The PR430 Weight Indicator connects with up to four strain gauge load cells. It supplies 10V DC excitation and amplifies and conditions the resultant return signal. From this signal and stored configuration and calibration data it generates a gross/net weight signal for display and transmission to PLCs and computers via its analogue, serial or network communications interface.
Powerful ‘System On Chip’ technology provides outstanding levels of accuracy and stability combined with drift compensation.
Calibration adjustments are performed by means of the keypad in conjunction with the LED display. Access to calibration data is pass-number protected.
The weigher may be calibrated using a single test weight; often of considerably lower weight than the weigher capacity.
In addition to the conventional method of applying test weights, calibration can be achieved by entry of the precise sensitivity and capacity figures from the load cells.
Each PR430 is factory calibrated to have the same precise input range. This facilitates unit replacement, without the need for vessel emptying or recalibration, by entry of zero and gain coefficients.
Dual trip relay outputs are provided with independent level, deadband and high/low sense settings.
Select the perfect interface option to suit your application from the wide range available: Analogue, Serial, Profibus DP, DeviceNet and Ethernet Modbus/TCP.
The fourteen segment super-bright Light Emitting Diode (LED) display characters offer the advantage of a high visibility display, regardless of ambient light conditions, along with easily recognisable alpha-numeric characters to make operation and configuration simple and effective.
