All industries are interested in improving their processes, whether in the area of quality, safety or cost reduction. The use of sensors to continually measure and monitor the process is growing as plant managers see the benefits of keeping manufacturing processes at the right temperatures, scraping less product due to break downs and using the least amount of energy possible. Each sensor has a specific function and each are equally important to achieve the overall goal of the perfect process.

NK Technologies makes a large selection of sensors to measure electrical parameters, including current, voltage and power. The majority of these sensors supply an analog signal in proportion to the measured value. These can be converted to Modbus RTU through our ADC product, but the data still must be delivered to a controller or data acquisition system. The RS485 output can be transmitted via wire, but in some applications this is not an option. With the WRT series radio transmitter, data can be communicated between transceivers and up to a maximum of 800 meters using multiple hops.

WRT Wireless Data Transmitter/Receiver

NK Technologies’ WRT radio unit can be configured as a master to accept several data sources or can be used to transmit the data from one source only. Each unit can be configured for channel frequency, network address and can also be set so multiple groups of transmitters can be used to cover more location data points. The transmitter is small and can be mounted on a wall or in an appropriate enclosure if the environmental conditions require the unit be protected. A non-metallic enclosure will allow the units to communicate without interference.

Configuring the transmitters is easily done in the field, and we highly recommend using three units to provide the best self-healing, self-forming wireless network possible. The 2.4 GHz (IEEE 802.15.4) operation provides a worry free data stream, insuring that your equipment is protected by providing all of the information you need and want.
