概述
称重仪表也叫称重显示控制仪表，是将称重传感器信号（或再通过重量变送器）转换为重量数字显示，并可对重量数据进行储存、统计、打印的电子设备，常用于工农业生产中的自动化配料，称重，以提高生产效率。
美国Transducer Techniques SSI是一款智能插拔式TEDS IEEE 1451.4仪表，连接称重传感器或者扭矩传感器TEDS接头，可自动校准。SSI内置双报警继电器，伴随LED灯和声响指示。自带USB接口，将数据采集给PC端。
The SSI is a Plug & Play Smart TEDS IEEE 1451.4 compliant portable handheld Load Cell Indicator. Just plug in a TEDS compatible Load Cell or Torque Sensor and the SSI will automatically selfcalibrate. When used with a non-TEDS Load Cell or Torque Sensor, the SSI can be set up by simple front panel push buttons. The SSI can be scaled to a full 5 digit display from 0 to 99,999 counts to read directly in engineering units such as grams, ounces, pounds, inch pounds, etc. The SSI also has a Units key for automatic conversion of readings for load, torque and pressure. The SSI has an ultra-fast signal-sampling rate of 15,360 samples/second for true peak and/or valley testing capability. Auto-tare allows the meter to be set to zero for any input signal level. The SSI also features a USB port for data logging to a PC. You can also log data to the SSI’s internal memory storing up to 8,000 time and date stamped readings. The SSI also features 2 built-in solidstate alarm relays with LED and audible indicators. The SSI will operate up to 65 hours on a single charge or use the included battery charger for applications where the SSI is mounted permanently.
