Yokogawa Electric Corp. has developed a multi-protocol wireless adaptor that enables wired field instruments or analytical sensors to be used as ISA100 Wireless™ devices. The company will release models in May and July 2014 that support communications based on the HART® and RS485 Modbus standards. To facilitate the introduction of field wireless systems in plants, Yokogawa plans to release additional models that will cover other standards. When the multi-protocol wireless adaptor is mounted on a wired field instrument or analytical sensor, the instrument or sensor is able to function as an ISA100 Wireless device. It may be used with any type of wired field instrument or analytical sensor commonly used in plants, including those used to monitor temperature, pressure, liquid level or vibration or to detect gas and is compatible with both Yokogawa devices and devices from other vendors.
