1 New! WORLD S SMALLEST BARGRAPH METER LOOP OR AC/DC POWERED > 3 INPUT SIGNAL CONDITIONERS Model SBM FEATURES: *3 Colors: red, green or yel. * Dual Independent A/D (For Bar & Digital) *Loop Powered (4-2mA) *3-1mA Signal Powered *4-3VDC Signal Powered *5-32VDC or VAC *Plastic or metal case (seismic tested) *Mil-Spec, Nuclear or Industrial grades *Lifetime Warranty (Ltd). DESCRIPTION: OTEK s new SBM joins the world s largest selection of loop power meters from a single manufacturer with 3 patents on loop power instruments and the widest selection of bargraphs approved for nuclear, mil-spec and hazardous applications. THE DISPLAY: The new SBM uses the latest LED technology for high reliability and low power consumption; hence, long life expectancy (>3 years). If You Don t See It, Ask For It! Tel: Fax: Toll Free: 877-BAR-OTEK ( ) sales@otekcorp.com Web: The SBM combines 2 technologies, the analog bargraph to give you the process trend, with 2% resolution and its own A/D with zero and span controls. The digital A/D gives you high accuracy and resolution of.5% in engineering units, also with its own independent zero and span adjustments. See ordering information for colors and vertical or horizontal options. Since 1974 Deg.C: (Basic VDC Input) Bargraph: (51 Segments) *Accuracy: +/-.5% +/- 1 Bar *Resolution: 2% of Full Scale *Bar Length: 1.7 (42 mm) *Bar Width:.16 (4mm) Digital: *4 Digits ( ) *Accuracy: +/-.5% of F.S. +/- 1 Digit *Resolution: +/-.1% of Full Scale *Digit Height:.22 (5.6mm) *Power Consumption: <.1 Watt *Op/Storage Temp: -2-6/- 3-7C *CMTBF: >1, Hours THE SIGNAL CONDITION- ERS: The SBM offers over 3 signal conditioners and OTEK s motto is If we don t have it, we ll make it. Now you can watch your process trend with the bargraph and its accuracy with the digital. All in the smallest and most cost effective package. The dual A/D of the SBM allows you to independently scale & zero the bargraph from the digital with +/- 3% range of zero and full scale. For wider range, specify under digit #8 on ordering information (Option #9). 416 E. TENNESSEE ST. TUCSON, AZ U.S.A. MADE IN USA

2 HOW IT WORKS: INPUT TYPE (DIGIT 2) OPTION, LOOP POWERED: Only 2 wires (+L & -L) required. The SBM requires >3mA to operate at ~4 V drop, if the 4V drop is too much, select Option 1 (Externally Powered) Also, display intensity is lowest at 4mA and brightest at 2mA. OPTION 1: 4-2mA EXTERNAL- LY POWERED: It only 2mA (5 Ohms) but the "SBM" needs 5mA to operate. Accuracy: +.5% of F.S. OPTIONS 2-7: VDC & madc EXTERNALLY POWERED: Input impedance is 1 Mega Ohms on all VDC ranges and 5 Ohms on 1 ma range. Accuracy: +.5% of F.S. OPTION 9: CUSTOM: Use this option to describe any custom input, scale or modification to the SBM and contact us for feasibility and cost. Option A: 4-3VDC Signal Powered: Another OTEK innovation. The voltage signal powers an LDO to protect the SBM and a divider network is used to measure and display the signal. If the relatively low impedance (5 Ohms) and current (3-2mA) required by this Powerless TM technique is unacceptable, use Options 2-8 (externally powered). Option C & D: These are higher sensitivity (1uV) versions of Option 5. Zin is 1 MEG Ohm. Same Connections. Options E-M: V & ma RMs: Here we use a True RMS-DC Converter for accurate (+.5%) measurement of sine waves up to 1KHz (+.5%, 1-2KHz) and SCR;s fired to + 2%. Input impedances vs. range are the same as for VDC ranges. Option N: 5Amps AC: Specifically for current transformers (C.T.) this option requires an externally mounted (supplied).5 Ohm,.1% 3 Watt