The Acromag TT234 is a Potentiometer / Thermistor Input Transmitter.
Firstly, with a USB configuration, it isolates and converts Potentiometer / Slidewire Thermistor Inputs to a 4 to 20mA output. Power is received from the output loop current or a DC supply when using a three wire connection. The transmitter provides sensor excitation plus performs linearisation, lead wire compensation and lead break detection.
Secondly, Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software. A USB Isolator for calibration.
Thirdly, advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature measurement device. These transmitters can 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.
