WF 3144 Programmable Resistor

WF 3144 Programmable Resistor

Can I use the WF 3144 to simulate a PT-100 sensor?
Answer: Yes, the WF 3144 is well suited for simulating PT-100 sensors. Many of our customers use the WF 3144 for PT-100 simulations in for example HIL (...

What is the resolution of the WF 3144?
Answer: The resolution of the WF 3144 varies over the range and can't be expressed in bits or ohms. Instead the resolution is expressed as a error that...

Can I use the WF3144 to simulate a PT-1000 sensor?
The module could easily simulate PT1000 sensors, the only difference is that the error is slightly higher than for PT100. For the range you specified, -15...

Can I set a higher resistance than 160kOhms for a channel
Yes you can! The highest possible resistance that can be set is 768kOhms. The error will however be >10%.
