DWYER Series 648B & 648C Differential Pressure Transmitter
RM 0.00
Description
Series 648B & 648C Differential Pressure Transmitter
Unidirectional and Bidirectional Ranges, Removable Terminal Block
The DWYER Series 648B & 648C Differential Pressure Transmitter are 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. DWYER Series 648B & 648C Differential Pressure Transmitter convenient push-button, zero calibration can be performed without any additional equipment, which significantly reduces time and cost for users. The dual color LED indicates if the transmitter is at normal operation, overpressure, or in the process of zero calibration.
