection.

RN22

Single- or two-channel active barrier for safe separation of 0/4 to 20 mA standard
signal circuits with 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; the outputs can be operated
actively or passively. The RN22 requires a supply voltage of 24 VDC.

The Advanced Data Manager Memograph M is a flexible and powerful system fororganizing process values. Optional HART® input cards are available, eachproviding four inputs (4/8/12/16/20). They transmit highly accurate process
values from the directly connected HART® devices, so that they are available forcalculation and data 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 and calculated values can be very
easily communicated to higher-level systems or individual plant modules can beinterconnected.
