Alberta Boilers Safety Association (ABSA) Practice Test

Which statement is true regarding smart transmitters?

1. They can only transmit in analog format

2. They can transmit both analog and digital signals

3. They require manual calibration at all times

4. They are incapable of remote zeroing

The correct answer is: They can transmit both analog and digital signals

Smart transmitters are advanced devices designed to measure and transmit process variables such as pressure, temperature, or flow. The correct statement indicates that these transmitters have the capability to transmit both analog and digital signals. This dual capability is crucial because it allows smart transmitters to integrate seamlessly with modern control systems and data communication networks. The digital signals facilitate more sophisticated data handling, such as diagnostic information, improved accuracy, and remote configuration capabilities, which are not possible with traditional analog transmitters. Furthermore, the assertion that they can transmit only in analog format, require manual calibration at all times, or are incapable of remote zeroing does not reflect the functionalities of smart transmitters. They typically allow for various calibration options, including remote zeroing, and their intelligent design supports a range of communication protocols beyond analog signals. Ultimately, recognizing the versatility and advanced features of smart transmitters is essential for effective process control and monitoring.