resistor. You can mount the "Shunt" at your C.T. or next to the SBM but make sure the connections are "Perfect" to electrical codes. The C.T. might have "Lethal" High Voltage without a "Shunt" (Open) and the SBM will "Smoke". See OTEK's New ACS models for C.T. powered instruments (Patent #7,626,378). Option P: Strain-Gage (<1K Ohm Type): Here we use a high accuracy and stability constant current (~1mA) source, and a differential amplifier to convert the 2 or 3m V/V (typical) sensitivity of your "Loadcell." Specify your Strain-Gage sensitivity and full scale and the SBM's display at Zero and Full Scale Please! Accuracy: ±.5% of F.S. Option Q: Strain-Gage (>1K < 5K Ohm): These are typically "Monolithic" S-G that require constant voltage (preferably) excitation. We use 4.96 V for high stability and accuracy. Specify your S-G impedance and sensitivity and the SBM's display at Zero and Full Scale. Option R: RTD (PT1): We excite your 2, 3 or 4 wire RTD with 2uA to avoid the "self heating" effect. The range of the SBM is the same as your RTD typically -2 C to +8 C ( F). You can place the decimal point at will (typically -2. to 8. (-328. to 1562.)). The PT1 has a temperature coefficient of.385 Ohms/Ohm/ C. For 1 Ohm RTD(PT1) & legacy.392 TC (known as ANSI 392) contact OTEK and use Option "9". Option S: Thermocouple (Type J): This TC has a range of -21 to + 76 C ( F). Its color is white (+) and Red (-), cold junction (CJ) is inside the SBM at the connector base. Make sure the connections from your TC are as close as possible to avoid errors and calibrate after connecting. If you short out the SBM's TC wires together, the SBM will read the ambient temperature due to its built-in C.J.C. Contact OTEK for types "K," "T" and others, including copper (1 Ohms). Options T: Frequency Input: We use an F-V to accept frequencies from 4-2KHz and amplitudes from 1-4V peak or dry contact or open collector transistor (O.C.T.). For 5-44 Hz power line frequency measurement use Option #"8" or see our ACS Powerless TM Series. Option U: %RH: This conditioner is designed to interface to a typical (capacitance type) 2-3pF/% of RH made by several manufacturers. Use Option "9" and contact OTEK to specify your sensor's specifications. Option V: ph (Acidity): We use a FET input (115) amplifier and calibrate the SBM for -14. ph using the Industry s standard mv = + 7pH co-efficient. Accuracy: +.5% of F.S 2

3 Option W: ORP(Oxygen Reduction Potential): Our FET amplifier (1 9 ) accepts the industry standard 2mVF.S. of the probe and the SBM displays it in % (-1.%) Option X: Hi Speed Peak & Hold (P&H ): Now you can capture fast transients greater than 5 microseconds (even faster soon) with resolution greater than.1% of F.S. and retention of greater than 1 years (Due to OTEK's new and patent-pending P&H Option). Input: V or madc (Specify Range). Contact OTEK for V/ ma RMS or Loop Powered). Accuracy: +/-.1% of F.S. +/- 1 Digit Linearity & Resolution: +/- of F.S. Response time: >2KHz (<5us) Retention: >1 years (with power on). More: New Signal Conditioners will be added as per your requests and popularity, such as Ohms, Conductivity, Shock, Vibration, Position etc. Contact OTEK. POWER/INPUT (Digit 3): OPTIONS -3: NON-ISOLATED POWER: All listed I/O options (except Powerless ) are available. Power requirements vary with options included. The basic SBM requires under 15mW (3 ma@5vdc). Fully Loaded: 1 watt. OPTIONS 4-8: ISOLATED POWER These options offer minimum isolation of 5 VAC or DC and their efficiency is about 8%. All power input ranges are +/-1%. 3
