CROSWELL, MICHIGAN – Conveyor Components Company, a division of Material Control, has introduced a new generation of tilt level controls designed for dry bulk material level indication and control applications. These new UL listed control units are enclosed in a rugged cast aluminum housing with LED indicator lights to alert the operator of either the presence or absence of material. Equipped with a new surface mount PC board the unit now allows for a maximum of 1,525 metres 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 three different models for use in different environments. The model CT-105 control unit is NEMA type 4, 4X for use in general purpose outdoor applications and is dustproof and weather tight. The model CT-106 control unit is NEMA type 9 class II, groups E, F and G for use in hazardous locations. The model CT-107 control unit is NEMA type 7 class I, groups C and D explosion proof; NEMA type 9 class II, groups E, F and G dust ignition proof construction for use in hazardous locations.

When suspended from a fixed support, the probe indicates material is present when it is tilted a minimum of –9.5°C for the mercury version or –4.0°C 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 amp DP/DT output relay.

Two probe sizes are available. The CT-200G is a compact, 150-mm probe for use on small bins and hoppers where space is limited. The CT-201G is the standard 225-mm, heavy duty probe for applications where an abrasion resistant probe is necessary. The probes are intrinsically safe and UL listed only when used in conjunction our control units – the models CT-105, 106 and 107. 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 as a flow indicator on moving materials. Probes are airtight, dust tight, waterproof and come with a standard 7.5 metres of three-conductor 16-3 S0 cable. Additional cable lengths are available up to 1,525 metres.
