OPTISWITCH 5000 C Series Vibration Level Switch

Brand: Krohne
OPTISWITCH 5000 C series is a level sensor that uses a vibrating fork for detecting level. It is designed for use in all liquids.

It is not affected by foam and external vibration. It is also unaffected by variations of product properties such as εr, viscosity etc.
Features
  • Output options: relay, transistor, NAMUR, contactless electronic switch and 2-wire 
  • 5000 series: plastic, Aluminum or stainless steel housings 
  • LED signal lamp for indicating the switching condition (with plastic housing only) 
  • 5000 series: large choice of materials for wetted parts. This includes 316L, Hastelloy® C4, enamel, ECTFE and PFA 
  • 5000 series: probe length: 53 to 6,000 mm / 2" to 236" 
  • Repeatability: ±2 mm 
  • Thread connections G/NPT 3/4"; flange sizes from DN25 PN40; triclamp 1" or 2" and other hygienic fittings
