Series DA-7035N Temperature Switches

Bulb and Capillary, Inert Gas Fill

The SERIES DA-7035N Temperature Switches include the same time-proven switching mechanism used in our Series DA pressure switches. Bourdon tube ensures high sensitivity and long life. Fully adjustable deadband makes units suitable for a wide range of control applications. Visible, calibrated dial and external adjustments make changing set points simple and fast.
