Kuhnke Pneumatic Signal Indicators and Converters
Kuhnke pneumatic-electrically signal converters, also called pneumatic pressure switches or PE-converter, convert pneumatic pressure in electrical signals. They link between pneumatic actuators and the electronic control.
There are three different types of them.
The Kuhnke miniature PE-converter with fixed pressure range and M5 thread connection is meant for simple installation at confined spaces. Despite its small size the Kuhnke miniature PE-converter with silver contacts fulfills high-level functional safety. The adjustable and subplate mounted Kuhnke PE-converter is available in two different pressure and two electrical switching power ranges. This internal micro switch can be used as toggle switch and can be electrically connected with a plug-in socket for a higher humidity protection. The Kuhnke mechanical pressure wave switch was developed for very sensitive applications and reacts even on lowest pressure pulses from 3 mbar.
Kuhnke pneumatic indicators signalize if pressure is on. Due to direct installation into pressure pipe there is no need for an electrical status read out.
The color change of Kuhnke pneumatic indicators for switch panel mounting switches from black to green or black to red, depending on type. The indicator works by a colored pin that is driven out like the piston of a cylinder. By using a spring to fix the indicators body to the switch panel different panel thicknesses can be compensated. By an adapter washer the Kuhnke pneumatic indicators may be used for panel holes of 13 mm diameter or of 20 mm diameter.
The Kuhnke miniature pneumatic signal indicators do also have two colored pins, which drive out for some millimeters. The Kuhnke miniature pressure indicators are used for internal switch panel mounting as control or function display.
