Cảm biến nhiệt 8500MC / MM, Đại lý chính hãng Kofloc Vietnam
The high-lift actuator allows this compact model to control a large fl ow rate.
・Equipped with a display and setting unit, this model can be op-erated by a 24 VDC power supply.
・The RS232C/RS485 communication function and integration function are provided as standard equipment.
・The 14-bit converter permits display and operation in 4-1/2 dig-its.
・Control of the fl ow rate of infl ammable gas is possible, because the heat generating part of the sensor is not exposed to gas.
・There are no limitations on the mounting position that may be employed.
・In addition to SV setting, fi ve other patterns can be set.
・Auto zero and auto close functions are also standard.
