a different VG7000 series model should be selected to ensure proper flow dynamics

excess capillary can be carefully coiled

the "New Style" does not require an atmospheric vent connection

provided the switch is mounted according to the manufacturer's original orientation to prevent moisture accumulation in the diaphragm

The single-fabric wrap design increases flexibility and makes it significantly more tolerant to pulley misalignment and slippage compared to raw-edge alternatives

Dwyer Instruments 1638-1 Pressure Switch 321142-301 a different VG7000 series modelThe Dwyer Instruments 1638 1 Pressure Switch is a high precision, large diaphragm pressure switch designed specifically for industrial service and HVAC applications like duct air control, damper positioning, and air conditioning system monitoring. This 1630 series model operates within a precise range of 0. 20" w. c. to 1. 0" w. c. with a tight approximate deadband of 0. 04" to 0. 06" w. c., ensuring reliable differential pressure sensing for air and
