Buy Loadcell amplifiers and Strain Gauge Bridge amplifiers online

For most practical amplifiers, the input and output ranges are pre-defined and are optimised for a particular application. The user does not normally need to concern themselves with the gain calculation, but may need to select the ranges from a row of switches or links.

The dynamic range is the frequency range over which the output can track the input. For slow-changing measurements such as weighing of silos and tanks, using a narrow bandwidth will give benefits in terms of noise and stability. For fast changing (dynamic) measurements such as engine torsional vibrations, then a wide bandwidth (> 1 kHz) is usually required, and short-term stability is less important.

The characteristics of an amplifier are defined in the specifications section of the relevant data sheet and should be compared against the essential requirements of the measurement task. As a general rule, first select the appropriate input and output range, then consider the bandwidth and filtering options, before going on to details such as stability and temperature performance.
SY047 Dual Channel Digital Load cell Amplifier

SY047 Dual Channel Digital Amplifier
Suitable for two different inputs!

The SY047 compact, 24 bit dual channel digital amplifier is characterised by simultaneous conversion of 2 input channels, the conversion rate can be set with eight different conversion rate options available programmable from the PC. (max 500 readings per second, 300 readings per second in real time, limited by PC serial interface) RS232 and USB versions are available.

SY038 Strain Gauge Bridge Amplifier

SY038 Strain Gauge Bridge Amplifier
User Selectable Sensitivity!

The SY038 is a strain gauge bridge amplifier. It has the best stability in its class and high immunity to interference. In a very compact Din Rail mounting format  unit has the benefit of user settable sensitivity range. A miniature dip switch enables the user to select one of 16 ranges for transducer outputs as low as 0.25mV/V  up to 4m.4V/V (higher if specified) Non-interactive Zero and Span are screw driver adjustable giving a further +/-20% adjustment.
The amplifier can be ordered with a 2 pole low pass Bessel filter fitted, for applications where low noise is more important than bandwidth.
The DC powered unit is packaged in a very neat 72.5 x 18 x 62mm Din rail case, with connection made by rising clamp terminals with 3.5 x 2.5mm apertures.  The Mains powered version is housed in a wall mount IP65 sealed ABS Case measuring 162x83x55mm.   Both versions can drive up to 4 350ohm load cells.
