Remote Sensor
(1) Remote Sensor for Macurco Ex Series

  Availability 2 Weeks  ]

The Macurco EX Series of Explosion Proof Gas Detectors are used for Class 1 Division 1 applications or harsh environments. A brilliant digital display indicates STEL, TWA and peak daily value concentrations as well as relay status. A three-color backlight will flash depending on the level of alarm for operator safety. Set-up and calibration is accomplished via non-intrusive magnetic interface that allows programming of all parameters. A remote sensor option is available for difficult or remote monitoring applications. Compatible sensor types include electrochemical and catalytic bead options to provide monitoring solutions for a wide variety of toxic and combustible gas applications. Standard outputs include Modbus RS-485, 4-20 mA and three user programmable relay contacts.
