UE压力开关H100-514（US UE pressure switch H100-514 ）

US UE pressure switch H100-514 Summary   100 series pressure and temperature switches are a series of switches with very good performance and price ratio. They are widely used in industrial processes and OEM users. The integrated design and the shape and structure of the shell make them stronger and more convenient for wiring. All-weather series switches have a variety of micro switches and a variety of process interface options to meet various needs. With its own characteristics, the 100 series is widely used in heat tracing, antifreeze protection, process equipment (pumps, compressors), alarm panel input and flame arresting system.  Advantages of UE products:   ◆ Complete range 1/ Pressure switch adjustable range from -0.1 to 62MPA  2/ Temperature switch from -50 to 538 degrees Celsius 3/ Differential pressure switch adjustable range from -0.1 to 3.45MPA  3/ Sensing There are three types of components: diaphragm, bellows, and piston 4/ There are switches for special occasions, and there are also small and low-cost switches specially designed for OEM users 5/ Both fixed dead zone and adjustable dead zone pressure switch 6/ Some mechanical Differential pressure and temperature switches can be equipped with on-site indication 7/ There are 2-inch pressure port anti-blocking switches and sanitary flat diaphragm switches product is compact in structure, durable in use, beautiful in appearance and fine in processing Many models of welded stainless steel design structureThe pressure switch adopts a welded stainless steel diaphragm or a welded stainless steel bellows structure, omitting the "O" ring, this non-leakage design improves the fire performance in hazardous explosion-proof areas, and at the same time increases the pressure resistance. Features   ● Meet UL list and cUL certification and CE standards ● Single point output (SPDT or DPDT)  ● Welded stainless steel diaphragm  ● Water column level low pressure and differential pressure switch  ● A variety of optional sensing materials can meet various  corrosivenessMedium requirements  ● Clean stainless steel sanitary interface  ● Very wide adjustable dead zone to meet the needs of pumps  related terms Accuracy: A value indicating the degree of precision of the device, including linearity, tolerance, hysteresis, repeatability, etc. At present, the highest precision of Nagano's pressure switch can reach ±0.5%FS, and the model is CB33. Maximum pressure (Max.P): the maximum value of the pressure range. Full Scale (FS): The difference between the maximum and minimum values ​​of the pressure range. Connection difference (dead zone): It refers to the difference between the switch setting action value and the reset value. For example, when the set value is 1MPa and the actual reset value is 0.9MPa, the connection difference is 0.1MPa. Working temperature: refers to the temperature range in which the internal mechanism and sensitive components of the instrument will not undergo continuous deformation during operation. Generally, the recommended operating temperature range of the pressure switch is -5~400C. If the temperature of the medium is too high, it can be considered to add an accessory siphon (filling shape) to achieve the purpose of cooling. SPDT (Single Pole Double Throw): Consists of a normally open, a normally closed contact and a common terminal. DPDT (Double Pole Double Throw): It consists of a symmetrical left and right common terminal, and two sets of normally open and normally closed terminals. Upper limit one contact (normally open): When the pressure rises to the set value, the contact will act and the circuit will be turned on. Lower limit one contact (normally closed): When the pressure drops to the set value, the contact will act and the circuit will be turned on.
