Yokogawa Electric Corporation developed an ISA100 Wireless-based field wireless vibration sensor with the ability to quickly update data and have a long battery life. This sensor will release in North America in January.

By providing real-time updates on vibration levels in plant facilities, this sensor helps users quickly detect equipment anomalies and enables predictive maintenance.

With a field wireless system, plant field devices and analyzers are able to communicate wirelessly with host-level monitoring and control systems. The rising need to improve productivity and enhance safety by collecting more data on plant operations is driving the demand for field wireless devices, which can be installed even in difficult to access locations. Field wireless devices have the added advantage of reducing installation costs.

Vibration sensors are useful for the condition monitoring and predictive maintenance of plant machinery such as compressors, pumps, and motors. Conventional methods for monitoring vibration include the use of vibration sensors that rely on wired communications with a host system, and patrols by maintenance staff to collect vibration data. With the widening use of field wireless systems and the need to reduce installation costs, there is an increasing demand for wireless vibration sensors.

Since releasing its first ISA100 Wireless-based field wireless device and system, Yokogawa has expanded its lineup of field wireless devices that measure temperature, pressure, and flow rate. The sensor can provide quick updates on vibration levels needed to detect anomalies at an early stage.

The principal components of this field wireless vibration sensor are the FN510 field wireless multifunction module, the LN01 piezoelectric type acceleration sensor, and the FN110 field wireless communication module. Via a gateway device, the FN510 uses the ISA100 Wireless communications protocol to exchange data with a host-level system such as a DCS. The data collected with this vibration sensor enables plant operators and maintenance staff to monitor vibration levels in real time. Explosion proof and non-explosion proof types are available.

Key features of this sensor include:
1. Fast data updates: The sensor can be set to update data as quickly as every 10 seconds. This can end up used for monitoring vibration levels in plant facilities.

2. Long battery life and easy maintenance: When the vibration sensor is set to update data once per minute, it can operate on a single set of batteries for up to 10 years. In addition to eliminating the cost of providing replacement batteries, this reduces maintenance workload.

3. Highly reliable and versatile system: Thanks to the features of ISA100 Wireless there is a highly reliable wireless network with fully redundant communications capable of sending and receiving different types of sensor signals over long distances.
