The HI-QSLIM series is a part of Otek’s low cost smart indicators that are versatile and programmable. This series has a variety of display options including a bar graph display with a 51-segment LED array or a 101-segment LED array and a standard 2-digit LED display, available in horizontal or vertical configuration, and a simple 8-digit remote display with limited alpha charachters. Standard colors include red or green with other colors available upon request. As with many of Otek’s products, this meter series has the ability to display a number of variables and scales using 4-20 mA or VDC inputs, including watts, volts, amps, RPM, percent, or any other sensor output. The HI-QSLIM models feature a serial input allowing for use as a serial remote display, or a slave display, for plant intranet. With inputs including RS232C, RS485 I/O or USB I/O, for PLC, DCS and SCADA, making these digital panel meters ideal for any process monitoring needs.

Otek specializes in customizing instrumentation for process control and automation to fit a variety of needs. For more information please contact us. All of Otek’s products are covered by a lifetime warranty.




OTEK's LPT is discontinued.



OTEK's LSB (4.35"W x 4.35"H) is a loop powered switchboard/circular bargaph with a 4 1/2 digital LCD display. Great choice to replace old analog style meters. 

In 1975 OTEK introduced the World's First Loop Powered DPM. In 1979, The First Loop Powered Bargraph. In 1996 the Automatic Tri-Color Bargraph and in 2004 the World's First Loop Powered Serial I/O DPM. Now OTEK brings you the World's First Loop or A.C. Signal Powered Bargraph (Pat. # 7,626,378 & 4,908,569).  The bargraph gives you trend and digital accuracy.

The LSB is available with 101 segments. Loop Powered or externally powered, with or without automatic tricolor backlight. The LSB is fully configurable for many functions.
Standard calibration and configuration (unless otherwise specified) is:
a. Left Zero, 4-20mA or 0-2V = 0 - 100.0 & 0-100 bargraph segments.
b. Alarm Annunciators (bars only reverse acting) set for: 25, 50, 75 & 100% of Scale.
c. Backlight: Red: 0-10%, Amber: 10-20%, Green: 20-80%, Amber: 80-90%, Red: 90-100%. But, if  you need to change it, just plug a hand held terminal into the Com connector on the back of the unit.
LOOP POWERED:  Use it to monitor or control any process and if you enable the backlite colors, it will inform the operator of limits exceeded.  If you use the serial port it will communicate with other intelligent instruments (DCS, SCADA, PC, PLC, etc.) or even become a remote display. 
A.C. SIGNAL POWERED:  No power supply is required!  The LSB draws its parasitic power (~50mA) from the signal it measures.  Again backlite colors and RS232E are available to help you control the process.  WARNING:  No isolation; use P.T. and C. T. (no control outputs).
EXTERNALLY POWERED: Here you have access to ALL the LSB's features such as relays, analog out, USB, RS232C, RS485, math functions, X-Y tables, polynomials, floating point and more.
GRADES:   Nuclear:  For Class 1E;  Mil:  To specific Mil-Stds; Industrial:  Per these specifucations.
