Gas detector protective cover capable of preventing electromagnetic interference

Abstract

The invention discloses a gas detector protective cover capable of preventing electromagnetic interference. The detector comprises a transparent cover, a sensor adapter, a cable lead-in assembly, a sealing plug, a rear cover, a detector body, a hinge, a front cover, hasp locks, hasps, an insulating plate and a glass screen; the transparent cover is fixed on one side surface of the detector body; the two sides of the detector body are symmetrically and fixedly provided with the cable leading-in assembly and the sealing plug. The sensor adapter is fixed at the bottom of the detector body; the detector body is sleeved with the rear cover. One side of the rear cover is rotationally connected with the front cover through the hinge; the hasp locks are symmetrically fixed on one side, far away from the hinge, of the rear cover; and the hasps are symmetrically fixed at one side, far from the hinge, of the front cover. According to the device, a magnetic field can be effectively isolated, the detection interference of the magnetic field on the gas detector can be prevented, the gas detector can be well protected, the damage to the gas detector caused by outside collision can be reduced, andthe service life of the gas detector can be prolonged.

Description

technical field [0001] The invention relates to the technical field of gas detection equipment, in particular to a gas detector protective cover for preventing electromagnetic interference. Background technique [0002] A gas detector is an instrument that detects gas concentrations. The instrument is suitable for dangerous places with flammable or toxic gases, and can continuously detect the content of the gas in the air within the lower explosion limit for a long time. It can be widely used in gas, petrochemical, metallurgy, steel, coking, electric power and other industries with flammable or toxic gases. It is an ideal monitoring instrument for property and personal safety. [0003] According to the anti-magnetic cabinet provided by the existing patent CN201698755U, the device can effectively isolate the magnetic field, and the items in the protection cabinet will not be demagnetized, but it is not suitable for the anti-electromagnetic interference of the gas detector, a...
