Mining explosion-proof deviation switch GEJ40 Mining explosion-proof deviation switch GEJ40 Mining explosion-proof deviation switch GEJ40 Two pole deviation switch is made of high-precision aluminum alloy production die casting, with high strength, light weight and sturdy outer shell, and red paint on the outside, smooth and bright. Easy to discover. Used for emergency shutdown of belt conveyors due to belt deviation. Two pole deviation switch, also known as anti deviation switch. Used to detect the deviation phenomenon during the operation of belt conveyors, output alarms or shutdown signals based on the actual deviation amount of the belt, which can effectively prevent accidents caused by belt deviation. This series of deviation switches has a two-stage action function. The first level action is used for alarm, and the second level action is used for automatic shutdown. When the tape machine is running, when the tape deviates and comes into contact with the vertical roller of this switch, the vertical roller rotates. If the deviation continues to increase, the squeezing vertical roller will shift< Chemical explosion-proof thermal resistance WZPK-304S, WZPK-305S，WZPK-306S，WZPK2-305SA，.WZPK2306SA，WZPK-403S，WZPK-404S，WZPK-405S，WZPK-406S，WZPK2-405SA，WZPK2406SA，WZPK-503S，WZPK-504S，WZPK-505S，WZPK-506S，WZPK2-505SA，WZPK2506SA，WZPK-123S，WZPK-124S，WZPK-125S，WZPK-126S，WZPK2-125SA，WZPK2-126SA，WZPK-223S，WZPK-224S，WZPK-225S，WZPK-226S，WZPK2-225SA，WPK2-225SA，WZPK2-226SA，WZPK-323S，.WZPK-324S，WZPK-325S，WZPK-326S，WZPK2-325SA，WZPK2326SA，WZPK-423S，WZPK-424S，WZPK-425S，WZPK-426S，WZPK2-425SA，.WZPK2426SA，WZPK-523S， Explosion proof platinum resistor WZPK-524S, WZPK-525S，WZPK-526S，WZPK2-525SA，WZPK2526SA，WZPK-133S，WZPK-134S，WZPK-135S，WZPK-136S，WZPK2-135SA，WZPK2-136SA，WZPK-233S，WZPK-234S，WZPK-235S，WZPK-236S，WZPK2-235SA，WZPK2-236SA，WZPK-333S，WZPK-334S，WZPK-335S，WZPK-336S，WZPK2-335SA，WZPK2336SA，WZPK-433S，WZPK-434S，WZPK-435S，WZPK-436S，WZPK2-435SA，WZPK2436SA，WZPK-533S，WZPK-534S，WZPK-535S，WZPK-536S，WZPK2-535SA，WZPK2536SA，WZPK-163S，WZPK-164S，WZPK-165S，WZPK-166S， Platinum resistance element WZPK2-165SA, WZPK2-166SA，WZPK-263S，WZPK-264S，WZPK-265S，WZPK-266S，.WZPK2-265SA，WZPK2-266SA，WZPK-363S，WZPK-364S，WZPK-365S，WZPK-366S，WZPK2-365SA，WZPK2366SA，WZPK-463S，WZPK-464S，WZPK-465S，WZPK-466S，WZPK2-465SA，WZPK2466SA，WZPK-563S，WZPK-564S，WZPK-565S，WZPK-566S，WZPK2-565SA，WZPK2566SA，WZPK-173S，WZPK-174S，WZPK-175S，WZPK-176S，WZPK2-175SA，WZPK2-176SA，WZPK-273S，WZPK-274S，WZPK-275S，WZPK-276S，WZPK2-275SA，WZPK2-276SA，WZPK-373S，WZPK-374S，WZPK-375S，WZPK-376S，WZPK2-375SA，WZPK2376SA，WZPK-473S，WZPK-474S，WZPK-475S，WZPK-476S，WZPK2-475SA，WZPK2476SA，WZPK-573S，.WZPK-574S，WZPK-575S，WZPK-576S，WZPK2-575SA，WZPK2576SA，WZPM-101U，WZPM-201U，WZPM—002U，WZPM-102U， WZPM-202U，WZPM—001，WZPM-101S，WZPM-201S，WZPM-002，WZPM-102，WZPM-202，WZPM—301，WZP-011S，WZP-012S，WZP-013S，WZP-014S，WZP-015S，WZP-203S，WZP-205S，WZP-018，WZP-0110，WZP-2012， Refrigerator: