Steam Systems Inspection


Keep Your Steam Clean, Safe And Energy-Efficient

Your steam traps contribute to product quality, energy conservation, component longevity and employee safety. Yet it is not uncommon to have as much as 50% of steam traps in a failed state.

SDT 16dec19 2As hot steam travels from your boiler to the point of use, some cooling is inevitable. The result is condensate and gases. The job of the steam trap is to isolate and remove these impurities from the live steam. Steam traps that function properly help maintain purity and efficiency throughout the system.

The best way to test steam trap function is to listen to them with an ultrasound solution. With ultrasonic detection you’re able to hear:

  • The opening and closing of your steam trap
  • Silence if the steam trap is stuck in the closed position
  • Turbulent flow if the steam trap is stuck in the open position
  • Mechanical clattering if the steam trap’s valve is fluttering open and shut

Manage The Condition Of Your Steam Traps

Working steam traps preserve pure, safe and energy-efficient steam. Rely upon the SDT270 and SDT200 ultrasound solutions to monitor the condition of steam traps and determine which ones need to be replaced.

Both the SDT270 and the SDT200 offer optional, onboard temperature measurement. Test temperature differential upstream and downstream of the trap, in conjunction with your ultrasound data, for a more thorough assessment of trap condition.

Sensors For Steam Trap Testing

By monitoring these four numbers on your ultrasound solution, you’re able to keep a pulse on the health of your facility and move from a reactive maintenance program to a condition-based approach.

Internal Non-Contact Temperature Sensor

The internal non-contact temperature sensor measures temperature in °C, °K, °F and °R, from -70°C to +380°C and stores the result in the SDT detector's memory.
