PR486A load cell amplifier

£360.00 exc VAT


The PR486A connects with a single set of 1 to 4 strain gauge load cells. It supplies 10V DC excitation and amplifies and conditions the resultant
return signal. From this signal and from stored control and calibration data it generates a gross weight signal for display and for transmission to PLCs and computers via its analogue output connection. Includes enclosure.
