The accuracy and resolution of a signal generator are crucial as they determine how precise and stable its output is. Look for a device with high accuracy (usually expressed as a percentage) and resolution (expressed in decimal places).
Digital Display
Having a digital display on your signal generator can make monitoring and adjusting its output much more manageable. It allows you to see the exact value of the output current, reducing any chances of errors.
Multiple Output Options
Some advanced models of 4-20Ma signal generators offer multiple output options such as voltage or frequency outputs in addition to current output. If your application requires these additional outputs, consider investing in such models.
Budget Considerations
The price range for a good quality 4-20Ma signal generator can vary greatly depending on its features and brand. While it may be tempting to go for cheaper options, keep in mind that quality and accuracy should not be compromised when it comes to industrial equipment. It is advisable to invest in well-known brands with good reviews from other users.
Maintenance and Support
Like any other electronic device, regular maintenance may be required for your signal generator’s optimal performance. Before purchasing one, make sure to inquire about its maintenance requirements and if there are any additional costs involved. Additionally, check if there are warranties or customer support available from the manufacturer.
