Semaphore Announces Extended Temperature Range Operation for High Performance RTU

LAKE MARY, FL--(Marketwired - Jan 23, 2014) -  Semaphore, a Servelec Group Company, announces successful, extended-range operating temperature testing for the TBox LT2 High Performance Remote Terminal Unit (RTU). During factory testing, TBox LT2 continued to operate at an ambient temperature of -55 degrees Celsius (C), significantly better than the current warranted temperature range.

While most RTU products operate at temperatures as low as -40 degrees C, performance cannot be guaranteed beyond that point. Operation ceases or becomes undefined. The wider temperature range is particularly advantageous for oil & gas installations in northern latitudes, where the ambient temperature can be well below -40 degrees.

TBox LT2 is an all-in-one SCADA system featuring integral web server, 3G wireless communications, and a complete cyber security application suite, all tightly integrated with programmable automation, alarm notification, data logging and Ethernet communications in a single, rugged module. The platform leverages instant notification via e-mail, SMS text and FTP but also provides traditional, SCADA communications for gas measurement using the Enron Modbus protocol.

When used in conjunction with Semaphore's TFlo gas flow measurement software, TBox LT2 provides a flow computing solution that meets or exceeds Alberta Energy Regulator (AER) Directive 17 and American Petroleum Institute (API) Chapter 21.1 requirements. TBox LT2 is also approved for installation in Class I, Division 2, Groups A - D hazardous areas.

Device-agnostic Web pages make information available to users anytime, anywhere with connectivity to virtually any mobile device. In addition, with Semaphore's WebForm™ Studio 2.0 Webserver, users can quickly customize Web pages to meet specific requirements. No coding or programming is required.
