Earth/Ground Resistance Online Detector/Tester China Factory(Non-Explosion proof, Wired)
https://www.sltup.com/Earth-Resistance-Online-Detector-Factory-Price-China-Supplier-Non-Explosion.html
Sunlight grounding resistance online monitoring system passes various tests, such as The highest harsh level requirements stipulated by surge, static electricity, pulse group, radiation immunity, power frequency magnetic field immunity, voltage short drop, radio frequency magnetic field conduction harassment, That is to say, Sunlight Earth/Ground Resistance Online Detector/tester (Explosion proof) can work in a stable strong interference environment.
Wired network system: data transmission through RS485 communication protocol, composed of main communicator (concentrator), monitoring software, power adapter, computer, etc., suitable for close distance, convenient construction wiring.
also, the product passes the 100 KA lightning surge test. That is to say, during the actual operation of the product, when 100 KA lightning current pass through, Sunlight Earth/Ground Resistance Online Detector/tester detector works normally.
Class of protection: IP65 and WF2, can be used outdoors
Power supply: 85~265VAC/DC
Range of resistance: 0.01Ω~200Ω
Resolution ratio: 0.001Ω
Precision: ≤1Ω(Error ≤10mΩ, 20℃±5℃, 70%RH below); ≤100Ω(Error≤±1%)
Working Environment: -40℃~85℃,Humidity ≤95%RH (no condensation)
Overflow indication: If the value is larger than 100Ω, the" -- ”symbol is displayed
Alarm output: Panel alarm and indicator light triggered simultaneously; Dry contact (with 5A / 220VAC)
Communication interface: RS485 (ModBUS RTU protocol), photoelectric isolation, 1200 m /9600bps
Size of product: 200mm×280mm×112mm
Ground wire perforation dimensions: 54mm×21mm, Closed mouth type (can pass through 54mmX10mm flat steel or Ф20mm cable)
Installation: The ground wire passes through the central hole of the detector and fixed on the ground flat steel
