Digital amplifiers from Synectic Design

Synectic Design is renowned for the high quality and excellent value instrumentation amplifiers produced, but now many process control systems require the digital input available from the latest units

Synectic Design is renowned for the high quality and excellent value instrumentation amplifiers they produce.

Synectic were one of the first manufacturers to build digital amplifiers and the depth of understanding and range that is offered reflects this.

As the company has been working in this field for many years we understand the market in great depth, this allows us to provide our customers with what they need now and in the future.

Synectic Design amplifiers can connect to various transducers including strain gauges and 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 digital amplifiers provide the digitisation and amplification function in one unit, whereas many competitive digital amplifiers require a digital junction box before the amplifier input.

Our digital amplifiers also work with digital load cells, accepting a digital input and simply amplifying it, retaining accuracy and avoiding any loss of clarity due to noise interference.

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 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 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.

Our 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 per 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.
