Suitable for use with any of this company’s range of explosion-proof, electrical heaters, the new generation Smart Controller 2.0 features fieldbus networking, extensive monitoring and diagnostic routines, programmable temperature ramping, data logging and temperature monitoring with user-definable limits. The controller has a switching capacity of 10 A, enabling it to be used with explosion-proof heaters with power ratings as high as 2.3 kW, depending on the ambient and required enclosure temperatures and the heater supply voltage. The new PID (proportional-integral-derivative) controller provides a high level of accuracy and functionality. Operating as a remote terminal unit, it uses ModBus RTU communications protocol over an RS 485 serial network to facilitate integration with existing process control systems. — Intertec Instrumentation Inc., Sarnia, Ont., Canada
