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

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.

-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

16.5bar SPDT Adjustable Pressure Switches -20~120℃

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

CE Approval Brass Connection Hvac Pressure Switch IP44 5-16bar

CE brass connection pressure switch Description What is a pressure switch sensor? A Pressure switch is a two-part device consisting of a sensing transducer and an electrical switch. The electrical switch opens and closes at a specific pressure often referred to as the Setpoint. Depending on the switch and the vendor, the switching pressure setpoint may be fixed or adjustable Q series single pressure controls can be not only used in fluorinated refrigerant, but also in the

RS485 DPT Differential Pressure Transmitter Greenhouse DPT Sensor

RS485 -1000~+1000Pa high quality plastic differential pressure transmitter for greenhouse Description KDP110 differential pressure transmitter detects differential pressure or gauge pressure and converts this pressure value into proportional electrical signal for inteligent building energy management system to measure the accurate pressure and flow required for building pressurization and air flow control. It is widely used in the monitoring of air or neutral gas,and a

-20~120℃ Brass Adjustable Pressure Switches

-20~120 brass adjustable pressure switches Description Q series pressure switch is a pressure switch used to detect flow failures in equipment. The medium can be liquid or gas, and the medium temperature can be as low as -20C to as high as 120C. The range is optional, and its connection to the medium is brass. material, can effectively prolong the service life. Pressure switches are widely used in high and low pressure protection control of household, commercial and
