RTD to 4-20mA Converter | Save Cost in Industrial Automation. PLC Signal Conversion Trick. PT-100

In this video, I share a real-life industrial automation problem I faced with a faulty temperature sensor. The original sensor failed, and a new one would cost around 60,000 Taka. Instead of spending that much, I used an RTD sensor with a simple RTD-to-4-20 mA converter. The converter cost only 5,000 Taka, and the system started working perfectly. This video explains: ✅ Why an RTD sensor doesn’t directly work with a PLC that accepts only 4-20 mA signals ✅ How an RTD to mA converter solves the problem ✅ How I saved 55,000 Taka with a simple solution ✅ A practical lesson in cost-saving and smart engineering If you’re an engineer, technician, or student in automation, you’ll find this example very useful. #RTDto4mA #PLC #Automation #EngineeringSolution
