ME145: High-Precision Calibrator for Strain Gauge Amplifiers

The ME145 is a portable calibrator designed to simulate defined output signals from strain gauge sensors (force, torque, pressure, etc.). It enables verification and calibration of measurement amplifiers in the lab or in the field, with 0.05% accuracy and minimal thermal influence (< 20 ppm/10 K). Its rugged aluminum housing (145 × 95 × 74 mm, 470 g) and versatile connectivity options (screw terminals, 4 mm or M12 5-pin) make it a reliable tool for demanding industrial environments.

This calibrator stands out with three key advantages: 10 pre-set calibration steps (ranging from ±0.2 to ±3.5 mV/V), fine "Vernier" adjustment (±0.5 mV/V in continuous increments), and simulation of 1/4 or full bridges (350 Ω or 88 Ω). Polarity switching (+/–) and compatibility with 3-wire technology simplify testing on amplifiers or measurement systems.

This solution is ideal for calibration laboratories, factory maintenance departments, or integrators of weighing and quality control systems. It meets the needs of the aerospace, automotive, energy, and medical sectors, where measurement traceability is critical—such as for calibrating force sensors on test benches or validating measurement chains before commissioning.

The ME145 is available with optional accessories: 3 m M12 cable (SAC-5P), 5-pin Binder connector (713 series), or factory or DAkkS calibration certificates for enhanced metrological compliance. Its compact design and standardised connectors make it a ready-to-use tool, with no need for complex configuration.
