Traditionally the paper industry is very well developed in applying vibration monitoring to oversee the health of the main machine and any ancillary equipment. Over a number of years Hansford Sensors has supplied many thousands of vibration sensors into this area of industry.
As a supplier of industrial accelerometers, one of the toughest challenges Hansford Sensors encounters is providing sensors which will withstand the harsh conditions that exist in a paper mill.
Specifying vibration diagnostics
Depending on the capital available, there are several approaches that can be applied to monitor the main machines. Online and offline readings are taken but either approach uses the same accelerometer connected back to a local junction box for an online system or switch/connection enclosures for the offline data collector.
Within the Hansford Sensors range of products, there are accelerometers that have been designed to suit the different conditions on a paper machine. In the wet areas, we would always use the standard AC sensors (HS-100 Series) with integrated silicon cable which has a sealing rating of IP68. These sensors can be supplied in top or side entry and are submersible.
For the press and dryer sections Hansford Sensors would recommend using an AC sensors with an integrated connector 2 Pin MS connector (HS-100 Series) either top or side entry depending on the headroom and costs. This accelerometer would require a separate mating cable assembly (HS-AC001) which can be supplied in several forms, the most popular being the silicon (HS-AC030) which is flexible, easy to install in conduit and when fitted to the accelerometer provides IP66 sealing.
Vibration monitoring equipment
There is a family of junction/switch/connection boxes that are available in a range of different materials including stainless steel, painted mild steel and polycarbonate housing. These boxes are available with a number of different channels to suit the machine application.
All of the sensors are available with a variety of different mounting studs including a quick fit option which enables the sensor to be easily removed from the machine during maintenance. Depending on the installation, other thread options are available including M6, M8 and ¼ UNF.
