Data Logger: The Need for Data Analysis
Steam quality is monitored by specialized equipment designed for that purpose. Please see below on understanding the need to monitor steam quality.
Even if the steam quality is within permissible limits or limits as defined by the user, it could still be non-ideal. The steam could still be slowly damaging your equipment. It is very important that you analyse the steam quality as it moves across your process chain.
Armstrong contracted Sosaley Technologies to develop a data logger that could talk to their steam quality monitoring device and log the data on a continuous basis. The objective was to gather the data from multiple points in the process chain and analyse the quality of steam as it moves from one point to another.
The Armstrong Steam Quality Monitoring Device
Armstrong has an advanced steam quality monitoring device (SQMD) that uses pressure, temperature and release to the atmosphere to measure the steam quality. If there is a problem, it raises an alarm for you to take action immediately. The various factors to measure the quality of steam are user definable. The Amstrong SQMD can be placed in one or more places across the process flow to monitor steam quality.
The Armstrong SQMD has an RS485 serial port. Using Modbus, you can monitor the quality of steam.
The Sosaley Data Logger
The Sosaley Data Logger connects to the RS-485 connection point of any steam quality monitoring device. It is a small device that has been designed to work in a harsh environment. It gathers all the data read by the SQMD and stores it in a local pen drive. At appropriate timings, the pen drive can be removed from the system to transfer the data to a PC.
The Sosaley Data Logger can be installed as a Master or a Slave in terms of communication. In the Master mode, the Sosaley Data Logger will ping the SQMD on a pre-defined time frequency and request for data transfer. As a slave, the Sosaley Data Logger will just listen all the time and log whatever data it receives from the SQMD.
The Sosaley Data Logger gets data in Hex format from the SQMD. Internally, it converts the data to textual format and stores the data as a delimited file.
Data Sampling Frequency
You can set the frequency at which data is to be captured anywhere between 5-1000 seconds.
