| MODEL SSI |
 |
 |
| |
| |
|
The SSI is a TEDS IEEE 1451.4 compliant portable hand held smart sensor indicator. Just plug in a TEDS compatible Load Cell or Torque Sensor and the SSI will automatically self calibrate. When using a non-TEDS Load Cell or Torque Sensor the SSI can be setup by simple front panel push buttons. The SSI can be scaled to a full five digits from 0 to 99,999 to read directly in engineering units such as grams, ounces, pounds, inch pounds, etc. The SSI also has a units key for automatic conversion of readings for load, torque and pressure. The SSI has an ultra-fast signal-sampling rate of 15,360 samples/second for true peak, and or valley testing. The SSI also features an RS-232 port for data logging to a PC. You can also log data to the SSI’s internal memory. You can store up to 8,000 time and date stamped readings. The SSI also features 2 built-in, solid-state alarm relays, with LED and Audible indications. The SSI will operate up to 65 hours on a single charge or use the included battery charger for applications were the SSI is mounted permanently. |

| FEATURES |
 Approved- Plug & Play” operation with automatic scaling at power-up with TEDS IEEE 1451.4
compliant load cells.
- Menu-driven scaling of non-TEDS-compliant load cells via keypad with a choice of tw
scaling methods: manually entered coordinates of two points, or reading coordinates
of two points using input signals.
- PC-based scaling of non-TEDS-compliant load cells using Instrument Setup software,
again with a choice of two scaling methods.
- Keypad selectable units of measure for load, torque or pressure, with automatic conversion
of readings between units.
- Lockout feature to simplify meter operations and prevent inadvertent changes.
- Ultra-fast signal sampling rate of 15,360 samples/second (when set for 60 Hz noise
rejection) or 12,800 samples/second (when set for 50 Hz noise rejection).
- Normal conversion rate of 60/second (when set for 60 Hz noise rejection) or
50/second (when set for 50 Hz noise rejection), with digital averaging of every 256
samples. Allows display of filtered or unfiltered readings, capture of Peak, First Peak
or Valley.
- Selectable Fast conversion rates up to 7,680/second (when set for 60 Hz noise
rejection) or 6,400/second (when set for 50 Hz noise rejection). Always unfiltered,
allows capture of Peak or First Peak.
- Display update rate at 3.75/second (when set for 60 Hz noise rejection) or
3.125/second (when set for 50 Hz noise rejection). Display batch averages of 16
conversions or moving averages of conversions.
- RS-232 port for direct connection to a PC at baud rates from 300/second to
38.4k/second.
- Data logging to internal memory of up to 8,000 time and date stamped displayed
readings at up to 60 or 50 captures/second. Data logging may be single or continuous.
- Selectable memory protection to prevent overwriting previously stored data.
- Recall of internally stored readings to the meter display, a PC, or a printer with an
RS-232 interface. Recall may be single or continuous (standard capability).
- Recall of last meter calibration date.
- Data logging of time and date stamped values in real time via RS-232 (standard) to a
PC or printer. The values may be the current reading, Peak, Valley, or any combination
thereof.
- Optional PC Data Logging Software, P/N SSI-DLS. Collects real-time or stored data
via RS-232. Lists, plots or stores meter data in PC memory.
- Two built-in, solid state alarm relays, with LED and audible indications. Selectable
relay latching or non-latching, setpoint hysteresis or band deviation modes.
- Two control inputs assignable to Meter Reset, Peak & Valley Reset, Peak & Valley
Display, Tare, Tare Reset, and Log Trigger.
- Built-in load cell excitation voltage.
- Powered by a rechargeable 2400 mAh lithium-ion battery for up to 65 hours of operation.
Battery charge monitor circuit with bar graph and audible indications.
- Selectable automatic meter shutoff after interval of inactivity (15, 30 or 60 minutes).
- Wall plug type, UL-rated AC adapter / battery charger unit
