  • 604 Differential Pressure Switch
    Range: 20~1000Pa, Repeat Accuracy: ±2%FS

    Series 604 differential pressure switch has been designed for interlock purposes or no differential pressure detection. Where critical or high value property is to be maintained within specific environmental conditions, a single control should not be applied to function as both an operating and safety device. In such applications, a separate back-up control with alarm contacts should be wire...

  • A5 Differential Pressure Gauge
    Range: 0-0.5 in w.c. (min); 0-15 psi (max)? Accuracy: ±5%FS

    Clean design, small size and low cost with enough accuracy enable A5 for all but the most demanding applications. This gauge offers the latest design for a dial type differential pressure measurement. Similar to A2, it uses Magnet-helix mechanism, but it looks more compact while is easy to read and can safely operate at total pressures up to 30 psig. OEM applications include cabinet air-purg...
