Specification

MJ - Ⅱ pointer type SF6 density relay is widely used in high pressure switch electrical appliances industry. Draw in the same industry at home and abroad advanced technology, the product has a unique advanced temperature compensation function. The product is of high pressure switch, electrical equipment within the SF6 gas density test and control, to ensure normal operation of equipment, prevent damage of SF6 gas leak equipment, thus to protect equipment.

The working principle of MJ -Ⅱ pointer type SF6 density relay was SF6 gas pressure after temperature compensation to display the SF6 gas density, the product is in use within the temperature range of any temperature indicating pressure value is room temperature 20 °C (density) of pressure values
