DPM-3 数字仪表

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 DPM-3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。

The DPM-3 is a smart Plug & Play TEDS IEEE 1451.4 compliant Digital Panel Mount Load Cell meter. Just plug in a TEDS compatible Load Cell or Torque Sensor and the DPM-3 will automatically self-calibrate. When used with a non-TEDS Load Cell or Torque Sensor, the DPM-3 can be set up by simple front panel push buttons. The DPM-3 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, etc. The DPM-3 samples 60 readings per second (50 for 50Hz operation) for fast control response and true peak/valley reading capability. The meter has an adaptive digital filter that can automatically select the best time constant for minimum noise, yet respond rapidly to an actual change in signal level. The peak and valley values can be displayed by a push of a button on the front panel. Auto-tare allows the meter to be set to zero for any input signal level. Available options include dual relays, analog output, serial communications, and low voltage power supply.
