Yokogawa announces the release of new pressure and temperature sensors for the Sushi Sensor wireless industrial IoT (IIoT) solution in Europe, North America, and specific Southeast Asian markets, with the release in other markets set to follow at a later date. These additions to the Sushi Sensor lineup, part of the OpreXTM Asset Management and Integrity family, were first released in Japan in July 2019. The new sensors facilitate the online collection of pressure and temperature data from equipment such as tanks and furnaces, and supplement the vibration and surface temperature monitoring capabilities of the integrated XS770A wireless vibration sensor launched in 2018. The expanded sensor lineup allows for equipment condition monitoring based on a wider variety of plant data. This in turn enables the reduction of equipment inspection man-hours and the detection of signs of equipment abnormalities at an early stage.

Longevity with Lorawan

As manufacturers strive to improve productivity and the efficiency of their plant maintenance operations, they have a growing need for solutions that facilitate the collection of equipment data. This is driving demand for wireless sensors that are easier and cheaper to install than conventional wired devices. In March 2018, Yokogawa released the integrated XS770A wireless vibration sensor to meet the need for an environmentally robust wireless sensor solution that can improve plant maintenance efficiency. The XS770A is a LoRaWAN® compliant equipment monitoring device with both vibration and surface temperature sensing capabilities. To meet its customers’ needs for solutions that can monitor equipment conditions based on a wider variety of measurement data, Yokogawa has now developed for the Sushi Sensor solution new pressure and temperature sensors that also support the LoRaWAN protocol. 

Yokogawa has developed the XS530 pressure measurement module, the XS550 temperature measurement module, and the XS110A wireless communication module. The new sensors are configured by attaching either the XS530 or the XS550 to the XS110A. The XS110A has a replaceable battery that can be easily accessed by removing the communication module from the pressure or temperature measurement module. The new modules all have an environmentally robust design, and are dustproof, waterproof (IP66/67 certified) and explosion-proof (ATEX and IECEx certified. Certification pending in North America). The battery life has also been extended to 10 years, based on an ambient temperature of 23° C +/-2° and an update interval of 1 hour. This reduces both the lifecycle cost and the frequency with which maintenance must be performed in often hazardous plant locations such as explosive environments or high places.

The XS530 pressure measurement module measures the gauge pressure (the pressure relative to atmospheric pressure) of gases and liquids in pipes and tanks. The wetted parts are all constructed of non-corrosive materials and the module is capable of withstanding high pressures. It has the high sensitivity necessary for low pressure measurements and can monitor both valve leakage and pipe/filter clogging. The XS550 temperature measurement module supports dual input from nine thermocouple types (B, E, J, K, N, R, S, T, and C) regulated by the IEC standard, and can measure both high and low temperatures. Data from the module can be used to identify the condition in each stage of a multistage heat exchanger, monitor the energy loss from steam leaks, and monitor the temperature inside tanks and on refractory bulkheads.

The devices target the markets of oil and gas, petrochemicals, chemicals, pulp and paper, pharmaceuticals, food as well as iron and steel, water supply and wastewater treatment. They can monitor pressure and temperature of equipment and devices such as heat exchangers, pumps, and tanks used in the above plants and the temperature of refractory bulkheads in furnaces.

Wireless IoT Solution

The Sushi Sensor Wireless Solution is a wireless solution that can detect signs of equipment abnormalities by storing the data from small vibration, temperature, and pressure sensors on an on-premises server or in the cloud. This solution helps customers maintain their plants and manage their energy use. Yokogawa also provides a cloud environment in addition to the Sushi Sensor wireless solution consisting of wireless sensors and wireless network devices.
