Type 123 Strain Gauge Amplifier

The Type 123 Stain Gauge Amplifier is compatible with a wide range of strain gauge based sensors including pressure transducers, torque transducers, load cells, and full bridge strain gauges. It provides either a 4-20mA or a 0-10Vdc output for the calibrated range of the sensor. They have been used in a range of applications including weighing systems, torque test rigs and process control systems. 

The Type 123 is designed as a universal amplifier offering input gain ranges for sensors from 0.2mV/V up to 8.0mV/V, The ranges and the zero offset are switch selectable and final calibration is completed using the gain and zero potentiometers 

This range of amplifiers is ideal where the output signal needs to be tailored to a range of different input scaling. 

It is housed in a DIN rail enclosure with all input and output connections clearly marked on the enclosure along with a connection diagram. More detailed information on the product set up is provided on the product information disk with handbook data in five languages. 

In addition to the Type 123 Datum Electronics Ltd manufacture a wide range of load cell indicators and instrumentation, this range includes portable indicators, digital amplifiers and bespoke OEM products.
