CYBK series pressure switch is a measurement and control component integrating pressure measurement and control. This series of products mainly use silicon piezoresistive pressure sensor as the pressure sensitive core, and can also be equipped with ceramic capacitor, sapphire, sputtered film and other pressure sensors. After programmable digital circuit correction and signal conditioning, the standard industrial application signal and switching value signal are output. According to different use modes, the product can output 1 to 4 groups of switching signals, which can realize the control of up to 4 pressure points. The customer can set the switching point freely according to the use needs.
According to its own characteristics, CYBK series products can be divided into external modulation type, explosion-proof type, digital display type and other models to meet different application needs of users.
CYBK series pressure switches faithfully serve various fluid measurement industries with their excellent performance. Especially in water treatment, power, medicine, and other industries, it has good adaptability and application advantages.
◆Internal continuous adjustment with control function
◆There is no dead zone in the adjustment, and the zero point to full scale can be adjusted arbitrarily
◆High stability and reliability

6.1 Explosion proof structure, which can be used together with explosion-proof safety barrier.
6.2 Applied to the fluid pressure measurement and control system, the external relay can complete a variety of control functions.
6.3 Filter and buffer measures shall be taken at the pressure interface end to prevent sensor damage caused by particles or impact.
6.4 The sensing diaphragm of the pure flat film sensor is exposed. It is strictly prohibited to touch it in any form, otherwise it may cause irreversible damage to the transmitter.
