Gladiator Admittance Level Switch

Gladiator Admittance Level Switch

The Gladiator Admittance Smart Switch is point level switch for liquids, solids and powders. The unit is suitable for a broad range of products and dielectric constants up to high temperature of 450°C (842°F).


  • Failsafe high-level / low-level alarm
  • High-level alarm
  • Low-level alarm
  • Blocked chute / Plugged chute
  • Interface detection
  • Pump control

Principle of Operation

The probe of the Admittance Level Switch forms one plate of a capacitance circuit, with the vessel wall making the second plate. The dielectric constant of the product between the probe and the vessel wall will cause a change of capacitance as the level approaches the probe. The change is detected, amplified and used to switch a relay for indication or control purposes. A special circuit is used to ignore product build-up between the sensing probe (active element) and guard, and also between the guard and vessel wall.
