Retrofittable Valve Sensor ATEX zone 1 / IECEx

Add-on intelligence that increases insight, safety and avoids spillage for industrial valves

Having reliable information available is the essence of good decision making to ensure safety in working environments, especially in industrial sites. As a result, businesses will run more efficiently and operations will be streamlined. TWTG’s Industrial IoT-connected valves provide this insight.

Manually operated valves require to be regularly checked and controlled which can be facilitated by digitisation. Monitoring these assets will avoid spillage and / or contaminations, and thus increase safety on-site. Com-munications via a privately hosted LoRa WAN – IoT network ensures IT security is a given and the total cost of ownership can be minimised. As valves are most often operated in environments with explosive atmospheres, all TWTG valve sensors are ATEX zone 1 / IECEx certified.

Works with all types of valves, without replacing them.

ATEX certified – built to last

Designed for industry from the very start, TWTG’s Valve Sensors are built to not only operate in industrial sites with dangers of explosive gases being handled but also all other elements that a sensor may be exposed to in the course of its 15 year lifetime. It has been tested and certified to work in conditions from -40 to +80 degrees Celsius without hampering performance. Additionally, the battery lifetime has a minimum operational period of 3 years, hence, periodical maintenance can be kept at a minimum. An integrated device management layer provides remote software updates, to prolong the usability and lifetime.

Low cost and quick installation plus tailor made for large deployment

Reliability is the first thing to consider when providing insight based on new technologies. Therefore, our Valve Sensors have been specifically designed to only communicate the essential: closed or open. This allows our customers to reduce false positives immensely and be certain of the measurements the sensor delivers. The sensors communicate via a privately hosted LoRa WAN network, with gateways tailor made for the same industrial conditions and requirements of the Valve Sensor (globally). TWTG installs this network and it has been designed to scale up in numbers and for other I-IoT solutions in the future. Furthermore, they can be integrated with DCS / SCADA systems to ensure operational excellence.
