Flame-retardant, chemical-resistant leakage sensors

Flame-retardant, chemical-resistant leakage sensors

Quick detection of even slight liquid leakage The liquid leakage sensor quickly detects and reports leaks from semiconductor factories, chemical storage facilities, chemical tanks, etc.
In recent years, digitization is rapidly progressing in hospital facilities, IoT devices, etc. and TATSUTA’s liquid leakage sensors are increasingly adopted in built-in water-cooling systems to dissipate heat from server equipment. In the meantime, several car manufacturers are also positively studying to incorporate the sensors into a water-cooled battery pack to dissipate heat from the batteries of EVs, of which use is expanding under growing concerns about the global environment.
We are adding flame-retardant, high-value-added products to our lineup to meet further customer needs.

Features

  • Addition of chemical-resistant leakage sensor, AD-FH-S The sensor uses chemical-resistant materials and can be used repeatedly. However, adhesion of corrosive chemicals may prohibit reuse.
  • Addition of flame-retardant leakage sensor, AD-BRS, AD-BFS, AD-BRL, and AD-BFL These sensors comply with flame-retardant standard NFPA262 (formerly UL910). NFPA: National Fire Protection Association
  • Monitoring a wide area with a single sensor (up to 100 meters) Unlike spot-type sensors, these sensors are connectable up to 100 meters, monitoring leakage from the piping of chemical solutions in the entire factory.
  • Quick detection of highly resistant liquids The sensor detects conductive liquid. The use of a highly sensitive detector reliably detects even high-resistance liquids. Depending on the conductivity, however, some liquids may not be detected.
