Otek offers a variety of 4-20mA transmitters, re-transmitters, isolators and calibrators. We have dozens of signal conditioners that can be used to excite the input from your transmitter and convert it to a current loop or voltage. Otek offers models that can be powered from the input signal such as the CTT with its 0-5 amp input. As well as offers models with optional displays so that the process variable can be both monitored at the panel as well as in the control room.
