Fig. 1—Up to eight rackmountable ISO-DAM8A and Bridge8 modules can be combined in a 

single chassis.

Introduction

Any combination of 

ISO-DAM8A

 or 

Bridge-8

 modules may be combined in the same 

instrument main frame. Bridge-8 includes a differential amplifier featuring high input 

impedance, high common mode rejection of electrical interference and low current 

leakage input terminals. Force, pressure, temperature, displacement, light and other 

physical parameters are readily measured. Thermocouple wire transducers with cold 

junction references for a wide range of temperature monitoring are also available.
