產(chǎn)品簡介
稱重變送器也叫做重量變送器，是一種將物理量變換成電信號，將毫伏信號輸出的傳感器經(jīng)隔離放大轉(zhuǎn)換成標準直流信號的變送器。
稱重變送器在工業(yè)稱重過程中常用的一種變送器，廣泛應用于數(shù)據(jù)采集、信號傳輸轉(zhuǎn)換和集散稱重控制系統(tǒng)和配料系統(tǒng)，主要應用于水泥、混凝土、玻璃、造紙、塑膠、化工、冶金、有色、棉紡、試驗機等行業(yè)稱重式料位、重量負荷、張力、拉壓力信號的變送、顯示、檢測等。
美國Transducer Techniques SST-HV是一款智能插拔式TEDS IEEE 1451.4變送器，連接稱重傳感器或者扭矩傳感器TEDS接頭，可自動校準。SST-HV通過RS232端口，將數(shù)據(jù)采集給PC端。
The Transducer SST-HV is a Plug & Play Smart TEDS IEEE 1451.4 compliant Transmitter. Just plug in a TEDS compatible Load Cell or Torque Sensor and the SST-HV will automatically self-calibrate. When used with a non-TEDS Load Cell or Torque Sensor, the SST-LV Transmitter is easily programmed using a PC with an RS232 port and Instrument Setup (IS) software, which provides a graphical user interface. The SST-HV may be powered from 95-240 Vac ±10%. The SST-HV has an Isolated transducer excitation output that is selectable between 5Vdc or 10Vdc. There are Dual solid state relays and an Isolated 4-20 mA, 0-20 mA or 0-10V analog output. There are three Isolated serial data transmitter output ( RS232 , Half-duplex RS485, full-duplex RS485 ) and three serial protocols that are software selectable (Modbus RTU, Modbus ASCII and Custom ASCII).
Isolation to 250V rms is provided for power, signal input, analog output, relay outputs, and communications. Isolation adds safety and avoids possible ground loops. The transducer excitation output is isolated to 50V from signal ground
CE認證
Accuracy of 0.01% of full scale ± 1 count.
Update rate to 60/sec in 60 Hz noise environments or 50/sec in 50 Hz noise environments.
Full-scale range from 20.000 mV full scale (1 μV resolution) to 500.00 mV full scale (10 μV resolution).
Isolated transducer excitation output. 5V at 100mA or 10V at 120mA as selected by TEDS. In non-TEDS operation, the excitation is always 10V.
Isolated 4-20 mA, 0-20 mA or 0-10V analog output.
Isolated serial data transmitter output. The transmitter serial port is default jumpered for RS232 or full-duplex RS485 (same jumper settings).
Isolation to 250V rms is provided for power, signal input, analog output, relay outputs, and com-munications.
Internal jumpers are used to select the signal range, communication type, and exci?tation level.
Transmitter setup is via serial connection to a PC using MS Windows based Instrument Setup Software plus TEDS IEEE 1451.4 when detected.
