Product Description

Product Description

UE's mechanical pressure switches are renowned for their simplicity and robustness. They operate on the principle of pure mechanical deformation leading to the actuation of a microswitch. When pressure is applied, different sensing pressure components such as diaphragms, bellows, or pistons deform. This deformation causes an upward movement, which, through mechanical linkages like lever springs, eventually activates the microswitch at the top, resulting in an electrical signal output.UE's vacuum switches are designed to operate in low - pressure environments. They work on the principle of mechanical deformation of sensing elements due to changes in pressure. When the pressure in the monitored area changes, the sensing components such as diaphragms, bellows, or pistons deform. This deformation is transferred through mechanical linkages to activate the microswitch, generating an electrical signal. The mechanical pressure switch setting in vacuum switches is typically of the continuous - displacement type, and they can be set to have one to three different setpoints. In vacuum - based manufacturing processes, such as in the semiconductor industry, these switches can be used to monitor and control the vacuum levels, ensuring that the manufacturing environment is maintained within the required specifications.

Technical Specifications
1.1 Pressure - Related Specifications
1.1.1 Pressure Ranges
UE pressure switches can cover a wide range of pressure values. For low - pressure applications, some models can detect pressures as low as 30 "Hg Vac ( - 1 bar in SI units). In high - pressure applications, certain switches can handle pressures up to 10,000 psi (689.5 bar). The ability to operate across such a broad pressure range makes UE pressure switches suitable for diverse applications, from monitoring the low - pressure gas flow in a laboratory to controlling the high - pressure fluid in an industrial hydraulic system.
1.1.2 Pressure Accuracy
The accuracy of UE pressure switches varies depending on the model and the application requirements. Some high - precision models can achieve an accuracy of ±0.5% of the full - scale range. This high level of accuracy is crucial in applications where precise pressure control is essential, such as in the pharmaceutical industry, where the pressure during chemical reactions needs to be tightly regulated to ensure product quality and safety.
1.2 Temperature - Related Specifications
1.2 Temperature Ranges
UE temperature switches can operate in a wide temperature range. The storage temperature range for many models is typically from - 54 °C to 71 °C. The operating temperature range can also be quite broad, with some models able to function in environments as cold as - 50 °C and as hot as 71 °C. In certain specialized models, the temperature range can be even more extreme, allowing them to be used in applications such as cryogenic storage or high - temperature industrial furnaces.

2.Temperature - Related Specifications
2.1 Temperature Ranges
UE temperature switches can operate in a wide temperature range. The storage temperature range for many models is typically from - 54 °C to 71 °C. The operating temperature range can also be quite broad, with some models able to function in environments as cold as - 50 °C and as hot as 71 °C. In certain specialized models, the temperature range can be even more extreme, allowing them to be used in applications such as cryogenic storage or high - temperature industrial furnaces.
2.2 Temperature Accuracy
The temperature accuracy of UE temperature switches can be as high as ±1% of the full - scale range in some models. This level of accuracy is important in applications such as temperature - controlled incubators in the medical field or in the precise temperature regulation of industrial processes, where even a small deviation in temperature can have a significant impact on the product quality or the efficiency of the process.
3. Electrical Specifications
3.1 Voltage and Current Ratings
UE switches are designed to operate at different voltage and current levels depending on the application. For example, some models are rated for 125/250/480VAC and can handle currents up to 15A. In applications where lower power consumption is required, there are models available with lower voltage and current ratings. The voltage and current ratings are carefully selected to ensure that the switch can safely and reliably control the electrical loads in the associated industrial processes.
3.2 Output Signals
The output signals of UE switches can be either analog or digital. As mentioned earlier, many electronic pressure and temperature switches offer a 4 - 20mA analog output, which is a standard in industrial automation for easy integration with other control devices. Some switches also provide digital outputs, such as solid - state relay outputs or digital communication interfaces like Modbus RTU or Profibus DP. These digital interfaces enable seamless communication with other devices in a network, allowing for remote monitoring and control of the switch.
