TWTADE / 0~150 Celsius RTD PT100 SBW Temperature Sensor Temperature Transmitter Isolated Detector Module 0~150 Degree - 4-20MA

Third time I purchased on of these. For some home and commercial applications. They work great and prices is great. (low)

Cumple funcionalidad pero contactos tienen problemas de ajuste

I got this as a demonstration tool to show how 4-20mA loop powered devices work. It's cheap and I haven't verified it's accuracy nor have I tested the high failure or reverse voltage protection, but it is only being used for instructional purposes. The build quality does not feel as though it would handle much of anything physical or damp environments.

Muy buen producto.

I haven't installed it yet as a backup boiler feedback. I did set it up on the bench and it seems to do what I need a 4-20 output transmitter.
