Kofloc Mass Flow Controllers Model PSK-83CE/PSK-85CE/PSK-38DSⅡ

Description

To achieve the high-speed response and $\pm 1.0\%$ accuracy specified by Kofloc mass flow instruments, a stable power source is mandatory. The PSK Series is designed to address the unique electrical demands of flow control technology. Standard industrial power supplies often produce electrical “noise” that can interfere with the minute millivolt signals generated by thermal flow sensors. The PSK-83CE and PSK-85CE are high-performance modules typically used to drive analog controllers (like the 3100 or 3660 series), providing the dual-polarity $\pm 15$ VDC required for bridge-circuit sensors.

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.
