Introduction 

The  RMU1  Remote  Monitoring  Unit  is  part  of  the  Mobiltex  Data  Ltd.  corTalk

  family  of  cathodic  monitoring  and 

control  products.  Mobiltex  Data  Ltd.  was  formed  in  1985  and  specializes  in  the  design  and  manufacture  of  high 
reliability, industrial mobile data systems for the communications, transportation and utility markets. Mobiltex has been 
providing solutions for the cathodic monitoring industry since 1991. 

The RMU1 is a low cost, high reliability device intended to monitor coupons and bonds. The device is available in two 
satellite  (RMU1-S  and  RMU1-I)  and  one  cellular  (RMU1-G)  communication  configurations.  The  field  hardware 
consists of a single component that is usually mounted inside a plastic test station. The device operates for 10+ years 
from internal, low cost, field replaceable batteries. This self-powered solution can be used to monitor coupons and bonds 
without the requirement for nearby line or solar power sources.  The RMU1 has integral high-energy surge suppression 
and provides unprecedented lightning immunity because there are no connections to electrical ground. 

The RMU1 monitors and transmits eight channels of information.  An integral IR proximity sensor can be used as a cap 
open sensor or tamper detection alarm. The RMU1 measures temperature and internal battery voltage. A user accessible 
magnetic switch allows the transmission of uniquely identified messages that can be used to record site visit information.  

Measurement  data  is  wirelessly  transmitted  to  the  Mobiltex  corView  servers.  CorView  manages  all  field  data 
communications, maintains three years of measurement data, sends alarm exception and system performance emails, 
and provides password protected remote customer access. With the proper credentials, corView can be accessed using 
an Internet Explorer web browser. The measurement data is presented in an intuitive tabular format or graphical mapping 
display  that  color-codes  abnormal  measurement  or  site  conditions  for  quick  user  interpretation.  CorView  can  also 
provide near real-time email notification of abnormal measurement and alarm conditions.
