Mea­sure­ment boards & main­frames

The robust RAS­delta main­frame is avail­able with 8 and 16 mea­sure­ment board slots. RAS­delta mea­sure­ment boards can be exchanged, depend­ing on the appli­ca­tion. Due to its com­pact for­mat and low weight, the hard­ware is suit­able for mobile use and easy trans­port. The main­frame is resilient and tem­per­a­ture insen­si­tive, due to the inte­grat­ed fan. Exist­ing sen­sors and elec­tron­ics of the ROTEC RAS FireWire series are com­pat­i­ble with the RAS­delta series. The inte­grat­ed touch pan­el dis­play enables you to oper­ate the sys­tem as a data log­ger with­out a mea­sur­ing lap­top.

Trig­ger board

The pow­er­ful RAS­delta trig­ger board syn­chro­nizes all mea­sure­ment data between chan­nels, acqui­si­tion mod­ules and con­nect­ed front-ends. It is an inte­gral part of the RAS­delta.

Speed board

With the RAS­delta speed board, you record pre­cise, mul­ti-chan­nel and dig­i­tal speed mea­sure­ment data for all trans­mis­sion, con­trol and aux­il­iary dri­ve tests. It is the basis for tor­sion­al vibra­tion analy­sis. The data is acquired via mag­net­ic, angu­lar equidis­tant scan­ning, an incre­men­tal encoder or a laser.

Ana­log board 3,2 MHz

With the RAS­delta ana­log board, you can mea­sure ana­log quan­ti­ties such as air­borne and struc­ture-borne noise, accel­er­a­tion, tem­per­a­ture, dis­place­ment or pres­sure. These quan­ti­ties can be used, for exam­ple, to deter­mine the posi­tion of a sound source or to car­ry out detailed valve train or cylin­der pres­sure inves­ti­ga­tions. The ana­log mea­sure­ment data is acquired by equidis­tant sam­pling.

DMS board

The RAS­delta strain gauge board is an inte­grat­ed two-chan­nel DC volt­age ampli­fi­er for sig­nal acqui­si­tion from strain gauge-based, piezore­sis­tive, mag­ne­tore­sis­tive or poten­tio­met­ric trans­duc­ers. These include force, torque, pres­sure, dis­place­ment and angle sen­sors or scales. A big advan­tage of the board is that you can do with­out addi­tion­al mea­sur­ing ampli­fiers.

Clus­ter

You can mod­u­lar­ly expand the num­ber of chan­nels by cou­pling the RAS­delta front-ends to each oth­er via the Eth­er­net and Sync inter­faces. One of the front ends acts as mas­ter card and syn­chro­nizes the oth­er devices in the clus­ter. The ROTEC soft­ware rec­og­nizes the RAS­delta clus­ter as an extend­ed front end with addi­tion­al slots.

Data log­ger

With the addi­tion­al data log­ger mod­ule, you can con­vert your RAS­delta 08 or 16 front-end to a data log­ger for mobile use such as in motor vehi­cles, on motor­cy­cles, in rac­ings or for appli­ca­tions at sea. The RAS­delta runs in data log­ger mode with­out a mea­sur­ing lap­top, where­by all func­tions for oper­at­ing the sys­tem can be exe­cut­ed direct­ly at the RAS­delta front end. Touch oper­a­tions on the dis­play enables mea­sure­ments to be con­fig­ured and car­ried out. All con­fig­u­ra­tion and mea­sure­ment data are stored on a micro SD card with USB adapter and can lat­er be trans­ferred to a PC for eval­u­a­tion.
