Data transmission modules in explosion-proof design

26 Ноября 2013 г.

For safe operation in premises with so-called explosive atmospheres, explosion-proof equipment must be used. Previously, Keller only produced primary instruments in explosion-proof designs. Today, we offer you a comprehensive autonomous solution that allows monitoring of level, pressure, and tempera...

Pumps for Pressure Generation

15 Октября 2013 г.

During operation, after some time, there arises a need to verify the accuracy of the displayed values within the declared permissible error or to adjust the measuring instrument, to correct the scale values – in other words, to perform calibration. For these purposes, LLC "Measurement and Control" o...

Differential Pressure Sensors
