Data Translation Announces High Isolation MEASURpoint Instruments

November 1, 2011. Data Translation Inc. has announced the addition of two new ultra high-isolation Ethernet measurement instruments to its popular MEASURpoint™ product line. The ISO-Channel™ design provides up to ±3500-V high-voltage rejection using galvanic isolation techniques to preserve small signals generated from thermocouples, RTDs, and other sensitive sensors in harsh, high voltage noise environments. Target markets for the instruments include wind, gas, battery, and solar-energy installations, where high-isolation protection is required to ensure data-acquisition integrity in noisy and often remote settings.

Key features include high isolation to earth ground (±1400V continuously or 2500V for transients on Model DT8875 or ±3500V continuously or 5000V for transients on Model DT8876); channel-to-channel Isolation of 2800V (DT8875) or 7000V (DT8876); a high stability, 24-bit resolution delta-sigma ADC per channel; and up to 40 simultaneous differential inputs (DT8875) or 20 simultaneous differential inputs (DT8876). The instruments support thermocouples and RTDs; accuracy is ±0.24°C with type B, E, J, K, N, R, S, and T thermocouples. The instruments also support 4-wire, 3-wire, or 2-wire PT100, PT500, PT1000 RTDs with accuracy to ±0.03°C. Sample rate is up to 10 Hz per channel. The instruments come with MEASURpoint Framework and web-based applications.
