THE INSTRUMENT

These Single Point Wall Mounted Instruments work on 18-24VDC and has a weather proof sensor housing fitted on a Junction box. They use an IP 55 enclosure for the electronics as standard. They are provided with two alarms both audible and visual along with relays and output of 4-20 mA. They are meant for continuous operation of area monitoring with continuous read out, plus vital status indicators

FEATURES

Type of sensors that can be connected are Electrochemical, NDIR, Pallister, and Thermal conductivity  depending on gas and application.

      Three  Wand operated  keys .

      Two Alarms audible and Visual along with acknowledge and reset buttons, both set points viewable from front face using a wand.

      One Fault alarm

      One NO,C,NC potential free relay contact per alarm

      4-20 mA Output for PLC, DCS etc.

APPLICATIONS

Used in slightly unprotected atmospheres in plant for instrumentation, for detection of toxic gases in work places or enclosed spaces for safety of personal
