Dwyer differential pressure switch 1620
Micro differential pressure switch
High repeatability, with a repeatability accuracy of ± 1%
The 1620 series micro differential pressure switch is reliable, durable, and easy to install. It is the highest precision diaphragm sealed micro differential pressure switch. 1626 and 1627 have the same design and structure, except that 1626 is a single switch and 1627 is a dual switch. The dual switches of 1627 are independent and can preset set point values. The diaphragms of both models of switches are strictly sealed to ensure no leakage.
Note: Can only be used for air or other compatible gases.
