Q830 Series Dual Pressure Switch
IP44 Adjustable Pressure Switches Protecting Pump Compressor CE Approval Description KPS series dual pressure controls can be not only used in fluorinated refrigerant, but also in the air and liquid (allowed liquid temp. -20 to 120C) Adjustable range and differential settings. Renovated SPDT micro-switch ensures the reliable switch function. Flexible mounting bracket suits various kids of application. Upper lid is optional (IP44) Various connections are available on request.
-0.5~3bar Adjustable Pressure Switches For Pumps
-0.5~3bar adjustable pressure switches for pumps Description In the mechanical system, the air bag interface of the controller is connected to the pressure port. When the pressure in the mechanical system exceeds the pressure set point of the controller, the contacts of the microswitch of the controller are opened, and the circuit is cut off or connected, and the machine stops or starts the operation. When the pressure in the mechanical system drops to the set value of the
Q830 Dual Pressure Switch
Dual pressure switch for havc Description A dual pressure control from Grainger helps to protect commercial refrigeration and air conditioning systems. Dual pressure controls combine high-pressure compressor protection with low-pressure cycling or safety functions. Some models offer a visible pressure scale and can be adjusted through the range without removing the cover. Manual reset models are trip-free. Q830 series dual pressure controls can be not only used in fluorinated
Stainless Steel Adjustable Pressure Switch Dual IP54
Pressure Switch Dual Description Q830 Dual Pressure Controls are designed for use on high and low pressure applications in refrigeration, air conditioning, and heat pump systems. This control react to changes in either low or high side pressures, providing single-device control of the compressor or other electrical device. Q830 series dual pressure controls can be not only used in fluorinated refrigerant, but also in the air and liquid (allowed liquid temp. -20 to 120C)
Renovated SPDT Adjustable Air Pressure Switch CE Certificated
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
Stainless steel Dual Adjustable Pressure Switches For Water Pump
Dual adjustable pressure switches pressure switch water pump Description The working principle of the pressure switch: when the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor will move instantaneously, and the switch connector will be connected or disconnected by connecting the guide rod. When the pressure drops to or rises to the rated recovery value, the disc will reset instantaneously, and the switch will reset automaticall
-0.5~3bar SPDT Brass Adjustable Pressure Switches
-0.5~3bar SPDT brass adjustable pressure switches Description The pressure switch is a device combined with an electrical switch. When the preset fluid pressure is reached, the switch contact will act. It is mainly used in power plants, petrochemicals, metallurgical industries and other industrial equipment to output alarm or control signals. The Q series pressure switch can monitor the pressure of liquid or gas at a temperature of -20~120C, and respond to the change of
Dual Pressure Switch for HVAC/R Compressor , Low Pressure Auto Adjust
Dual Pressure Switch for HVAC/R Compressor, Low Pressure Auto Adjust Description Where should a pressure switch be installed? Except for special installations such as constant pressure water pump systems in-well systems that do not use a conventional water pressure tank or water storage tank, the pressure control switch should be located as close to the pressure tank as possible. Q830 series dual pressure controls can be not only used in fluorinated refrigerant, but also in
Q Series Single Pressure Switch
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.
