As the steel industry continues to strive for more effective plants with 100% availability, Hansford Sensors remains committed to helping customers monitor plant machinery effectively. Typical areas include rolling mills, drives, gearboxes and cooling towers.
Before getting too involved in what technique is to be applied, consideration needs to be taken to whether the application requires offline or online monitoring.
Within the Hansford Sensors range of products, the AC sensor (HS-100 Series) has been designed to withstand the harsh conditions that exist in the steel industry. There is also supporting hardware that can be used to connect to a local interface box (HS-SE) for offline readings using a data collector or permanently installed equipment (4-20 mA accelerometers, HS-420 Series) that can be connected to a PLC for trending and logging.
More sophisticated systems involve looking at velocity and bearing conditions. In this example, the standard AC sensors (HS-100 Series) connected back via a vibration module (HS-500 Series) can be used to protect the machine. When used with the vibration module (HS-510), the output can be displayed and alarmed locally and also connected back to the PLC. Wireless options are also available.
Within the Hansford range of accelerometer products there are a selection of different mountings and connection methods, including armoured, silicon and fire retardant styles. Consideration must also be made to the practicality of the installation and in areas where the machine may need to be accessed it is recommended that sensors with a separate cable assembly are used.
Optimise sludge treatment and reduce operational costs
Sensors & Transducers
The Endress+Hauser inline measuring devices, the Proline Teqwave MW 300 and the Proline Teqwave MW 500, determine the total solids content of wastewater directly through microwave transmission. This is considerably less time consuming than the process of determining total solids content in a laboratory.
