Loop Power RTD Input Transmitter ST131

The Acromag ST131 is a loop power RTD Input Transmitter.

Firstly, it accepts 100 ohm Pt RTD or 0-900 ohm input. Producing 4 to 20 mA proportional DC output using 9-32V DC from the output loop power. It is also USB configured.

Secondly, setup and calibration are fast and easy. Simply by using the USB Connection to your PC and Acromag’s Windows configuration software. This temperature instrument is versatile with its advanced signal processing capabilities, variable range input and convenient USB programming. Therefore, making it ideal for RTD and resistance. Also designed to withstand harsh industrial environments and operate across a wide temperature range with low drift. It features RFI, EMI, ESD, EFT and surge protection plus low radiated emissions.

Other features of the Loop Power RTD Input Transmitter ST131 include:

• 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
• As well as a low temperature drift
• Fast response time (< 500µS)
