How to Program a Switch for Manual Reset

Compact Low Differential Pressure Switch with Manual Reset, Series 1900MR

Several applications require manual reset switches, which are switches that need to be physically reset by an individual for a process to continue or restart. A manual reset is often needed when an area has to be inspected prior to equipment restart. This can help to ensure the safety/inspection of both equipment and other individuals in the area.

Some switches have a mechanical manual reset (such as the Dwyer Series 1900, 1831, and 1800).

Dwyer vs COVID-19 | Monitoring Air Flow & Pressure in Hospitals

Dwyer is committed to aiding in the fight against COVID-19. We have several products that are used in hospitals and the production of ventilators. Ventilators are used to aid COVID-19 patients who have low oxygen levels, support their breathing, and bring oxygen levels to a safe range.

Isolation Room Application

In addition, isolation rooms need to remain at specific pressures and air cycles, so as to not risk exposure of airborne contagions to other patients or healthcare professionals during treatment. Today we’ll be discussing some of the products that Dwyer manufactures that are used in these applications. Continue reading “Dwyer vs COVID-19 | Monitoring Air Flow & Pressure in Hospitals”
