100 ohm Pt RTD or 0-900 ohm input
4 to 20mA DC output
9-32V DC from output loop power
USB-configured
The ST131 is a low-cost two-wire transmitter that converts a 100 ohm Platinum RTD sensor input to a proportional 4-20mA signal. Power is received from the output loop current. The transmitter provides sensor excitation and includes linearization, lead-wire compensation, and lead-break detection functions. Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software.
Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature transmitter for RTD and resistance elements. These transmitters are designed to withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.
Easy setup and digital calibration via USB with Windows configuration software
Flexible RTD or linear resistance input ranges
High accuracy and linearity
Advanced analog signal conditioning ASIC eliminates digitization errors
