Auburn’s TRIBO.dsp U3400H is the industry’s first two-wire, loop-powered, wide dynamic range particulate monitor for both high- and low-temperature applications utilizing HART protocol. The TRIBO.dsp U3400H was awarded Hazardous Location Certification by CSA International, a leading provider of product testing and certification services. CSA tests products for national and international standards.
There has been an increase in the number of particulate monitoring applications that require hazardous location certification. More companies are concerned about explosive dusts or volatile gases. The U3400H can be used for Class I, Div. 1, Groups C, D; Class II, Div. 1, Groups E, F, and G; Class III; also Class I, Zone 0, Group IIB.
Simple to install and requiring no operator sensitivity adjustment, the unit is ideal for all emission monitoring and process flow applications where a continuous 4-20 mA signal is needed. The HART protocol adds even more functionality for the operator allowing bi-directional communication with the unit for remote access and control. The U3400H is designed to be wired directly to a PLC, DCS, data loggers, or any control device capable of providing the 24V loop power, while simultaneously receiving the continuous 4-20 mA signal. The 3400H is ideal for multiple point applications needing a comprehensive bag leak detection system.
As dust particles collide with, or closely pass by a probe, charge transfers occur. Tribo.dsp series products detect the signal created by the changes in particulate concentration, as in the onset of a bag leak or an increase or decrease in flow. Unlike monitors that use only the DC or only the AC induction signals, thereby using only a portion of the complete electrostatic signal, TRIBO.dsp unified 3000 series combines the benefits of each method, providing the user with a superior reliable and repeatable signal, with electrical interference resistance - even in harsh industrial environments. They can activate operational functions such as alarms and relays or can generate continuous 4-20 mA or digital signals for trending and recording purposes.
