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 a variety of bargraph meters and other 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. Our mature products are listed here.

How Does OTEK’s New Technology Differ?
We use ultra-efficient LEDs, nanotechnology ASIC, high-efficiency power management techniques, state of the art software that has been Verified & Validated (SV&V), monolithic transformers for greater accuracy and isolation, our patented loop power technique, signal failure detection-alarming, patented A.C. signal powering technique, 16 bit ASIC DAC with galvanic isolation and optoisolated relay drivers. We also offer OTEK’s exclusive LIFETIME WARRANTY!
All-New Technology products share the same innovative electronic circuit design. The difference between the models is their mechanical features (see Block Diagram and mechanical drawings in our product catalogs). Some devices are displays only, some are single or multi-channel, some can have relays, DACs, ethernet, and flash memory, and some require an external power source. All of our recent products contain New Technology, which consumes less than 1% of the power of comparable digitals (20-100mW for loop/signal powered versions) and approaches the power consumption of analog meters. The upgraded bargraph meters and instrumentation also reduce inefficiency in recording measurements to ensure facilities run optimally.
