The important element of pressure switch
1. The bellows, bourdon tube: elastic element of pressure switch mainly are made of the stainless steel material, elastic performance are better, the difference is small bellows measurable pressure range, and bourdon tube pressure range can be obtained.
2. The diaphragm: mainly made of fluorine rubber material is commonly used in pressure switch elastic sensitive element.
3. Precision: pressure switch the accuracy of the final measurement results and the actual value, the higher accuracy, the higher the reliability of the pressure switch.
4. Double pole double throw: pressure switch of double pole double throw a symmetrical around the public side, including two groups often opened normally closed contacts.
5. Single pole double throw: single-pole double throw with double pole double throw on the contrary, it is composed of a common end and closed contact.
6. The maximum pressure value: pressure switch can withstand the range of maximum pressure.
7. Pressure: the pressure switch are able to keep the most basic performance can withstand maximum pressure, is in the normal working state can bear the biggest pressure.
8. Upper and lower limits: pressure rises to the set value, the contact point movement, the circuit conduction, system equipment to return to work.
