SY011 Loadcell Amplifier


Small size 4 to 20mA, ±5V or ±10V output 5 or 10Vdc stabilised loadcell supply Low zero drift 1kHz bandwidth (-3dB)
This loadcell amplifier is designed for use with strain gauge loadcells. It provides industry standard current or voltage outputs for accurate interfacing of loadcells with control and monitoring systems. This amplifier is ideally suited to engineering applications. Its small size makes it easy to mount inside existing equipment. The voltage output version of the amplifier has a bi-polar output for use with bi-directional loadcells even though it is powered from a uni-polar supply. The amplifier is easily calibrated using non-interactive zero and span trimmers. When it is purchased with a loadcell it will be calibrated for use with the loadcell. This amplifier can be used with any of our loadcells. Details of our loadcell families can be found in the Loadcell Specifier Guide.

**SY011 Order codes**
SY011	A	B	C	D
Replace A, B, C and D with the required codes from the list below.
A	Basic type
A	V for voltage output, I for current output.
B	Amplifier output
B	005 for ±5, 010 for ±10V, 420 for 4 to 20mA.
C	Loadcell excitation voltage
C	05 for 5V, 10 for 10V.
D	Loadcell output in mV/V
D	Usually 1.0 or 2.0, other values are possible.
Example: SY011I-420-10-2.0 This has a 4 to 20mA current output, 10V loadcell excitation and an input sensitivity of 2.0mV/V for full range.

If the SY011 does not have all the functions you require the LCA15 Intelligent Loadcell Amplifier may be more suitable. An LCA15 data-sheet is available in the on-line catalogue.

This instrumentation product complies with the requirements of the European EMC directive.
