Monitoring for automation by Hansford Sensors
30/09/2013 Hansford Sensors Ltd
There are two main types of accelerometer: AC accelerometers and 4-20mA accelerometers. AC accelerometers are typically used with data collectors for monitoring the condition of more critical/complex machines, such as gearboxes and turbines, while 4-20mA components are commonly used with PLCs to measure lower value assets, such as motors, fans and pumps.Handheld vibration meters and data collectors are now commonplace, providing a line of defence when permanent online vibration instrumentation cannot be economically justified, or supplying a 'second opinion' when online systems are in place but, for example, the decision to stop the process is critical. The more critical the machinery in terms of safety and/or plant profitability, the more likely it is that a permanent online system will be employed.
A range of sensors and monitoring techniques are now available with which to maximise machine uptime by extending operating life beyond recommended maintenance intervals and, at the opposite end of the scale, identifying rapid increases in vibration that could lead to a catastrophic failure. The efficiency of vibration sensors has driven demand in a number of ways; as well as offering enhanced efficiency and increased performance, these devices also enable operators to satisfy the ever-more robust regulations imposed regarding health and safety, which have made the use of sensors in non-safe areas a prime requisite.
A range of sensors with different capabilities are now available to suit a variety of applications. For example, Hansford Sensors has launched the HS-109 triaxial accelerometer, enabling three axes to be read simultaneously, which reduces measurement time. Protected by a stainless steel casing, the HS-109 has an operating temperature range of -55 to 140 ºC and is sealed to give an ingress protection level of IP67.
Automation has the potential to boost productivity and efficiency, not to mention product quality, but it can only do so if the plant is adequately monitored and protected. Given the current economic climate, the challenges faced by manufacturers in 2012 - especially the pressures on operating costs - look set to continue for the foreseeable future, so an effective maintenance strategy is critical.