LZT 20-100, LZT 20-200, LZT 20-300, LZT 20-400, LZT 30-100, LZT 30-200, LZT 30-300,LZT 40-100, LZT 40-200, LZT 40-300,BRC200,BRC400,BRC800,MRC200,MRC400,MRC800, Purification workbench: SW-CJ-1D, SW-CJ-1G, SW-CJ-2D,SW-CJ-2G, SW-CJ-1F,SW-CJ-1FD, SW-CJ-2F,SW-CJ-2FD, SW-CJ-1BU,SW-CJ-1CU, SW-CJ-1B,SW-CJ-1C, SW-CJ-1FB,SW-CJ-2FB,VS-840-1, VS-840-2,BXS-A2,BCS-A2,BJ-1CD,BJ-2CD, CJ-820, CCJ-1650, VS-1300, HS-1300, SHJ-875, SHJ-1450, VD-650, VD-850, HD-650, HD-850, SW-CJ-1D, SW-CJ-1G, SW-CJ-2D, SW-CJ-2G, SW-CJ-1F, SW-CJ-1FD, SW-CJ-2F, SW-CJ-2FD, SW-CJ-1BU, SW-CJ-1CU, SW-CJ-1B, SW-CJ-1C, SW-CJ-1FB, SW-CJ-2FB, HS-840U, HS-1300U, VS840U, VS-1300U, BCM-1000, BHC-1300IIA/B3, SW-CJ-DD, SW-CJ-2DD, SW-TFG-12, SW-TFG-15, SW-TFG-18, SW-CJ-90, FLB-1B, FLB-1A, FLB-1C, FLB-1200, FLB-2400, FLB-3600, AAS-700AS, AAS-700AR, PAU-1000, ZJ-600, ZJ-800, SW-CJ-1K, SW-CJ-2K, APB557, APB777, JC-900, JC-1200, SW-CJ-1E, SW-CJ-1ED, SW-CJ-2E, SW-CJ-2ED, SW-CJ-DA, SW-CJ-DB, far-infrared drying oven: 70-1766-3A, 766-2A, 766-1A, 766-0A, 766-3AS, 766-2AS, 766-0AS, 404-1, resistance furnace: SK2-2.5-13, SK2-2-13, SX2-2.5-10, SX2-4-10, SX2-5-10, SX2-8-10, SX2-12-10, SX2-2.5-12, SX2-5-12, SX2-10-12, SX2-4-13, SX2-6-13, SX2-8-13, SX2-10-13, SX2-8-16, SX2-12-16,XL-1,KSW-4D-11,KSW-4D-13,SXL-1002,SXL-1008, SXL-1016, SXL-1030, SXL-1208, SXL-1216, SXL-1304, SXL-1313, SX2-2.5-10N, SX2-4-10N, SX2-8-10N, SX2-12-10N, SX2-2.5-12N, SX2-5-12N, SX2-10-12N, SX2-4-13N, SX2-8-13N, SX2-8-16N, SX2-12-16N, SX2-2.5-10T, SX2-4-10T, SX2-8-10T, SX2-10-12T, Thermostatic oscillator: SHZ-A, SHZ-B,SHZ-C,THZ-92A,THZ-92B,THZ-92C,ZD-810,THZ-312,THZ-412,THZ-320,THZ-420,TQZ-312,LHZ-111,LQZ-211,ZDP-150,ZDP-250,HZP-150, HZP-250,DHZ-1102, DHZ-2102, DHZ-1112, DHZ-2112,WSZ-50A,WSZ-100A,WSZ-200A, SHY-2, SHY-3, SHY-2A, WHY-2, SHA-C, SHZ-82, THZ-82, THZ-82A, ZD-85, CHA-S, CHA-SA, ZD-2, ZD-3, ZD-4, HY-1, HY-2, HY-1A, HY-3, HY-4, HY-3A, HY-5, HY-5A, HY-6, HY-6A, HY-A, HY-B, MM-1, ZW-A, ZW-B, KS, SZ-1, TS-A, ZD-88, MM-1, MM-2, W2-100, W2-100S, W2-100SP, W2-180P, W2-180SP, W3-100SP, W5-100SP, W5-180SP, W10-100SP, W20-100SP, W50-100SP, F2HA, F5HA, F20H, F20H2A, F20H2B, F50H2A, F50H2B, F02J2B, F05J2B, F1J2B, F2J2B, F3J2B, F5J2B, F10J2B, F20J2A, F30J2A,FY20, FY50, VF20P, VF20S,
