NT Series Transmitters

Otek's new NT Series 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 NTT with its 0-5 amp input, as well as models with optional displays so that the process variable can be both monitored at the panel as well as in the control room.

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.

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).

The UPM-0 is available in either a loop (4-20mA), A.C. or D.C. signal or external power version. The external powered versions can accommodate 4 relays, isolated DAC and power for the analog output (1 per channel).  Other options include >30 signal conditioners and isolated input power options, as well as Ethernet, USB or RS485 and automatic/programmable colors (red/green/yellow) on each character.

You can use the UPM as a DPM (Digital Panel Meter) for analog inputs and/or a universal timer/counter for 15 different functions, including Log & Anti-Log, Datum Zero, Frequency, etc.  In addition, the included match functions (+, -, √, ÷, x) enable it to be used as a scientific counter.

The UPM-0 meets 1/8 DIN mechanical dimensions and is available in Nuclear Class 1E, MIL-Std., and industrial grades.

The UPM Series features 10 different mechanical models, from the flat pack to the explosion proof, and custom orders are welcome!

As with all our products, the UPM comes with a Lifetime Warranty (limited) and has a CMTBF (Calulated Mean Time Between Failure) of 40 years!

The UPM-3 is available in either a loop (4-20mA), A.C. or D.C. signal or external power version. The external powered versions can accommodate 4 relays, isolated DAC and power for the analog output (1 per channel).  Other options include >30 signal conditioners and isolated input power options, as well as Ethernet, USB or RS485 and automatic/programmable colors (red/green/yellow) on each character.  This model is available with either 1, 2 or 3 channels.

This model is available in 1-4 channels and can rival flatscreens with superior HMI/MMI functionality and ease of viewing/analysis of any combination of four variables (i.e. Volts/Amps/Watts/Hertz or temperature/pressure/pH/humidity).  The four channel model can also be sued to monitor/control the product of the other 3 variables, making it ideal for the petrochemical industry. 

The UPM-5 replaces any 3" x 6" barmeter is available in Nuclear Class 1E, MIL-Std., and industrial grades.
