A steam pressure switch is a switching device used to monitor and control steam pressure in a steam system.
feature
High-temperature and high-pressure adaptability: It can operate stably in high-temperature and high-pressure environments, withstand high-pressure shocks and temperature changes in steam systems, and can operate normally in high-temperature and high-pressure equipment such as boilers.
High sensitivity and precision: It can accurately monitor and control steam pressure, and adjust the trigger pressure range and accuracy to meet the needs of different application scenarios, such as playing an important role in some industrial production processes that require precise pressure control.
Fast response and high reliability: When the steam pressure reaches or exceeds the preset value, it can quickly trigger the corresponding operation to ensure the safe operation of the steam system and effectively prevent equipment damage or safety accidents caused by abnormal pressure.
classification
According to the working principle and structural characteristics:
Mechanical steam pressure switch: The mechanical connection device is used to sense and convert steam pressure, the structure is simple and reliable, but the sensitivity and precision are relatively low, and it is often used in occasions where the accuracy is not high and the working environment is relatively stable.
Electronic steam pressure switch: the use of electronic sensors to sense and convert steam pressure, with high precision and stability, can achieve precise control and monitoring, widely used in the field of high pressure control accuracy, such as medical apparatus, electronic equipment production.
According to the trigger method:
Differential steam pressure switch: By comparing two or more pressure signals to trigger the switch operation, when the steam pressure reaches the set value, the corresponding action is triggered.
Absolute steam pressure switch: trigger the switch operation according to the set pressure threshold, regardless of the difference between pressure signals, as long as the steam pressure reaches or exceeds the set value, it will be triggered.
Differential pressure steam pressure switch: compare the pressure difference between the two positions to trigger the switch operation. When the pressure difference reaches the set value, the switch action is initiated.
