Sushi sensor comes to Europe

04 February 2019

Yokogawa Electric Corporation has announced that it will release its Sushi Sensor, an OpreX brand wireless solution in Europe.

The Sushi Sensor is a compact wireless device with integrated sensing and communication functions that is designed to monitor plant equipment vibration and surface temperature. Optimised for IIoT applications, the sensor is said to enable the online monitoring of equipment operating conditions, which helps to improve equipment maintenance and prevent failures by detecting signs of abnormalities at an early stage.

To detect signs of equipment abnormalities at an early stage and prevent unexpected equipment failures, it is essential to frequently measure the vibration and surface temperature of plant equipment such as compressors, pumps, and motors, and to enable the monitoring of such data online. Although crucial equipment may already be continuously monitored by using wired sensors, this may be difficult with many other types of equipment due to the high initial cost and the challenges of wiring devices in difficult to access locations. Such equipment must be inspected during operator rounds or periodic inspections. Therefore, there is an increasing need for wireless vibration and temperature sensors that can be installed easily and at a low cost, to improve maintenance efficiency.

The Sushi Sensor meets this need, offering a compact wireless device that measures vibration and temperature and uses LoRaWAN, a low-power wide-area (LPWA) wireless data communication protocol that is optimised for long-distance communications and low-power consumption. LoRaWAN, an LPWA protocol based on an open standard, is promoted by the LoRa Alliance of more than 500 IoT companies and users worldwide.

The compact wireless Sushi Sensor complies with the LoRaWAN communication standard for long-distance communications, so needs no repeaters. It is also battery-powered, eliminating the need for an external power supply. Being compact and light-weight, this sensor can be mounted easily on all kinds of plant equipment. In addition, the sensor supports near-field radio communication (NFC), which allows sensor setting and sensor condition monitoring from a smartphone via a dedicated app. This technology is suitable for short-range communications, over a distance of several centimeters, enabling quick data exchange.

The sensor is environmentally robust and is well suited for installation in harsh plant locations.
