The BS-300A multifunction transducer Indicator/Controller is a highly versatile instrument suitable for use with any
strain gauge type transducer.
A feature of the instrument is its ability to be calibrated by simple front panel push button entry of any transducer's
sensitivity from the manufacturer's calibration certificate, followed by entry of the engineering units in which it is to be
used. Alternatively, conventional zero, span and analog output calibration is also available from the panel.
Other features of the BS-300A include push button tare, zero tracking, averaging, high/low relay outputs, peak hold
ａnd excitation for up to four 350 ohm transducers in parallel. Electrical connection is via the rear panel terminals,
including the facility for remote operation of the tare and peak hold functions. Options include 4-20mA, 0-10V DC,
RS-232C and BCD outputs. Housed in a rugged steel case, the BS-300A features a front panel measuring 88mm
x150mm, with an overall depth of 194mm. Suitable for panel or free standing use, the unit will operate on
110V,220V, or 240VAC.
Typical applications include weighing, batching, mixing, force, pressure, torque and displacement.
