electric float switch-switch DPE - 3
DPE - 3 float electric level switches are designed to control the liquid level in various process tanks, including the level sensors. Level sensors are not intended for liquids that precipitate, crystallize, containing suspended ferromagnetic particles, as well as causing destruction of 08KP steel and aluminum alloy AL-2. Level sensors are manufactured in accordance with climatic design U and location category 2 GOST 15150-69. In terms of resistance to vibration, level sensors must comply with version 1 in accordance with GOST 17167-71. DPE-3A level sensors are operational after seismic impacts equivalent to vibration loads in the frequency range from 1 to 50 Hz with an acceleration of 3.2 to 15 m / s2. The level sensors are not intended for use in hazardous areas.
