Tilt Level Controls Model CT

Aug. 14, 2013
Conveyor Components' tilt level controls are designed to alert the operator to the level presence of bulk materials.

Tilt Level Controls are designed for dry bulk material level indication and control applications. These UL Listed Control Units are enclosed in an aluminum housing with LED Indicator lights to alert the operator of either the presence or absence of material. Equipped with a surface mount PCB, the unit allows a maximum of 5,000 ft of cable between the control unit and probe, permitting placement of the control unit in an easily accessible area. The control units are available in 3 different models for different environments.

  • Model CT-105 Control Unit is NEMA Type 4, 4X for use in general-purpose outdoor applications and is dust-proof and weather tight.
  • Model CT-106 Control Unit is NEMA Type 9 dust ignition proof construction for use in hazardous locations.
  • Model CT-107 Control Unit is NEMA Type 7 explosion-proof and NEMA Type 9 dust ignition-proof construction for use in hazardous locations.

When suspended from fixed support, the probe indicates material is present when it's tilted a minimum of 15-deg. for the mercury version or 25-deg. for the non-mercury version. The surface mount PC board is resistant to shock and vibration and has a logic selector switch and adjustable time delay to prevent false signals.


The Control Unit has a 5 A DP/DT output relay. Two probe sizes are available:

  • CT-200G is a compact, 6-in. probe for use on small bins and hoppers where space is limited.
  • CT-201G is a standard 9-in., heavy-duty probe for applications where an abrasion-resistant probe is necessary.

Both Probes are available in stainless steel for corrosive environments and optional fittings are available to permit easy suspension from fixed supports. Paddle options are available for use on moving materials as a flow indicator. Probes are airtight, dust-tight, waterproof, and come with a standard 25 ft of 3 conductors 16-3 S0 cable. Additional cable lengths are available up to 5,000 ft.
