Low Pressure Monitor LDP ECHOLINE®

Low Pressure Monitor LDP ECHOLINE® Series

LDP ECHOLINE® was designed in cooperation with a leading semiconductor manufacturer to provide state-of-the-art low pressure monitoring of gas cabinet exhaust systems. "ECHO" (Electronic Circuit Health Output) diagnostics alert the user to loss of external power or internal electronics failure. LDP ECHOLINE’s® unique Maintenance Mode feature prevents false trips during ventilation system balancing. Four LDP ECHOLINE® units fit into the space of one old- fashioned gauge/switch thereby reducing overall panel costs.
