LTF Flush Mount Transmitter



  • Best utilized in conjunction with viscous fluids or media which may clog a standard process connection, e.g. chemical & process engineering, food industry and pulp & paper


  • Unique flush stainless steel diaphragm eliminates any cavity that could form a build-up
  • 316-grade thick diaphragm provides higher overpressure and spike protection
  • Available ranges include vacuum up to 5,800 psi
  • Wide range of mechanical and electrical connections
  • Cooling tower option for increased temperature tolerance
  • Optional FDA-approved food-compatible oil
  • ±0.50% accuracy
  • NEMA 4X and NEMA 6P / IP65 and IP67
  • Customizable
  • RoHS compliant
  • 5 year warranty
