product details
SPMK271 multi-channel pressure data acquisition device supports parallel operation of 48 channels. Each channel can output high-precision excitation current or voltage and complete high-precision measurements. Combined with intelligent pressure controllers and upper computer data acquisition and control software, it can achieve fully automatic collection and analysis of various signal types such as current, voltage, on-off, resistance, etc. Each acquisition channel of the port includes excitation input and signal acquisition, and the channels are isolated. Adopting modular design, 8 boards can be placed, and each board can be configured with 6 measurement channels. Multiple projects are measured and displayed simultaneously; Multi channel parallel display on LCD screen. The board can be increased or decreased according to the actual needs of the customer. It is convenient for customers to calibrate a large number of pressure instruments with various signal types, making it easy and convenient. It can achieve fully automatic data collection and analysis, making it an ideal choice for pressure instrument production and testing users.
main features
◆Can complete current, voltage, frequency, pulse, on-off, resistance, temperature(PT100)Measurement of various signals;
◆support48Parallel channels are used to collect various electrical signal data simultaneously;
◆Plug in card design, each card is independent of each other and does not affect each other; Users can add or remove boards according to their own needs;
