Acromag TT351 strain gauge or load cell transmitters

Acromag’s TT351 load cell or strain gauge signal conditioners use software to quickly select from a wide variety of sensor measurement options. A USB port simplifies set-up on a Windows PC or Android mobile device with Acromag’s Agility app. Software menus help users set the sensor type, bridge configuration, excitation source, filtering level and input/output ranges.

Advanced capabilities let users fine-tune scaling of I/O signals, adjust excitation levels and calibrate the bridge. Universal output supports six ranges including 4–20 mA, 0–10 V and ±10 V. Flexible power accepts a 9–32 VDC supply at the terminals and a rail power bus option can supply multiple units from a single connection or establish redundant power.

The narrow 17.5 mm housing mounts easily on a DIN rail. Hazardous location approvals, high noise immunity and a -40 to 70°C operating range make the transmitters suitable for use in harsh environments. The software-configured bridge sensor transmitters offer capabilities not possible with DIP switches or pot adjustments for a broad range of load cell, strain gauge, weight and force measurements.

The TT351 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 applied at the sensor and enable lead-wire compensation. The differential input is designed to perform true ratio-metric conversions for stable measurements that remain accurate over time and temperature. Lead break detection is inherent in the device, while three-way isolation between input, output and power should increase safety and noise immunity.
