STAPS ISA100

Wireless Steam Trap Monitoring

STAPS ISA100
The STAPS ISA100 wireless steam trap monitoring device has been designed to efficiently monitor and evaluate steam trap operation.
It can diagnose both failed-open steam traps that leak live steam, and those that have failed-closed or are blocked, resulting in waterlogging, leading to plant damage, product spoilage and health and safety concerns.
Intrinsically safe, it is an ISA100 WCI approved device that is suitable for all trap types and is powered by a long-life battery.

  • Fully ISA100.11a compliant.
  • Continuous monitoring of all steam traps.
  • Reduces energy and emissions loss significantly.
  • Immediate identification of failure location for quick response/action.
  • Non-intrusive – no need to break into the steam line to install.
  • A range of clamps to suit pipework ranging up to 100 mm (4″).
  • No need for height access equipment to check trap operation.
  • Typically 3 years battery life.
  • Security assured wireless network certified to ISA100.11a.
  • Intrinsically safe for hazardous zones
