MODEL JS-10 / JS-30
Magnetic Point Level Switch

The JS-10 (1 amp) and JS-30 (3 amp) switches are magnetically actuated point level switches for use with magnetic liquid level indicators. Magnetic coupling through the chamber wall keeps these switches isolated from process fluid and pressure, allowing setpoints to be adjusted on the fly.

  • No process piping or valves required
  • Retrofit onto existing MLG installations
  • Internal bias magnet maintains state in high-vibration environments
  • Available in SPDT (one internal switch) or DPDT (two internal switches)
  • Available with flying leads (no enclosure), Epoxy-coated Aluminum enclosure, or 316 Stainless Steel Enclosure
  • Class I, Division 1, Groups B, C, D
  • Class I, Division 2, Groups ABCD
  • Class II and Class III, Groups EFG
  • ATEX and IEC ratings (pending)
  • Maintenance-free

MODEL JP-450
Pneumatic Level Switch

The JP-450 is a magnetically actuated “no bleed” pneumatic point level switch for use with magnetic liquid level indicators. Magnetic coupling through the chamber wall keeps the switch isolated from process fluid and pressure, allowing setpoints to be adjusted on the fly. Two JP-450’s can be coupled with a JPLR latching relay to give plug-and-play dump/fill valve control (see JP-450 data sheet).

  • No process piping or valves required (except customer pneumatic lines)
  • Retrofit onto existing MLG installations
  • “Snap-action” design maintains state in high-vibration environments
  • Accepts filtered air or gas supply
  • Field configurable (High/Low level)
  • 316 Stainless Steel enclosure
