NTT - MANUAL OR PAC/SCADA 4-20mA NEW TECHNOLOGY TRANSMITTER

Product Description:

OTEK’s New Technology Transmitter (NTT) was designed to replace old “thumbwheel controllers.”   These were popular in 1960 nuclear installations to allow operators to manually control a variety of current loop (4-20mA) driven loads.  These controllers were used to control valves, motors, flood gates, etc., in conjunction with and/or in place of automatic controls.

The NTT is a form and function meter that is compatible with OTEK’s WES-1 controller, and has the added features of OTEK’s patent pending New Technology (also used in the LPD Series).  The New Technology features 100% loop powered bar-digital automatic tricolor display, automatic signal/load failure detect and reporting, single ASIC/nanotechnology self diagnostics & reporting, µC and serial input control of 4-20mA output (or manual control via a 270º front panel potentiometer for high reliability, stability and resolution).

Additional Information:

OTEK’s 420 (2.5"W x 4.5"H x .75"D) was developed by popular demand for a low cost, no frills field calibrator with 3 1/2 LED digital display for any device requiring the popular 4-20mA current loop signal.

The 420 also measures your current loop powerless (no power required) so you can calibrate your transmitter.
