Low Pressure Monitor LDP ECHOLINE®

Corrosive Media Low Pressure Monitor ECHOLINE® Series

Incorporating stainless steel sensor technology into ECHOLINE®'s LDP Series product family results in a low pressure monitor capable of operating with corrosive media while monitoring low pressures. ECHOLINE®'s display, switching, analog output and "ECHO" functions are maintained with the added capability of operating with corrosive media. This improvement allows the unit to be used in applications that previously could not be monitored with the ECHOLINE® LDP series. The package is capable fitting two units in the same footprint of one old fashioned gage/switch.
