    • 品牌: TESEO

      The fiber optic digital voltmeter system is used for accurate DC voltage measurement under conditions such as electromagnetic interference, noise and extremely high voltage. The plug-in system consists of four channels for host-adaptive, four battery-powered, muting sensors, each connected to the base plug-in via a fiber optic communication line, with separate battery power supplies.

      Basic unit plug-in: ODVM301 plug-in system is a digital voltmeter with 1mV resolution and +/-32V full scale. Measurements are controlled by remote satellites via fiber optic links, and the ODVM301P offers four optional electronic receivers that can be connected to four satellite units. The MOCS host can install up to 12 ODVM301P basic plug-ins, a total of 48 independent fiber channels. Measurements for each channel are displayed on the main unit's LCD as 3 prominent decimal digits. Also, make it readable via built-in RS232 and GPIB interfaces. The readings are displayed at a rate of one every two seconds.

      Satellite unit: ODVM301S satellite is small in size and powered by batteries, and can be tested in environments with high electromagnetic field characteristics. It can withstand electromagnetic fields up to 200V/m within 1kHz-18GHz, and can be used in various environments without significant change in performance. Continuous operation for 24 hours, with battery charging. Equipped with a switch to control the battery status. 1M ohm impedance differential input, auto-calibration technology, digital filtering to ensure long-term accurate operation and noise shielding. Input resistance cables can be used to ensure that the device under test is not affected by the environment and electromagnetic fields, and in general, a disturbance-free test can be presented. Resistive cable lengths are optional, terminations are optional, and internal drivers are optional to measure high voltage signals.

      Each plug-in unit has a CB4 battery powered charger, except the base plug-in and satellite units. There are also fiber optic cables up to 1km long, and a solid reeling frame. It can be equipped with fiber optic cable feedthrough.
