Honeywell Kromschroder DG6U-3 Pressure Switch 

Kromschröder is a leading manufacturer of products and systems solutions for measurement and regulation of gases, for automation of industrial furnaces, for control of heat treatment processes and regulation of heating appliances.

This Kromschroder DG6U Pressure switch is for the monitoring of gas and air pressures (positive, negative and differential pressures). It features an internal lock and a manual reset.

The DG gas pressure switch monitors extremely low pressure changes and triggers a set function (swtich-on, switch-off, or switch-over) once a set switching point is reached. The switching point is adjustable using a hand wheel located on the front of the switch.
