• 3-Phase Voltage Transducers

    Oct 15, 2019
    An overview of the available three-phase voltage transducers from Ohio Semitronics. The 3AVT is an AC average transducer while the 3VTR is an AC RMS voltage transducer. READ MORE
  • What is a Voltage Transducer?

    Sep 25, 2019
    Voltage transducers provide a DC current or voltage output directly proportional to the AC input voltage. AC voltage transducers typically have a transformer input to isolate the transducer from the voltage input. READ MORE
  • Three-Phase Current Monitoring

    Sep 17, 2019
    A custom industrial furnace manufacturer came to OSI for three-phase current monitoring on a furnace. Ohio Semitronics supplied a split-core CTY series Current Transformer (UL listed) in combination with the 3ACT Three-Phase AC Current Transducer, also UL listed, which provides three isolated dc outputs that are directly proportional to the three current inputs.

  • Monitoring DC Current on a Ski Lift with Hall Effect Current Measurement

    Sep 11, 2019
    This ski resorts’ lift utilizes the Ohio Semitronics' CTL-60TS/600 Hall Effect Current Transducer and CTA201 Signal Conditioner for monitoring DC current. The CTA Signal Conditioner provides the excitation current (instrument power) that the CTL Hall Effect sensor requires. READ MORE
  • What is a Watt Transducer?

    Sep 10, 2019
    A watt or power transducer measures true electrical power delivered to a load and converts that measurement to a DC voltage or current signal. To measure power, the watt transducer must monitor both the voltage and current in a circuit. Further, it must be able to accurately determine the phase relationship between the voltage and current.

  • Current Transformer Open Circuit Protection

    Sep 4, 2019
    Older protection designs are expensive and bulky. The OSI OCP-35 is a compact and inexpensive device that limits open-circuit voltages to safe levels of 35V or less. READ MORE
  • What is a Current Transducer?

    Aug 28, 2019
    Current transducers provide a DC current or voltage output directly proportional to the AC input current. AC current transducers typically have a transformer input to isolate the transducer from the current input. Following the transformer are the electronics. There are two types of AC current transducers. READ MORE
  • Military Grade DC Current Monitoring

    Aug 23, 2019
    OSI delivers ruggedized AC and DC current transducers to meet the MIL-SPEC requirements of multiple motorized military vehicle environments. As a result, OSI transducers are available in multiple packages, ranges, and formats. READ MORE
