YTMX580, built on the ISA100.11a wireless standard, is a battery-powered temperature transmitter with an eight-analog input channel. Each input is configurable for thermocouple, RTD, DCV and 4-20mA measurement. The intrinsically safe battery pack, designed for field replacement in hazardous areas, uses two D-size, 3.6-V, long-life, lithium-thionyl chloride batteries.
