4-20mA LED Panel Meters

 

Otek possibly offers the most comprehensive selection of Bargraph Indicators and Digital Panel Meters with 4-20mA input and output options.  An entire series of LED displays are available in “Powerless” selection (4-20mA Loop Powered).

Many of these 4-20mA instruments are provided in industry-standard size housings for easy (form and function) replacement of obsolete analog Bargraph Indicators or Digital Panel Meters.

The modular design of Otek products allows a high degree of product customization recognized by customers worldwide.

LPI Loop-Powered Isolator

OTEK’s Model LPI does not use transformers that provides up to 1KV isolation and reflect "Choppers" noise on the transmitter's line.

The World's largest manufacturer of  Loop Powered Instruments introduces its New Model LPI (Pat. Pending). Unlike other products in the market, the LPI does not use transformers that provides up to 1KV isolation and reflect "Choppers" noise on the transmitter's line. OTEK's LPI has 3KV isolation and uses optoisolators. OTEK's new LPI uses a patent pending design with ultra low quiecent current allowing the LPI to use a high efficiency High Isolation Optocoupler up to 5KVDC but down rated to 3KVDC/RMS. The rest is "cookbook" recipe. Two models are available; the "In-Line" module is for inserting it in series with existing loops and the DIN-Rail for DIN rail mount. Use the LPI as: Isolator, Repeater, Converter (4-20 to 1-5V or 0-10V to 4-20mA & 0-10V, 0-2KHz to 4-20mA, 4-20mA to 2KHz, or 0-10V to 0-2KHz), Buffer, Scaler, etc. The LPI has a Green LED at the input and a Red LED at the output so you can "see" the loop. Their intensity is directly proportional to the input-output current. 

UPM-0: Universal DPM-Counter-Timer

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!

UPM-3: Universal DPM-Counter-Timer

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.

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-3 meets 4" ANSI mechanical dimensions and is available in Nuclear Class 1E, MIL-Std., and industrial grades.

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, 3 or 4 channels.

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.

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" x 3" barmeter and is available in Nuclear Class 1E, MIL-Std., and industrial grades.  It is ideal for displaying/controlling multiple variables such as:  V, A, W & Hz or for triple redundant control.

UPM-F: Universal DPM-Counter-Timer

The UPM-F is a single channel compact unit (2"x3"x1/2") that needs no panel cut-out, only a 1/2" hole for mounting.  The flat pack case model is for display only, and offers no controlling or analog outputs.   

The UPM-F is available in either a loop (4-20mA), A.C. or D.C. signal or external power version. The external powered version offers >30 signal conditioners with non-isolated power input options (Non-Isolated 5VDC or 7-32VDC).  This compact unit also features automatic/programmable colors (red/green/yellow) on each character.

UPM-L: Loop, Signal or Externally Powered Universal Panel Meter

The Universal Panel Meter (UPM) series combines over 40 years of experience with the latest ASIC uC and ultra-efficient multicolor alphanumeric LED technology to bring you into the 21st century. The UPM external power series features over 30 signal conditioners which are installed via plug-in for ease of interchange in the field.  The UPM offers Form, Fit and Function replacement for any analog or digital panel meter.  If not, we'll make it!

The UPM-L can function as a Digital Panel Meter (D.P.M.), or as a universal counter. It measures and displays data from over 30 analog input signals. The Powerless™ input signals include A. C. V/A/W/Hz and CURRENT LOOP and it uses the patented Powerless™ new technology of our NTM Series bar-digital meters/controllers. It features input signal failure detect/alarm and isolated serial I/O, all powered by the signal it measures. Powered models can have relays/O.C.T. & analog outputs to control your process, as well as ethernet & µSD for data logging.

As a Counter-Timer-Clock-Frequency monitor, the UPM-L offers over 32 functions that are selectable via serial commands. The Input levels (TTL/CMOS/open collector/dry contact/high voltage) will vary depending on your specific configuration, but all models allow you to perform math functions using X-Y tables, polynomials, LOG & ANTI-LOG and more. Keep in mind that since we use floating point math, the possibilities are limitless.
