The new SY035 compact weight indicator connects directly to the load cells and displays accurate ratiometric measurements on a five-digit LED display.
Digital amplifiers increase load cell accuracy
Synectic Design was one of the first manufacturers to build digital amplifiers, and the depth of understanding and range that is offered reflects this.
The single-channel version can display readings from load cells or similar transducers, the readings can be displayed in kilograms, Newtons, pounds, tonnes or user programmable units, such as kilonewtons etc.
The dual channel model can simply take readings independently as essentially two single versions, or the channels can work interactively.
The SY021 can operate interactively to produce for example load against displacement charts, where channel one reads a load cell and channel two reads, for example, an extensometer to provide the displacement or compression of the test piece.

Synectic Design can offer its customers solenoid valves at a competitive price and ensure the purchasing of such auxiliary items is as convenient as possible.
Matchbox-sized logger secures controller data
Data logging module is designed for use with highly successful batch control product range.
The two channels can also operate with a trigger function: this is handy if readings of (say) load only need to be taken once a test piece reaches a certain or critical temperature.
Once the critical temperature has been reached on the first channel, the second channel (load) starts to take readings.
Standard features on the SY021 include: a dual-line 16-digit LCD; a peak hold (62.5ms) (a faster option is available) or continuous measurement; a full numeric keypad; a battery life of 45h; and a zipped vinyl case.
The input and output working range of the unit is 0.5 to 4.5mV/V and a pulsed bridge excitation of 5V DC (to conserve battery life).
The SY021 has previously been used for tension testing carpets to testing soil samples outdoors.
The unit is also used to test the balance of the brake pistons on train brakes; the model used in this case is the dual channel version, where both force readings are displayed together on the dual screen so they can be compared.
The SY021 is being used as a portable field testing unit by civil engineers to measure the strength of soil samples; previously large laboratory testing equipment costing roughly GBP 5000 was used to carry out these tests.
The SY021 is much less expensive, yet equally (if not more) accurate.
Calibration of the load meter can be carried out by simply applying a known load or by entering a particular load cell's calibration data, essentially its mV/V scale and full-scale range.
The unit can hold in nonvolatile memory the settings for 100 different load cells etc (100 on the single-channel version or 50 per channel on the dual-channel version).
Options available with the SY021 include data logging - up to 3Kbyte - and ticket printing on demand for a batch of results.
The information printed includes: a programmable 50-character title, a batch reference and the peak values measured for each channel.
A rugged version of the SY021 is available if the unit is to be used in a particularly dirty environment, this version is also available with larger than standard rechargeable batteries.
