TT351: Strain Gauge Load Cell Signal Conditioner

TT351: Strain Gauge Load Cell Signal Conditioner Description

The TT351 load cell strain gauge signal conditioner is a space-saving four-wire transmitter. This model converts a four or six 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.

Setup and calibration are fast and easy with a convenient USB connection to your 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 to 11V DC) 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 ratio metric conversions for extremely stable measurements that remain accurate over time and temperature.

Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile strain gauge load cell 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.

IMPORTANT: To prevent damage or errors from grounded PCs and surges, Acromag strongly recommends use of their USB-ISOLATOR when configuring a TT350 Series transmitter.

Approvals: CE compliant. UL/cUL listed Class I Division 2 Groups ABCD. ATEX, IECEx certified Zone 2.
