Digital amplifiers connect to various
transducers
Synectic design's amplifiers can connect to various transducers including: strain gauges, pressure transducers, but are most commonly used with load cells
Synectic Design says it is renowned for the high quality and excellent value instrumentation amplifiers it produces Synectic was one of the first manufacturers to build digital amplifiers and the depth of understanding and range that is offered reflects this, it adds

Digital amplifier is used as a local signal conditioning device for various strain gauge bridge configurations
Synectic design's amplifiers can connect to various transducers including: strain gauges, pressure transducers, but are most commonly used with load cells.
Most load cells produce an analogue output signal, but increasingly many process control systems require a digital input, therefore the load cell signal needs to be digitised as well as amplified.
This is where a digital amplifier is required.

Digitisation of load cell signals provides increased accuracy, resolution and reduced noise interference of the signal.
Synectic Design's digital amplifiers provide the digitisation and amplification function in one unit; many competitors' digital amplifiers require a digital junction box before the amplifier input says the company.
Synectic Design offers five digital amplifiers, tailored for different requirements.
The SY016 is a completely self contained unit which will provide excitation for up to four 350R bridges.
The device's built-in microcomputer calculates a temperature compensated 20 bit value (signed), which is directly proportional to the load.
The SY016 has typical reading speed of 200Hz (limited by Windows) and communicates via RS232.
The SY036 is a cased self contained unit which can be placed inline with a computer cable.
The unit has a 16 bit processor and can be connected through RS232, RS485, or now via USB.
A logger option is available and it is possible to scale the output signal to many engineering units rather than purely the raw signal.
Synectic's SY034 an SY044 are similar in terms of offering a high resolution 24 bit processor, operating at a speed of currently up to 100Hz.
The unit connects to a PC via either RS232 or the more popular USB option.
The difference between the two units is that the SY034 is a single channel amplifier and the SY044 is a dual channel amplifier, where both channels read simultaneously.
The final digital amplifier is the SY056 which is due to be released soon.
The SY056 will use a 24 bit processor that will read data at a speed of up to 2.5MSamples second.
The unit will connect to a PC via USB and transmit data at 400Hz when running in Windows or for ultimate performance over 500Hz when running on a Linux operating system.
