Product Details

The High Resolution 24-Bit Bulkhead Mounted Strain Gauge Indicator SMW-HR has the same features as the Bulkhead Mounted Strain Gauge Indicator but with a very high resolution (24-bit) A-D converter of 500,000 counts.  It is optimised for single or multiple load cell and weighing applications.

The SMW-HR is ideal to use in multi-range scales and for applications where the live weight is very small in relation to the dead weight (tare weight).

The 24-Bit Bulkhead Mounted Strain Gauge Indicator has a 4 point linearisation capability and its 6-wire measurement system can compensate for zener barrier losses.

The digital architecture offers very easy one-pass calibration and fast setup. This versatile digital load cell amplifier offers options of isolated analogue outputs, latching relays or digital outputs for control or alarm functions.

The RS232 or RS485 options provide for digital communications (including setup) and can support label or ticket printers.
