Each instrument in the series can be driven by a +24 VDC power supply. In addition, the “I” family in the 400 Series features an IP-65 enclosure which will allow the use of the instrument in a wide variety of environments. The electrical connection can be made via either a terminal strip located inside the enclosure or through an IP-65 compatible electrical connector, which can be quickly connected. All of the instruments include both analog and digital I/O. This signal is linear to the full scale flow rate of the measured gas. Intensive research has resulted in a vastly improved linearity. This becomes more apparent when different gases are measured. The 400-I series minimizes the large changes in linearity that typically occur when the flowing medium changes.
