RT-E Pressure Switch, Differential Pressure Switch & Thermostat
Brand: DanfossThe RT-E series consist of pressure and differential pressure switches as well as thermostats. The units are designed for industrial refrigeration and general industrial application in explosive zones According to 94/9/EC, Atex directive, explosive zone 1, for surface equipment, category 2.
It includes usage in refrigeration systems with ammonia, hydrocarbons and other applications where presence of flammable gases, vapours and mists are likely to occur.
RT-E pressure switches and thermostats for use in explosive zones incorporate SPDT changeover switch where contact position depends on pressure or temperature value of the system.
Features- Designed for use in explosive zone 1
- Versions with enclosure IP66
- Stainless steel frame
- Metallized front cover without window
