DESCRIBE

In any case, if you want to display the process pressure and switch off the circuit locally, the electrical contact pressure gauge will be ideal, and the switch electrical contact (electronic electrical contact for alarm) can be turned on and turned off the electrical control circuit according to the pointer position of the instrument. The switch electrical contact can be adjustable within the overall range. Usually, the elevator points are installed under the dial, and only a few are installed on the dial. The instrument pointer (actual value pointer) can rotate freely in the whole range, regardless of the setting. The setting pointer can be adjusted by the removable adjustment key in the window. The switch electrical contact not only contains multiple electrical contacts, but also can set a single set value. When the actual value pointer exceeds or below the set value, the electrical contact is switched. This pressure gauge is manufactured according to DIN 16085 standard and meets the safety requirements of all relevant standards (e. g. EN 837-1) and specifications and can be used for working pressure of high pressure vessels. Switch electrical contact includes magnetic auxiliary electrical contact, dry spring electrical contact, induction type electrical contact and electronic electrical contact. Induction electrical contact may be used in hazardous areas. As for connecting PLC, the electronic electrical exchange point and dry spring electrical contact can be used.
