Yokogawa wireless instrument system

Yokogawa has released a range of wireless instruments including pressure, differential pressure and temperature sensors. They are designed to provide accurate transmission of data with virtual zero bit rate error up to 600 m, without the need for special antennas.

They also support multiple industrial protocols - HART, Profibus, Modbus and Foundation Fieldbus. The ISA100.11a standard employed in the Yokogawa wireless instruments talks to all other certified ISA100.11a devices. ISA100.11a is an end-user protocol, designed by end users for end users, which does not lock users into any proprietary protocol.

Yokogawa’s ISA100.11a wireless products provide unlimited networking capabilities using the IPv6 protocol, which supports an almost infinite number of addresses. This means there is no limit to the number of devices in a network.

Yokogawa’s pressure transmitters utilise its digital DPharp advanced silicon resonant sensor. This sensor uses two resonators embedded inside a silicon diaphragm to measure the applied pressure. It allows simultaneous wireless measurement of differential and static pressure.

The instruments are IECEx certified ‘intrinsically safe’ and include Yokogawa’s Integrated Gateway (YFGW) that functions as a backbone router, system manager, security manager and gateway with IECEx Type n certification.

The Yokogawa wireless instrument system is configured with Yokogawa’s Field Wireless Tools comprising the FieldMate Device Management & Provisioning Tool, Network Management Tool and Field Wireless Configurator.
