Product Description

Product Description

The Rosemount 248 HART Protocol Temperature Transmitter Module Guide Rail Module 248HAI1N0NS is a high - performance device designed to meet the demands of various industrial applications.

High-Precision Measurement
This transmitter module has single sensor capability with universal sensor inputs. It can accept inputs from RTDs (Resistance Temperature Detectors), thermocouples, millivolts , and ohms. This versatility means that it can be used with a wide variety of temperature sensors, making it adaptable to different measurement requirements. For example, in a chemical processing plant, different parts of the process may require different types of sensors due to varying temperature ranges and environmental conditions. The Rosemount 248 with its universal inputs can handle all these sensor types without the need for multiple different transmitters.

Output Signal
The output signal of the 248HAI1N0NS is based on the 4 - 20 mA standard with a digital signal overlay using the HART protocol. The 4 - 20 mA analog signal is widely used in industrial applications for its simplicity and reliability in transmitting information over long distances. The HART protocol, on the other hand, allows for two - way digital communication. This enables the user to access additional information such as device diagnostics, calibration data, and configuration settings. For instance, a maintenance engineer can use a handheld HART® communicator to quickly check the status of the transmitter, adjust the calibration, or modify the measurement range without having to physically disconnect the device from the process.

 

Advanced Diagnostics
It comes with basic diagnostics including open/short sensor diagnostics. This feature is crucial for ensuring reliable performance. By continuously monitoring the sensor loop, the transmitter can quickly detect if there is an open circuit (which could be due to a broken wire) or a short circuit in the sensor. In case of such an issue, the transmitter can send an alert to the control system, allowing maintenance personnel to take immediate action. This helps to prevent incorrect temperature readings and potential process disruptions, ultimately improving the overall efficiency and safety of the industrial process.
