The Mantracourt SGA is a robust analogue strain gauge amplifier or signal conditioner housed in a waterproof IP67 / NEMA 4 ABS enclosure, supporting AC (110/230 V) or DC (18 to 24 V) power. It drives up to 4 pcs 350 Ω load cells and delivers selectable outputs including ±10 VDC, ±5 VDC, 0-10 V, 0-5 VDC, 0-20 mA, and 4-20 mA.
The SGA analogue strain gauge amplifier bridges the gap between a raw load cell signal and the analogue inputs of PLCs, data acquisition systems, and process controllers. Available in AC-powered (SGA/A) and DC-powered (SGA/D) versions, it suits both panel installations and field-mounted enclosures.
The IP67 / NEMA 4 ABS field case with three M16 cable glands withstands wash-down, rain, and dusty industrial environments without additional protection. A wide range of selectable output options means the same unit integrates with virtually any analogue input card, and the bridge completion module (SGABCM) extends support to quarter- and half-bridge configurations for strain gauges in structural monitoring and test benches.
