nnnnSMW
nnnnIntelligent Loadmeter
nnnn♦ Auto calibration
nnnn♦ Tare, net and gross keys
nnnn♦ 4 to 20mA and 0 to 10V output as
nnnnstandard
nnnn♦ ABS case sealed to IP65
nnnn♦ Password protection of calibration
nnnnThis panel or wall mounting loadmeter is designed for use with strain gauge loadcells.
nnnnIt is a self contained instrument that combines ease of use with a wide range of features
nnnnincluding analogue output as standard and options to add trip points and serial
nnnncommunications.
nnnnThe 4 to 20mA and 0 to 10V outputs can both be used at the same time but only one can be
nnnnaccurately calibrated. See the SMW specification for more information. The normal set-up
nnnnis to calibrate the 4 to 20mA output accurately unless special instructions are given with an
nnnnorder. The analogue output is uni-polar so if a bi-directional loadcell is used the only way to
nnnnscale the amplifier is to set the mid-point of the analogue output equal to zero load. This
nnnnwill be 12mA or 5V.
nnnnAll set up functions are via the IP65 sealed keypad using a simple menu system. A version
nnnnis available for panel mounting in control enclosures, the main circuit board being DIN rail
nnnnmounted within the enclosure. The eight digit LCD display is also available with back
nnnnlighting.
nnnnAn RS232/RS485 serial communications option is available for single links or multi-drop
nnnnapplications of up to 25 weigh stations.
nnnnIf the SMW is supplied with a loadcell it will normally be calibrated to read the loadcell
nnnnoutput in the same force units as the loadcell calibration. A traceable system certificate will
nnnnbe supplied for the loadmeter and loadcell combination.
nnnnThis loadmeter can be used with any of our loadcells. Details of our loadcell families can be
nnnnfound in the Product List and the Loadcell Specifier Guide. If you require copies please
