Valuable Electrical Measurements for Your Rail Operation


Ohio Semitronics’ DC/AC voltage, current, and frequency transducers provide highly accurate electrical measurements

in the worlds harshest railway environments.  OSI DC Current transducers are used to monitor critical “on/off” third

rail safety issues.  In addition, OSI provides highly accurate monitoring of DC current and DC voltage for railcars.


With the prevalence of AC outlets on railcars for computer, phone and device charging, OSI transducers are now being

used for AC monitoring to assure inverters are not overloaded.
