It’s time for Sushi... I

n order to detect signs of equipment abnormalities at an early stage and

prevent unexpected failures, frequent measurements of the vibration and surface temperature of plant equipment such as compressors, pumps and motors is needed, and this data needs to be monitored online. Although crucial equipment may already be continuously monitored by using wired sensors, there is an increasing need for wireless vibration and temperature sensors that can be installed easily and at a low cost. Originally launched in Japan, Yokogawa’s compact, wireless, Sushi Sensor has been developed to meet the demands. Designed to measure vibration and temperature, this uses LoRaWAN, a low-power wide-area (LPWA) wireless data communication protocol that is attracting considerable interest among developers for use in IIoT applications. LPWA is a wireless communications technology which is optimised for long-distance communications and low-power consumption. LoRaWAN, an LPWA protocol that is based on an open standard, is promoted by the LoRa Alliance of more than 500 IoT companies and users worldwide. Yokogawa also offers field wireless systems that comply with the proven and highly reliable ISA100 Wireless standard and help to ensure stable and safe plant operations. This wireless networking technology is based on the ISA100.11a wireless communication standard for industrial automation that was developed by the International Society of Automation (ISA).

SENSOR FEATURES As the new sensor complies with the LoRaWAN communication standard for long-distance communications, it needs no repeaters. Battery-powered, compact and lightweight, this sensor can be mounted easily on all kinds of plant equipment, the company explains. In addition, the sensor supports

near-field radio communication (NFC), which allows sensor setting and condition monitoring from a smartphone via a dedicated app. This technology is suitable for short-range communications, over a distance of several centimeters,


The growth in demand for technologies that enable the collection of equipment data is driving the need for wireless sensors. In response, Yokogawa has introduced a new solution: the Sushi Sensor

enabling quick data exchange. The Sushi Sensor is also environmentally

robust and is suitable for installation in harsh plant locations. Data collected can be monitored either from an on-premise server or a cloud server via a LoRaWAN gateway. From the on-premise server, or any device in a remote location that can access the cloud server, operators and maintenance staff can monitor the vibration and surface temperature of equipment throughout a plant. Designed for such applications

as measuring the vibration and temperature of plant equipment such as compressors, pumps, motors, fans, and conveyors, the Sushi Sensor is suitable for use in a range of fields:

from oil and gas, petrochemicals, chemicals, electric power, pulp and paper, and pharmaceuticals, to food, iron and steel, water supply and wastewater treatment, metal, etc.

Inductive sensors from Contrinex have been selected for a range of Swiss-manufactured multi-purpose off-road tractors that allow the driver to choose between two-wheel or four-wheel steering. With the tractor, reliable operation all year round, on all types of terrain and in all weather conditions, is

essential as typical tasks include bulk-load transportation and agricultural engineering. Extreme conditions often demand increased manoeuvrability, so for maximum control the driver can engage four-wheel steering when required. When reverting to the default two-wheel steering configuration, the rear axle must be locked in the straight-ahead position to prevent misalignment of the rear wheels. Here, a rugged, reliable and accurate sensor system was needed to detect the straight-ahead position of the rear axle before it is locked. The sensor, however, needed to be capable of withstanding significant mechanical shock and vibration, while also being impervious to water ingress and suitable for extremes of temperature. Meeting the demands, inductive sensors from the Contrinex ‘Basic’ range have a V2A/AISI 303 stainless-steel body and vacuum-encapsulated electronics, and are rated for operation at temperatures between -25˚C and 70˚C. In this application, a narrow flange is attached to each end of the vehicle’s hydraulic power-steering rack. The sensor is mounted immediately below one end of the rack and detects the position of the flange as it passes over the sensing face. The sensing distance of 2mm eliminates any possibility of accidental collision with the flange. Configured with an industry-standard

PNP normally-open interface, the sensor features an integral M8 connector and connects to the vehicle’s central controller via a flexible PVC-sheathed cable. Adding the sensor requires minimal modification to the vehicle’s control systems, and maintenance is simple and fast. The chosen sensor detects the

straight-ahead position of the vehicle’s rear axle repeatably and accurately, ensuring correct, reliable, engagement of two-wheel steering.
