One of the most compact load cell amplifiers available has been used as standard for strain, load and force measurement and can be supplied in two-wire or three-wire versions
The SY014 in-cell load cell amplifier from Synectic Design is a high quality amplifier for the load cell signal.
It is recognised for high quality performance, reliability and diversity, says the company.
Most importantly it is one of the most compact load cell amplifiers available.
The SY014 is available in two-wire or three-wire versions.
The two-wire version is loop powered from the amplifier circuit and the three-wire version is powered via an external power supply.
Output from the amplifier is via either voltage output (of 15-30V) or 4-20mA current output.
The 4-20mA output current is sourced form the output terminal, therefore the load cell should be between output and supply negative.
Operating voltage of the two-wire version is from as low as 5V up to 36V.
The three-wire version operates from approximately 10V to 30V; the input voltage is a selectable 11-20Vdc or 14-30Vdc.
The SY014 is designed for 200R or higher strain gauge bridges, working at a bandwidth of 3kHz.
The signal is can be adjusted by +/-20% using span trimmer and auto zero amplifier is possible with very high stability.
Unlike other competing units adjusting the zero trimmer to set the 4mA output does not affect the span as it is non-interactive.
The unit is also very stable as it has high noise immunity.
Response time for the SY014 at a scale of 500mv/V is 50 microseconds, with a typical rise and fall time is 75u seconds.
The SY014 has been used as standard for strain, load and force measurement, says Synectic Design.
While it has been designed specifically to measure the above, the company can modify it the measure whatever is required.
The SY014 in-cell load cell amplifier is a very compact unit, only 25mm in diameter, it is usually sold uncased, but casing is available if necessary.
Synectic Design has been designing and manufacturing industrial process control and measurement instrumentation and systems since 1993 and says it is considered a leader in the process electronics industry.
