SD01A Zener Barrier Set for Intrinsically Safe Measurement Circuits in Hazardous Areas

HBM has chosen the SD01A Zener barrier set especially for use with strain-gauge (SG) transducers connected to carrier-frequency and DC amplifiers that are balanced to ground. In instrumentation and control engineering, Zener barriers are used to process small voltages and currents. The Zener barriers contain intrinsically safe circuits which serve to operate intrinsically safe field devices (e.g. load cells or force transducers) in areas with potentially explosive atmospheres (hazardous areas).

  • Suited to be used with SG transducers in full bridge circuit, 6-wire configuration
  • Usable with HBM electronics PMX, digiCLIP, MGCplus, PME, MVD, Clip, and RM4220
  • EC type-examination certificate BAS01ATEX7005 (Ex II (1) GD, [EEx ia] IIC)

 

 

Reliable measurement

  • Three optimized safety barriers for intrinsically safe installation, for use with all common SG transducers such as force sensors and load cells
  • Protective separation from Zone 2 non-hazardous and hazardous areas in accordance with Statement of Conformity TÜV 99 ATEX 1484 X II 3G Ex nA IIC T4 Gc

Reliable use, due to certified EC type-examination certificate

Safe handling

  • For measuring amplifiers with carrier-frequency or DC sensor supply balanced to ground
  • Usable with HBM electronics PMX, digiCLIP, MGCplus, PME, MVD, Clip, and RM4220
  • Detailed documentation including circuitry and wiring diagrams

Specially matched to HBM sensors and HBM measuring amplifiers 

 

 

Tried and tested in use many times over

  • Standardized, tried and tested installation on DIN rails according to DIN 50022 in the control cabinet
  • EC type-examination certificate BAS01ATEX7005 (Ex II (1) GD, [EEx ia] IIC)

Suited to be used in many applications in process and factory Automation
