12.2 ESD142 amplifier + Strain Gauge
12.2.1 ESD142 Description
The ESD142 is a load sensor amplifier, which is used to amplify the load signal coming from a strain-
gauge type of load sensor to a suitable voltage level for the hoist-monitoring unit.
At the moment there are two versions, the ESD 142 and the ESD142/1. The basic model is the ESD 142,
which is used with full-bridge load sensors. The ESD 142/1 is the modified version, which is suitable for
half-bridge load sensors.
The units are adjusted by means of two trimmers, named “ZERO” and “GAIN”. With the ZERO-trimmer,
the 0% load adjustment is biased. The GAIN-trimmer is used to adjust the amplification factor in order to
reach the required output voltage at full load.
There are two LED’s, marked as “0%” and “100%”, indicating the status of the load.
