PICOSTRAIN® - Load Cell Simulator
ALCS-350 - High Precision Load Cell Simulator
The ALCS-350 is a high-precision load cell simulator, based on accurate resistor networks with 350 Ohm base resistance. For this reason it is suited for all kinds of weighing electronics for strain gauge load cells, whatever excitation principle is used.
Test, Qualify and Batch Weighing Instruments
The simulator is connectable to electronics with DC voltage excitation and AC voltage excitation. Of course it can be used with acam's PICOSTRAIN devices. The ALCS-350 simulates two separate half-bridges or one full-bridge. The full-bridge can be connected in a Wheatstone or PICOSTRAIN bridge. It is ideal for testing, qualifying and batching weighing instruments.
The simulator output is adjustable from 0 to 3 mV/V in steps of 0.1 mV/V with full-bridges (or 0.2 mV/V with half-bridges) by setting appropriate switches.
Switch Controlled Load Cell Simulator
The simulator has 3 different interfaces for switch control. Eight mechanical switches on the top of the housing form the human interface. However, the simulator is also controllable by means of a PC connected via alternative RS232 or USB interfaces. In these 2 options, the ALCS-350 is a perfect tool for systematic, PC-controlled testing and batch control. It can be used in the laboratory as well as in production testing.
Precise Analysis of Converter Electronics Linearity
The ALCS-350 performs with very high precision and a high temperature stability. In particular it can generate a very high precision analysis of converter electronics linearity due to the internal structure of the simulator. The ALCS-350 comes with a software which has a graphical user interface that copies the mechanical switches and offers user-friendly device control. Simple ASCII code commands allow the ALCS-350 to be embedded in an automated test system.
The system is powered by an external 9 to 16 V supply. If the USB interface is used, the interface powers the system by itself.
