Blocked Chute Switches - AMETEK DrexelbrookBlocked chute, chute

AMETEK Drexelbrook is the industry leader in RF Admittance and they extend that experience to a unique range of blocked chute switches (plugged chute). The RF admittance technology enables a reliable measurement in the presence of build up and direct impact from heavy materials. Heavy duty, flush mounted blocked chute sensors ensure the highest resistance to abrasion and damage. Being flush mounted they won't be the cause of a blockage.

The Drexelbrook blocked chute range is available in a various configurations to custom match your application requirements and can be easily adapted for changing conditions.

Drexelbrook's Blocked chute switch is the ideal choice for hard wearing product or where users want a no fuss, long lasting instrument for the reliable detection of blocked chutes or point level in chutes and hoppers without the disruption of coatings. Blocked chute sensors are also available in curved shapes to perfectly fit round chutes.

Why is RF Admittance the best choice for your Blocked Chute Applications??

Unlike other conventional technologies that need either a break in the line of site or a sufficient force for a mechanical alarm. RF Admittance is looking for a the continuous link to ground only created by a blockage of material. This means you can freely flow product over the face of Drexelbrook's blocked chute sensors without alarm. Couple this with the superior coating rejection provided by Drexelbrook's Patent "Cote-Shield" technology, and you have a uniquely capable Blocked Chute Switch ready for the harshest of conditions.

Blocked Chute Switch - Dry Product and Coatings
RF Admittance switch for detecting blocked chutes

The general purpose blocked chute switch from Drexelbrook will take case or most of your blocked chute applications. The hard wearing, flush sensors have no moving parts to hang up or wear out and are free of electronics. No electronics means no false alarms and failures due to vibration and shock that can cause errors and fatigue of circuitry.

- Drexelbrook's Cote-Shield™ circuitry ignores coatings
- No moving parts for maintenance free operation
- Immune to vibration
- Heavy duty design

Applications:
- Dry to Moist product

IntelliPoint Blocked Chute Switch - Dry to Moist Product and Coatings
RF Admittance switch for detecting blocked chutes when material can be dry to moist in consistency

The IntelliPoint blocked chute switch from Drexelbrook provides a more robust coating rejection technology compared with the general purpose instrument. With increased moisture levels comes a thicker coating and this calls on a more sophisticated coating rejection circuit. The hard wearing, flush sensors have no moving parts to hang up or wear out and are free of electronics. No electronics means no false alarms and failures due to vibration and shock that can cause errors and fatigue of circuitry.

- Drexelbrook's Intelligent Cote-Shield™ circuitry ignores coatings
- No moving parts for maintenance free operation
- Immune to vibration
- Heavy duty design

Applications:
- Dry to Moist product

Super Cote-Shield™ Blocked Chute Switch - Superior Performance with Wet or Dry Coatings
RF Admittance switch for detecting blocked or plugged chutes where product is prone to dry and wet product

Water and chutes generally combines to creates a tricky environment for sensors. Drexelbrook have a special "Super Cote-Shield™" electronics that pushes the coating rejection of the standard electronics into overdrive. Wet, dry or in between. The Super Cote-Shield™ Blocked Chute switch will adapt automatically to reject the present of coatings that may completely cover the sensors face.

- Special "Super Cote-Shield™ circuitry ignores heavy, wet, coatings
- No moving parts for maintenance free operation
- Immune to vibration
- Heavy duty design

Applications:
- Dry to Wet product
- Ores, coal, wood chips and other granulars and powders.

Blocked Chute Switch - Across Screen detection
Reliable detection of product across wide screens and chutes. Screen blocked chute switch

The Drexelbrook across screen blocked chute system was specially designed with help from leading CHPPs for reliable detection of blockages on vibrating screens and chutes. Unlike competitive products, the patent Cote-Shield™ circuitry enables the device to run maintenance free in the presence of buildup.

Used by major washeries: BHP, Rio Tinto, Anglo America & Vale.

- Drexelbrook's Cote-Shield™ circuitry ignores coatings
- Detects blockage and unwanted buildup across screens
- Adaptable for any screen sizes.
- Can be modified in the field
- No moving parts

Blocked chute Switch - Extra Heavy Duty Insertion type for Wet and Dry Product and Coatings
Heavy duty, 1.75" thick solid rod probe for where a flush detection sensor isn't practical.

Some blocked chute appllications still require an inserton type to get the best results. For those situations Drexelbrook have an extra heavy duy insertion probe that is designed for heavy rock environemnts. Constructed around a solid 1.75" thick 316SS core, the probe flares our the a 2" mounting to support the ncreased loading it may be subjecte to.
