Steam Trap Monitor (STM) 2.0 Quick Installation Steps

Everactive launched a new steam trap monitoring solution in April 2021.  One benefit of this new solution is the ease of install for the customer. Below is a Quick Installation guide to walk you through the process of installation.




  • Remove any insulation and/or insulation jackets that are needed to expose the appropriate amount of surface on the trap assembly.  You'll need 1/2-inch of bare pipe on each side of the trap.
  • The Eversensor assembly and outlet probe should be seated on the pipe as close to the trap as possible.  Check for the presence of strainers, by-passes, or check valves, and avoid placement where the sensor measurements could be affected.
  • Install the STM 2.0 sensor on the trap.  
    • Loosen the nuts on the U-bolts- one side of the bracket is slotted so the U-bolt can pivot for quick installation.
      • Note: In most cases, the nuts can remain threaded on the U-bolt.  Keeping the nuts connected shortens installation time and reduces the risk of dropping them.

        Pivoting the U-bolt for install
    • Steady the assembly to ensure the Resistance Temperature Detector (RTD) is seated on the pipe.
    • Tighten the nuts on the U-bolt using an open ended wrench until the clamp supports the weight of the sensor assembly- typically 1/2 turn past finger-tight.
    • On the outlet side of the trap, use the U-bolt and nuts to secure the clamp to the pipe.  Tighten the nuts 1/2 turn past finger-tight.
    • Form the cable assembly for the remote probe- you can test fit the probe in the outlet side while estimating. 

      While forming the cable, do not bend the radius of the cable tighter than a 2" diameter circle.  As a reference point, use your wrist as a rough estimate.

      While test-fitting, do not insert the cable into the Eversensor without support, as this could break the fitting.

    • The outlet side probe uses a "bayonet" style connector- press inward against the spring pressure, and apply a quarter-turn to seat the probe.

    • After the cable has been formed to the appropriate distance, connect the cable assembly from the U-bolt to the sense node.  Press in until you hear or feel a "click", then turn the threads on the collar until finger tight.
  • If a spreadsheet is provided with trap tag and associated sensor MAC ID data, use the spreadsheet to determine which sensor is assigned to which trap tag.  Example: In the Boiler Room, trap tag ‘52A’ is pre-associated with MAC ID ‘0E:5B’. The same association data can be accessed directly from logging into this site and accessing the ‘summary trap pages’.
