Differences

Performance

Significant improvements in smart transmitter accuracy, static pressure effects, temperature performance, and time stability provide a complete improvement in performance.

Rangeability

The power switch is increased to 400: 1 with a smart transmitter against a standard transmitter from 6: 1

The most noticeable variation helps to

1. Reduce the cost of backup management,
2. Increase the transfer of transmission equipment through crop rotation, too
3. It offers other benefits such as the freedom to define the distances directly when ordering units.
   A clear example of real savings with increasing variability is in applications where two or more standard units are used on a single orifice plate to improve the accuracy of various flows.

The difference in durability of intelligent transmission means that only one unit is required, thus only the other units and the cost of installing and maintaining them can be maintained and also prevent the low reliability that occurs in two or three loops against each other. In the case of a smart transmitter, the range can be changed manually using the speaker for various plant operating conditions.

Remote control adjustment

The range of the smart transmitter, water drain, etc., can now be adjusted from 1500 m away by contact over the 4-20 mA signal line. Adjustments can be made by connecting a smart field communicator (SFC) to all two signal lines at any location in their path.

1. The output can be seen as a straight or square root
2. The reduction time can be changed in several steps
3. LRV / URV can be adjusted to any value in the pressure range.
   Adjustments are made to any engineering units that can be selected in PSI, m bar, bar, k Pa.

Redesigning the smart transmitter without applying pressure is possible. Measurement corrections can be made with minor errors caused by ascending angle effects. Zero testing, and adjustments if necessary, can be done from the control room where the plants are closed or during regular maintenance. Remote diagnoses and remote control can now be performed back in the control room, thus taking a fraction of the previous maintenance period that usually requires two men several hours to do any field testing or switch.

All of the above can be done by one man from easily in the middle.

Reliability

The main purpose of intelligent transfer is built on reliable and stable work as a prerequisite. Few materials are used, and protection is provided against harmful influences, such as reverse polarity, over-pressure, and high voltage.

The SMART transmitter represents a Single Modular Auto-based Remote Transducer.

It is a smart transmitter with analog effect and simultaneously provides digital communication signal in accordance with the HART protocol or FOUNDATION FIELDBUS or PROFIBUS. Typically, a simplified drawing of a smart transfer is shown in the image below. Contains sensor or input circuits, microprocessor, memory, and communication block.

The term multi-variable transmitter is sometimes used especially in a device like a smart flow measurement tool. This measures the total pressure, power difference, and temperature process. It calculates the average flow rate and the volumetric flow rate of a liquid process.

SMART Transmitter

The result from the smart transmitter is no longer the same as the main variable process, but also includes secondary process variables, sensor health, sensory performance features, measurement power details, and real-time diagnosis. (This data can be accessed through the HART protocol or through fieldbus communication)

All of this information is used to improve the process, improve the performance of the metal while extending its life span, and increase productivity of workers. With the advent of the Internet, high data speeds, and with these smart tools and field systems are being transformed into part of the IoT (Internet of Things).

Advantages of SMART Transmitters

Below are a few advantages for Smart Transmitters:

1. Smart transmitters contain microprocessors and have bi-directional connections.
2. Smart transmitters include secondary sensors, which can measure and compensate for environmental disturbances.
3. Signal adjustment will be performed along with analog to digital conversion.
4. Smart Transmitters contain multiple sensors and cover various measurement distances and allow automatic selection of the required range.
5. Smart self-propelled transmitters allow for the removal of zero drift errors and sensitivity drift.
6. Smart transmitters will have the ability to self-test and one can set maintenance requirements.
7. It can adapt to offline lines and provide line output.
8. Smart transmitters provide improved accuracy and reliability.
9. Long-term stability can be improved, the frequency of re-balances can be reduced.
10. Reduced maintenance costs.
11. It allows interaction and is able to select your preferred vendors.
12. Allows remote remodeling and rearrangement.
13. Reduced in handling the number of inactive transmitters, because a single transmitter can be adjusted to cover any range and make it possible to replace transmitters.
14. Some transmitters such as the temperature gauge have a center for connecting unwanted sensors, which does not happen with standard transmitters. In the event of a failure of one sensor, the other sensor helps to detect heat that improves plant integrity.
15. Preparation data stored under the same tag can be transferred from handheld contacts or DCS programs.
16. Most smart senders have great power (two cables).

Disadvantages of SMART Transmitters.

As part of preventative maintenance, measurement or validation is unavoidable, although SMART senders.
