648B-17

648B-17 is a series 648B differential pressure transmitter which is designed to be used with clean, dry air and other non-corrosive gases. Each unit features a push activated zero function and an associated LED light indicator. With the convenient push button, zero calibration can be performed without any additional equipment, which significantly reduces time and cost for users. The dual colour LED indicates if the transmitter is at normal operation, overpressure, or in the process of zero calibration. The enclosure consists of a flame retardant plastic top cover and a stainless steel bottom plate for ruggedness.
