🔍Product Overview
The ALTOM UT150-1 is a universal 2-wire temperature transmitter designed for industrial process control and monitoring applications.It converts signals from various temperature sensors—such as RTDs(Pt100,Pt1000,Ni100)and thermocouples(Type J,K,T,E,etc.)—into a standardized 4–20 mA analog output signal,which can be transmitted over long distances with minimal signal loss.
This loop-powered transmitter is widely used in industries including oil&gas,chemical processing,HVAC,water/wastewater,power generation,and manufacturing,where accurate and reliable temperature measurement is critical.
The UT150-1 features universal input compatibility,meaning it can be configured for multiple sensor types and temperature ranges,making it a flexible and cost-effective solution for diverse applications.
