The CTX-DC series transmitters convert DC current as high as 400 Amps DC to an isolated 4-20 mA DC output. The design consists of a hall effect sensor and a signal conditioner in one compact split core package. Typical applications include measuring battery loads or battery charging currents, heater loads, or other DC currents, for preventive maintenance, overload protection, or control.
The CTX-DC series transmitters have a built-in hall effect sensor that physically isolates the high DC current from the 4-20 mA output making this product much safer to use than other products or methods. In addition, the non-intrusive design eliminates the insertion loss that exists when DC shunts are used.
