A5S1DD0

Sensor A5S1DD0 for detection of rotational speed in Hazardous Areas Zone 0 or 1 and highest safety requirements up to SIL3

The BRAUN Speed Sensors Series A5S1 are TÜV certified for SIL3 acc. IEC 61508:2010 and therefore meet the high SIL3 standards. To meet the specific requirements of hazardous areas (Ex Zone 0 or 1), we provide these specialized types which are certified for ATEX, UKEX, IECEx, as well as for other international standards such as UL/CSA. A5S1 sensors, in conjunction with our Isolating Barrier D461, provide an intrinsically safe implementation to meet these specific requirements.

The correct choice of sensor is always a prerequisite to achieving a successful solution. Therefore, BRAUN A5S1 sensors base on the proven Differential-Hall-Effect principle. Their low end of 0 Hz allows monitoring the machine down to zero speed. They are contact-free, wear-free, maintenance-free, and unsusceptible versus external magnetic stray fields and machine vibration. These characteristics make the series of A5S1 sensors especially suited for all applications where high accuracy and reliability are at a premium.
In contrast, other sensors like magnet-inductive or static Hall-sensors do not meet these demands.

Each sensor in the series is available in various lengths and diameters and comes with a choice of connections. However, functionally all sensors have the same characteristics.
The stainless steel sensor housing is sealed at the front and is pressure-resistant (>200bar). A flat shaft is available or with a screw-in thread M12x1, M14x1, M14x1,5, M16x1, M16x1,5, M18x1, M18x1,5, M22x1, 5/8-18UNF-2A. Customized dimensions and thread specifications are possible.

Key Features

  • SIL3/IEC 61508:2010 certified by TÜV
  • Detection of rotational speed in Hazardous Areas Zone 0 or 1
  • Speed range from 0 Hz to 25 kHz
  • Single Channel,

  • Temperature range -40…+125 °C (-40…+255 °F)
  • Differential principle diminishes the influence of external magnetic stray fields and machine vibration
  • Sealed stainless steel enclosure > 200 bar pressure to the sensor tip
  • Available for connection via tight plug, or with fixed Teflon® cable
  • Powerful square wave output signal equally high over the entire speed range
  • Sensor short circuit proof and protected versus polarity error
  • Accepting fine and coarse profiles, as gear wheels, slots, cams, holes in any ferrous material
  • Requires Isolating Barrier D461
  • For installation in hazardous areas as intrinsically safe operating resource
    • ATEX, UKEX, IECEx certified for Ex ia IIC T4/T6 Ga
    • QPS / QPSus certified for Class I, Div 1, Groups A, B, C, D according to UL and CSA standards

Benefits

  • Contact-free with a large air gap, so the potential for damage is eliminated
  • Wear-free due to its unique design principle
  • Maintenance-free during Lifetime, therefore minimized TCO
  • Unsusceptible versus external magnetic stray fields and machine vibration
  • Operates down to zero speed
  • Cannot be damaged by faulty wiring

A5S1DS4

Sensor A5S1DS4 for detection of rotational speed and direction of rotation with two phase-shifted speed signals in Hazardous Areas Zone 0 or 1 and highest safety requirements up to SIL3

The BRAUN Speed Sensors Series A5S1 are TÜV certified for SIL3 acc. IEC 61508:2010 and therefore meet the high SIL3 standards. To meet the specific requirements of hazardous areas (Ex Zone 0 or 1), we provide these specialized types which are certified for ATEX, UKEX, IECEx, as well as for other international standards such as UL/CSA. A5S1 sensors, in conjunction with our Isolating Barrier D461, provide an intrinsically safe implementation to meet these specific requirements.

The correct choice of sensor is always a prerequisite to achieving a successful solution. Therefore BRAUN A5S1 sensors base on the proven Differential-Hall-Effect principle. Their low end of 0 Hz allows monitoring the machine down to zero speed. They are contact-free, wear-free, maintenance-free, and unsusceptible versus external magnetic stray fields and machine vibration. These characteristics make the series of A5S1 sensors especially suited for all applications where high accuracy and reliability are at a premium.
In contrast, other sensors like magnet-inductive or static Hall-sensors do not meet these demands.

Each sensor in the series is available in various lengths and diameters and comes with a choice of connections. However, functionally all sensors have the same characteristics.
The stainless steel sensor housing is sealed at the front and is pressure-resistant (>200bar). A flat shaft is available or with a screw-in thread M12x1, M14x1, M14x1,5, M16x1, M16x1,5, M18x1, M18x1,5, M22x1, 5/8-18UNF-2A. Customized dimensions and thread specifications are possible.

D461R1

Isolating Barrier for A5S1… Ex ia sensors in Hazardous Areas Zone 0-1

The BRAUN Isolating Barrier D461R1 is ATEX, UKEX, IECEx and KCs certified and approved for other international standards such as UL/CSA. So, it meets the particular requirements of explosion protection areas (zone 0 or 1).
In conjunction with one of our sensors series A5S1…, the Isolating Barrier establishes a highly efficient system to detect speed and/or direction in a hazardous area to supply high-level output signals to the periphery.
The barrier provides an intrinsic safety circuit for the sensor and its cabling and, therefore, does not require Ex d measures.

The signal input is isolated from the signal output. Both are isolated versus the power supply. The signal output of the unit repeats the input pulse signals with push/pull characteristics.
The signal input matches the specifications of the speed sensor series A5S1…, which are approved as intrinsic safety devices to be installed in hazardous area zone 0 or 1.
The sensor supply circuit is monitored, and a fault is signalized.

The barrier unit D461R1 must be installed in a safe (non-hazardous) area or within an explosion-proof (Ex d) enclosure.

Key Features

  • For use in connection with A5S1… Ex ia series sensors
  • Establishes a highly efficient system to detect rotational speed (and direction of rotation) in areas of explosion risk
  • Provides intrinsic safety for the sensor and its cabling
  • Comprehends sensor supply and signal connection
  • Sensor supply monitoring
  • Free-floating, therefore maximum immunity versus EMI
  • Push/pull signal output to subsequent monitors
  • Implementation outside the hazardous area, resp. protected by a pressure-resistant encapsulated housing
  • Certification for
    • ATEX as Ex ia Ga IIC
    • UKEX as Ex ia Ga IIC
    • IECEx as Ex ia Ga IIC
    • KCs as Ex ia Ga IIC
    • QPS / QPSus as Ex ia Ga IIC for Class I, Div 1, Groups A, B, C, D according to UL and CSA standards
