CHAPTER 1: INTRODUCTION
CHAPTER 1: INTRODUCTION
INTRODUCTION
The STXplus Signal Transmitter, shown
above, is a 4-channel signal processor that
receives an analog input from strain gage
sensors/transducers and provides 2-5A
ouput relays, current, and serial output. The
STXplus has a 23-bit analog-to-digital (A/D)
converter that provides high resolution.
PHYSICAL DESCRIPTION
The STXplus PCB can be configured in
several ways:
1. STXplus in Kister-Morse
®
Supplied Enclosure. The STXplus PCB is
housed in a NEMA-rated enclosure and
wall-mounted near the vessel. An
optional AC power supply can be
purchased, or customer-supplied DC
power can be used.
2. STXplus in a Customer-Supplied
Panel/Enclosure.
An optional AC
power supply can be purchased, or
customer-supplied DC power can
be used.
FUNCTIONAL DESCRIPTION
Analog Mode
The STXplus can receive an analog signal
from either half-bridge sensors/transducers
(Load Cell, Microcell, Load Stand II,
and Load Disc II) or from full-bridge
sensors/transducers.
The analog engine is calibrated using the
calibration buttons. When in Analog Mode,
current output from the STXplus PCB is
controlled by the analog engine.
Filters
The STXplus has several features which help
provide stable output. The Sentry™ DSP
Filter reduces output changes that can result
from vibration.
