The latest release in Acromag’s new ST130 series of low-cost, temperature transmitters is the Model ST133, an isolated thermocouple/millivolt signal conditioner. This high-performance version of the economy-level ST132 also converts sensor input signals from eight thermocouple types or a ±100mV range and outputs a proportional 4-20mA process control signal. However, 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 free 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. Pricing for these low-maintenance, high accuracy instruments starts at just $109.
