High Temperature Explosion-Proof Flow Switch

Product Name: High Temperature Explosion-Proof Flow Switch Model NO.: FR12B Media Type: Liquid Type: Thermal Type Certification: Pcec IP Rating: IP65 Trademark: NOIKE Transport Package: Transport Package Specification: IP65 Origin: Shanghai HS Code: 9026 Product Description Product Overview:The explosion-proof mark is ExdIICT6 GB, which meets the requirements of GB3836.1 and GB3836.2 related standards. It is suitable for the explosive mixture of zone 1and zone 2of explosive dangerous environment, class yi 1A, 2B, 3C, ignition temperature group is T1~T6 group of flammable gas or explosive mixture of vapor and air. It can be widely used in the flow detection of inflammable and explosive places such as petroleum, chemical industry, electric power, metallurgy, etc.This product is designed based on the L. V. King heat exchange principle. The front end is equipped with aflow sensor in aclosed probe, which contains two resistors, one of which is heated as adetection resistor, and the other is not heated as areference resistor. When there is no medium flowing, the temperature difference between the two resistors is the largest. When there is medium flowing, the temperature difference between the two resistors becomes smaller. The size of the temperature difference is only related to the flow rate of the medium. The larger the flow rate, the smaller the temperature difference, and the smaller the flow rate, the greater the temperature difference. At the same time, it is related to the thermal conductivity of the medium itself. When the flow rate is lower than or higher than acertain set value, the relay is turned on or off, and aswitch signal is output.This content is for reference only.
