Lord Sensing SG-Link-200 wireless sensor

The SG-Link-200 is a 3-channel wireless sensor with a rugged, weatherproof enclosure. It includes onboard PGA, filtering and a high-resolution ADC for precise measurement of a large range of sensor types, including strain gauges, load cells, pressure transducers and accelerometers.

The product has three differential input channels, adjustable gain (1 to 128), adjustable filtering, high-resolution 24-bit data and noise as low as 1 µV p-p.

Compatible with 120, 350 and 1 kΩ Wheatstone bridge sensing circuits, the sensor includes a temperature sensor and either a 1.5 or 2.5 V sensor power output. It also features remote strain calibration using an onboard shunt resistor, as well as available factory bridge completion (¼, ½ or full-bridge).

The battery-powered wireless sensor has continuous, periodic or event-triggered operation; a continuous sampling rate of up to 1 kHz; wireless range of up to 1 km; and data logging for up to 8 million data points.

The LXRS protocol allows lossless data collection, scalable network size, node synchronisation of ±50 µs, and output waveform data and/or derived parameters (mean, RMS, peak-peak). The duty-cycle sensor excitation for low-power operation is well suited to battery-powered applications.

The SG-LINK-200 package includes: weatherproof IP68; mount with 2 x M8 screws or 3M VHB 4941; stainless steel compression limiters; and an operating temperature range of -40 to +85°C. It is powered with a D-cell battery or input 4–36 VDC.
