New Head-Mount Thermocouple Transmitter Provides High-Voltage Isolation to Prevent Damage and Errors

Acromag's ST133 isolated thermocouple/millivolt signal conditioner is a high-performance version of the economy-level ST132. It also converts sensor input signals from eight thermocouple types or a ±100mV range and outputs a proportional 4-20mA process control signal. The addition of 1500V isolation between the input and output circuit shields equipment from high-voltage surges and transient signals. The isolation also breaks up ground loops and reduces signal noise that could interfere with measurement accuracy. Installing this output loop-powered two-wire transmitter is easy and a USB connection to your PC simplifies set up using Windows configuration software. Units support mounting in DIN Form B sensor heads or on a DIN rail. They are CE compliant with pending UL/cUL Class 1 Div 2 Zone 2 approvals and operate reliably over a -40 to 80°C operating range.
