BRAUN INSTRUMENT Sensors

Speed Sensors

Each application calls for a sensor that is suitable to its needs. To meet the demand for optimum performance a broad choice in function principle and design is required. 

We provide this. 

 

Non-Contact Sensors

No moving parts = no wear, no maintenance.Easy to install. Saving cost and space.  

 

Sensors touching the target

Solving special problems

 

Non-Contact Sensors


Differential-Hall-Effect Series A5S...
Your first choice for permanent installation. Detecting small and large steel profiles (gear wheels, slots, holes). Outstanding performance under hard ambient conditions: Speed range 0... 25,000 pulses per sec, equally high and powerful output over  theentire range, adequate for transmission over more than 500 meters. Level approximately that of supply voltage. Profile size down to gear m 0,8 (pitch 32), slot or hole width down to 3 mm. Gap (clearance) to target nearly up to 4 mm. Their differential principle fights the influence of other magnetic fields and machine vibration. Sealed (>200 bar) stainless steel enclosure with smooth or threaded shaft 5/8UNF, or M12, M14, M18, or M22, length as option

Temperature -40°C ...+125°C ( -40 ... +255 °F). Connection via tight plug or firm cable.

A5S40 …A5S43

double trace frequency output, for external direction evaluation with failure detection. Typical: monitored direction detection

requires gear size > m2 (pitch < 12), slot width > 4 mm

 

 

Opto-electronic Sensor Series A1S... 


Applicable to all objects, including plastic parts (fan blades, for instance). A  not profiled target (smooth shaft, for instance) will be easily marked  by a paint dot or by our adhesive reflective tape. Local environment should be kept clean. Signal conditioning in evaluation unit recommended, as provided by our C118, C156, or E1519 units.
Speed range 0/10 ...20,000 pulses per sec. Connection detachable with plug, or tight by firm cable. Signal transmission up to 10 meters (as standard), A1S40 up to 100 meters.   Specific application characteristics of A1S... series: 

 

Model No.

Application Characteristics

A1S30... A1S36..

easy handling, the favourite for variable use. Scanning distance 1...2 cm (depending on reflection).Sensor shaft 8 mm Ǿ, length 35 or 95 mm. Supply typically by evaluating unit. 

A1S37P

Laser type reflection sensor with scanning distance up to 2 meters. Laser beam < 3 mm in Ǿ, thereby sharp resolution. Requires marking with reflective tape U1A006.

A1S40

Infrared reflection sensor. Cylindrical enclosure with mounting thread M30. Scanning distance up to 50 cm. Optional fibre glass adapters for extreme conditions (temperature up to 300 °C, for instance).  

 

Proximity Type sensor series A4S.... 

 

Applicable to larger sized profiles of steel or non-ferrous material. Allowing a large gap(clearance) between sensor and target: useful at a center displaced wheel, or if particles have to pass between sensor and target. Range from zero up to medium speed. Typical feeder belts, blades.  Characteristics vary widely between different models.

 

Magnetic pick-up sensor series A2S... 

 

Detecting speed of rotating steel profiles, specifically at high speed, and under high temperature (turbines, turbo-blowers, for instance). Also, the alternating magnetic field around transformers, ignition coils, or rotating magnetic parts. Output signal varies with frequency and gap, therefore requiring high sensitivity of the receiver input, or a local pre-amplifier.
Not for low speed applications.These sensors do not require supply. Various design models available. 

  

 

Sensors Touching the Target


Wheel Pulse Transmitters
Detecting speed and material length when run on a web, or on the surface of a cylinder.Specifically used with plastic and metallic foils, and with paper and textile machines. Speed range up to 3000 m/min. Resolution up to 1 pulse per millimeter. All models have a high output allowing signal transmission over 100 meters.

BRAUN INSTRUMENT High Safety Speed Monitoring Systems

Speed Monitoring Systems with Enhanced Safety,
for turbines, pumps, motors, as typically found in power plants.

 

A system intended to protect persons and assets against overspeed danger must be equipped accordingly. This concerns its parts, but also the redundancy of its structure. We offer different gradations to regard the individual requirements of the application.

Safety Aspects

Redundancy by the number of participating channels

With one channel only, safety is determined by the equipment of this one element. Sensor monitoring, plausibility (function presence) check, and failure signal are indispensable hereto. With a 2-channel redundancy 2 such units operate in parallel. Their outputs are tied together, but this requires a pre-decision what to do in case of a discrepancy, whether trip or not. The 3-channel redundancy allows the majority to determine the action. This not only enhances safety in event of danger but also increases security against false alarm and thereby promotes machine availability.  True functional tests are possible during operation. The E16 design may do this automatically, saving cost of maintenance.                          

 

 

 

D521

 

 

E16

Intrinsic Self Tests

A plausibility test reports any channel performance failure. The sensor monitoring facility detects a peripheral failure at an early stage. Regularly repeated response tests by an independent Test Generator, as possible with the E16 ensure the maximum in safety.

 

Test Routine

E16 performs  these tests automatically and regularly under full load. The user is exempted from the otherwise obligatory manual tests. The test routine of E16x3 fulfils all requirements  up to SIL3 of IEC 61508.

 

Failure Signal

Indispensable for true safety, by calling for the necessary measures, in time

 

 

Certification compliant

Series E16x3 for SIL3 according to IEC61508 (without restriction) and compliant with API 670.

Series E16x4  compliant with API 670.
