Дифференциальный переключатель давления QYD
Adjustable Pressure Switch, Differential Pressure Controller for Water Description QYD differential pressure control is normally used in gas or liquid system to control the pressure difference between the gas/liquid pipeline and the circuit. A typical application is to install the controller in the bypass pipeline near the system pump. When the system pressure difference increases and exceeds pre-set pressure, the control valve will open and more liquid/gas goes through the

Adjustable pressure switch for water pump Description How do pressure switches work? An electro-mechanical pressure switch works by applying pressure to either a diaphragm, bellow or a piston to exert motion. The motion can create electrical contact in a microswitch launching an alarm or creating an action, for example switching off a compressor. An electronic pressure switch generally uses a piezo-electric crystal; when deformed a piezo crystal emits an electric current.
Восстановленный CE переключателя воздушного давления SPDT регулируемый аттестовал
Adjustable air pressure switch Description The pressure switch adopts the pressure sensor and transmission circuit with high precision and high stability, and then uses the special CPU modular signal processing technology to realize the detection, display, alarm and control signal output of the medium pressure signal. Pressure switch can be widely used in the fields of petroleum, chemical, metallurgy, electric power, water supply and other fields to measure and control the
16.5bar SPDT регулируемые переключатели давления -20 ~ 120°C
16.5bar -20~120℃ SPDT adjustable pressure switches Description Q series pressure switches are very popular and important in plant control and instrumentation,they are used for regulating, monitoring and alarm systems in industrial applications. With built-in SPDT micro switch, they are mainly used in control circuits and power circuits, so also called pressure control switch, pressure controls or pressure relay. Q series pressure switches will make a changeover when
