Force/weight transmitter
WST 3
Vishay Nobel Transducers
instruments designed for strain gage based transducer
applications. They convert load cell(s) input signals into highly
stable analog and digital output signals suitable for PC or PLC
based control systems.
WST 3 Transmitters typically are used where a local display
is essential either for weight/force indication or front panel
setup. Setup and calibration procedures are accomplished
easily using the front panel or by using PC based deltaCOM
software running under Windows 95/98/2000/ NT4/ME/XP.
All setup data can be stored in a host computer and quickly
downloaded into another WST 3 replacement unit (full
deltaCOM software option required).
Units are equipped with two relay outputs having a response
time of less than 20 msec. for use in high accuracy, level
control applications.
A unique and patented A/D converter, of high resolution and
stability, serves as the heart of the transmitter. This advanced
A/D drives both the analog and serial outputs which can be
user configured to transmit rapid, accurate, and stable
weight/force measurements.
WST 3 Transmitters offer on-board fieldbus communication
using the Profibus DP format. Fieldbus versions of Profibus
DP, DeviceNet, and Modbus Plus also are available through
the GATE 3S network module from Nobel.
WST 3 Transmitters are compatible with other Nobel
instruments and communicate via standard RS-485/
MODBUS RTU protocol with a common process control host
- PC/PLC.
The transmitter is CE marked, and fully compliant with EMC
and Low Voltage directives.
