PCB Piezotronics has added two new models to its 482 Series of benchtop signal conditioners. The Model 482D27 and Model 482D64 are four-channel, line-powered units for general test and measurement work, and both bring modern digital control, lower noise and higher gain to a product family that is already a familiar sight in UK test laboratories.
Digital control over USB-C and Ethernet
The headline change is the control interface. Both models can now be set up over USB-C or Ethernet, which makes it quicker to configure gain, filtering and sensor type across all four channels, and easier to keep set-ups consistent between tests. For labs running several rigs, that means less time at the front panel and fewer manual set-up errors.
Two models for different sensor types
The 482D27 supports bridge/differential, ICP® and voltage sensors. It provides increased excitation current so it can drive selected Endevco triaxial low-resistance piezoresistive accelerometers, which are widely used in shock and crash testing.
The 482D64 supports charge, ICP® and voltage sensors and adds DC coupling. This is particularly useful with ICP® force and pressure sensors that have long discharge time constants, as it allows temporary measurements down to 0 Hz.
Key specifications
- USB-C and Ethernet digital control
- Improved noise performance on both models
- Gain of up to x1000 for ICP® and voltage sensors (482D27) and for ICP®, voltage and charge sensors (482D64)
- Upper frequency response to 225 kHz (-3 dB) on the 482D27 and 100 kHz (±5%) on the 482D64
- Optional input filters (before gain, to stop out-of-band content overloading the conditioner) or output filters (after gain, to remove unwanted noise)
Where it fits in a UK test set-up
A four-channel benchtop conditioner like the 482 Series sits between your sensors and your acquisition system. It pairs naturally with PCB’s general purpose accelerometers, high sensitivity accelerometers and high temperature accelerometers, feeding a dynamic signal analyser such as the Spider-80X high channel measurement system for frequency response and time waveform recording work. PCB positions the new models for automotive, aerospace and defence testing as well as general laboratory use.
