I. Brief Introduction
Non-Contact Grounding Resistance Online Detector
is our company devotes ourselves to Grounding
resistance test technical research
’
s another new high-tech product for more than ten years, built for online
monitoring grounding down lead connection status, return circuit grounding resistance and metal return circuit
connection resistance well-designed manufactured. on-line testing, non-contact measurement
,
grounding wire
pass through the hole, definitely not influence grounding for lightening effect and facilities
’
normal operation, real
time on-line testing. Detector provides power supply and
RS485
signal interface, provides standard
MODBUS-RTU
communication protocol, which is convenient for doing second development. Detector can
install and use singly, and also set up a network, realize long-distance on-line monitoring. Detector internally
installs sensor and circuit board, completely seals, possesses features of protection against rain, dust prevention,
resistance to high low temperature, corrosion prevention, inflaming retarding etc., ensure high-accuracy, high
stability and high reliability of long time on-line monitoring outdoors, underground mine and indoors.
Non-Contact Grounding Resistance Online Detector
applies to electric transmission line pole ground
connection, underground mine device ground connection, Meteorological lightning protection ground connection,
petrochemical engineering ground connection, communication ground connection, rail facility ground connection,
building the warehouse ground connection, electrical equipment ground connection etc..
II. Model Difference
Model
Difference Explanation
ETCR2800B
Detector without display, user needs to do secondary development according to offered
RS485 communication protocol, to monitor the detection data.
ETCR2800C
Detector owns LCD display, Alarm setting, audible and visual alarm instructions and
can be independent installation and use, and also does secondary development
according to offered
RS485
communication protocol and organizes a network.
