four-channel bridge amplifier, BRAM-4B, features low-noise, low-drift, differential
inputs, multi-gain and filter selection, and low-cost. It can be utilized
for sensitive measurement and detection of force (i-FOT), displacement (i-DIST),
pressure (i-PRT), flow, pulse (i-PLT), temperature (i-TEMT), humidity, gas,
and optical light, etc., from 0 Hz up, using transducers or sensors.
The BRAM4's stand-alone design
and its high input impedance allows it to be used conveniently with our
sensors and/or transducers or most other active/passive transducers via
easy adaptation. It is compatible with our USB-based data acquisition
systems as well as the data recording/acquisition systems from other manufacturers'.
For use with other manufacturers' transducers or sensors, an DIN8F adapting
connector is needed.

The i-FOT series isometric force transducers have excellent
linearity, high sensitivity and stability, with wide dynamic ranging from
0.5mg-10g (i-FOT10) to 150mg-2000grams (i-FOT2000).
The i-FOT transducers feature innovative designs resulting in consistent
point of force application and easy mounting access. Compared with traditional
design where
They feature a protective mount sleeve (Ø=0.50'' or 12.7mm) and
a DIN-8 connector directly compatible with our BRAM4 Bridge Amp and data
acquisition system, ThinkWave 1600-4/8.
