Split-core transformers are ideal for installation on existing electrical wiring by snapping around the conductor. The SCT series have one of the highest industry standards for interleaving joints and the self-locking mechanism.
The OSM-RCT/RCS-1800 series flexible RopeCT current sensors measure AC current up to 5,000 Amps. The coil opens at the connector junction and can be installed on an existing cable or buss-bar in a matter of seconds.
A selection of economical AC and DC power supplies specially chosen to accompany the products sold by Open Source Meter. Complete your project with the right power for the job.
Meters Loop and Voltage Powered - Select a meter from a variety of colors and inputs. Tip: Combine with our 4-20mA transducer and one of our 0.333v current transformers for an economical current meter!
Solid-core transformers are the perfect choice to save money in applications where the transformer can be slipped over the end of the conductor. The UCT series offer great value for a +/- 1% accurate transformer.
Our transducers allow you to connect a low cost 4-20mA loop meter, loop powered alarm, relay switch, or other loop powered device to one of our 0.333VAC output current transformers.
Our transducers allow you to output a analog voltage signal to alarms, relay switch, or other voltage input devices to one of our 0.333VAC output current transformers or other sensors.
This light compact field calibrator is a handy device for calibrating process loop meters among other devices. Provides a 1% accurate calibration. Need a one time calibration? Ask about our free loop meter calibrating service.
