PXI Strain Emulator Module 40-265-104 3k Ohm 4 Channel

40-265系列包含6、4或2通道模塊（此版本為4通道3kΩ），它們模擬一系列應變儀的操作，使其非常適合測試應變計和各種工業控制系統。該範圍提供了一種簡單的方法，用性能優異的低成本模擬器替換內部開發的傳感器。40-265使用與真實應變計所基於的相同的電阻橋技術，從而確保在所有條件下均能進行精確仿真。

Each emulator channel includes a separate excitation voltage input and a bridge output. The excitation voltage port can be driven by either AC or DC power. The bridge circuit consists of three fixed resistors and a fourth programmable resistor, which can be adjusted over a narrow range of resistors for good regulation and excellent accuracy. The range of adjustment provided is sufficient to simulate quarter, half or full bridge circuits. Standard bridge impedances are 350Ω, 1kΩ, 1.5kΩ, 2kΩ and 3kΩ.

These modules are extremely easy to use and variable resistor elements can be programmed with simple resistance calls. The modules provide the user with the required resistance values for balancing the bridge, and the simulator's resistance values can be changed above or below these values to simulate the expansion and compression of the strain gauge resistor.
