Ultra-Fast Plug & Play Smart Portable Hand-Held Load Cell Indicator

Made in the USA

MODEL SSI

The SSI is a ultra-fast 15,360 samples/second Plug & Play Smart TEDS IEEE 1451.4 compliant portable hand-held Load Cell Indicator. Just plug in a TEDS compatible Load Cell or Torque Sensor and the SSI will automatically self-calibrate. When used with a non-TEDS Load Cell or Torque Sensor, the SSI can be set up by simple front panel push buttons. The SSI can be scaled to a full 5 digit display from -99,999 to +99,999 counts 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 capability. Auto-tare allows the meter to be set to zero for any input signal level. The SSI also features a USB port for data logging to a PC. You can also log data to the SSI’s internal memory storing up to 16,000 time and date stamped readings. The SSI also features 2 built-in solid-state alarm relays with LED and audible indicators. The SSI will operate up to 65 hours on a single charge or use the included battery charger for applications where the SSI is mounted permanently. Read additional article...

  • Selectable memory protection to prevent overwriting previously stored data.
  • Recall of internally stored readings to the meter display, a PC, or a printer with a USB 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 USB 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 USB. 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.
