1.  Safety Instructions 

 

 

ATTENTION!  

Any non-compliance with these safety precautions may result in severe damage to property and health!.

 

 

 

ATTENTION!  

These Operating Instructions explain the installation, bringing into service, and operation of the type BS 
805.0x  amplifier.  It  is  assumed  that  every  action  is  taken  by  qualified  staff  only  who  have  adequate 
knowledge in the fields of measuring and control engineering. 
The  equipment  must  be  installed  and  attached  under  adherence  to  of  the  current  DIN  and  VDE 
standards. 

 

 

ATTENTION!  

The type 

BS 805.01

 Strain-Gauge amplifier has been designed to the purpose of amplifying the output 

signals of sensors with

 metal-foil strain gauges

, preferably force transducers. 

The type 

BS 805.02

 has been designed to the purpose of amplifying the output signals of sensors with 

standard signal 4-20mA

, preferably force transducers. 

Any other application is regarded contrary to intended usage.  
The 

BS  805.0x

  may  not  be  used  as  exclusive  means  for  the  prevention  of  dangerous  conditions  at 

machines and plants. 
Make sure that any erroneous setting or malfunction of the unit or its break-down cannot cause damage 
or be a risk to the staff or other persons.
