Theory Of Load Cell; Introduction To Dvp02Lc-Sl - Delta DVP02LC-SL Operation Manual

Theory of Load Cell

When metallic materials encounter a pulling force or tension, they will become thin, and the electrical
resistance will increase. In other words, when the materials are compressed, the resistance will
become small. The strain meter adopting this theory is called a load cell. Such sensing device is able to
convert physical pressure changes into output electrical signals and is widely used in loading, tension
and pressure conversion applications.

Introduction to DVP02LC-SL

1. Thank you for choosing Delta DVP02LC-SL load cell module. DVO02LC-SL provides 24-bit
resolution applicable for 4-wire or 6-wire load cells with various eigenvalues. Therefore, the
response time can be adjusted in coordination with each other according to users' needs. On this
basis, the market requirements on weight measurement can easily be met.
2. To ensure correct installation and operation of DVP02LC-SL, please read this operation manual
carefully before using it. This operation manual only provides introductory information on
DVP02LC-SL. For more detailed information on the theory of load cell, please refer to relevant
references of literature.
3. The DVP02LC-SL load cell module is able to read/write data by using FROM/TO instructions
through the DVP series PLC MPU
Note: The MPU (main processing unit) refers to PLC compatible with left-side extension, e.g. DVP-SV,
DVP-EH2-L, DVP-SA2, DVP-SX2 series PLC.
