Application:
1.Can be used in zone 1and zone 2 hazardous gas lpaces.
2.Can be used in explosive gas or steam atmosphere: calss llA,llB; it's temperature grade:casss T1-T4.
Features:
1.The prouducts are made of float ball and isolating explosion bodycase that build-in contact ,the float will alarm and control with the magnetic force axis swaying while the liquid level controller.
2.The isolating explosion case is made of casting aluminium alloy and the surrface is spayed with plastic .The float ball is made of stainless steel Gr18Ni9.
3.The moveable parts float ball separate with the contactor will avoid the leakaging of liquid level controller.
4.Suitable for GB3836-2000.IEC60079 standard request.
