Acromag TT351 strain gauge and load cell transmitter

Thursday, 28 April, 2022 | Supplied by: Metromatics Pty Ltd


Acromag’s TT351 model is a space-saving 4-wire transmitter that converts a 4- or 6-wire strain gauge bridge or load cell or millivolt sensor signal to an isolated voltage or current output signal. An optional DIN rail bus can deliver primary or redundant power to multiple units.

Set-up and calibration is via USB connection to a PC and Acromag’s Windows configuration software.

The transmitter’s input circuit allows true 6-wire bridge measurement and includes an adjustable bridge excitation supply (4–11 VDC) with a remote sense feature. Sense wires ensure the programmed excitation voltage is measured at the sensor and enable lead-wire compensation. The differential input performs true ratiometric conversions for stable measurements that remain accurate over time and temperature.

Advanced signal processing capabilities, variable range input and convenient USB programming make this instrument very versatile for strain/load measurement. One model can process strain gauge, load cell and millivolt input signals from 1–10 mV/V. Initial bridge offsets or forces can be automatically removed with null compensation, tare and zero-balance bridge functions. An internal half-bridge can perform half- and quarter-bridge completion with precision resistor pairs or bias a floating millivolt input signal. A custom input signal linearised function supports up to 25 user-defined signal breakpoints. Flexible scaling is independently adjustable for input and output.

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.
