PW15AHi load cells belong to the digital load cell and measuring chain family
specially developed by HBM for rapid dynamic weighing processes. They
acquire measurement signals from strain gages, condition them digitally, output
them and can network them for buses on request.
They supply a fully‐filtered, scaled and digitized output signal for direct
connection to a bus system or a PC. They operate at high data rates of up to
1200 measurements per second and can be easily and rapidly adapted to the
actual weighing system by means of adjustable parameters.
The integrated trigger function allows event‐driven determination of weight,
which greatly reduces the external software requirements for checkweigher
applications, for example.
The PW15AHi includes dosing control. As this load cell does not have any
digital outputs, the external Master control must make digital I/Os available.
The PW15AHi generates the information to control these digital outputs in the
respective measurement statuses (MSV measurement status). The Master
control then only needs to forward these control bits to its digital outputs to
drive the dosing control valves.
The load cell is supplied as required with an RS485, CANopen or DeviceNet
interface.
PW15AHi load cells are designed in stainless steel and have a high degree of
protection (IP 68).
The AED_Panel 32 PC software is available to facilitate parameter settings, to
display dynamic measurement signals and for comprehensive frequency
analysis of the dynamic system.
This part of the operating manual describes the hardware and the functions of
PW15AHi digital load cells. The commands for serial communication are
described in the online documentation (= AD103C commands).
