Wireless Sensors Extend Their Talents

 LORD Sensing, MicroStrain launches three devices: two wireless temperature nodes that allow users to remotely collect data from a range of temperature sensor types and one wireless strain node that features three channels and a rugged, weatherproof enclosure.

The TC-Link-200 and RTD-Link-200 wireless temperature nodes offer the convenience of wireless sensing while maintaining high quality and reliable temperature measurements in demanding applications. Users can remotely collect data from a range of temperature sensor types including thermocouples, resistance thermometers and thermistors. Like all 200 series wireless sensing nodes, the latest offerings allow for on-board data logging as well as high speed wireless data transmission, allowing users to safely store data while at the same time transmitting the data to a central location for monitoring, aggregation and alerting.

Designed for use with common temperature probes, the nodes include cold junction compensation and linearization for thermocouples, and linearization of a multitude of resistance type temperature measurements. User configurable filter settings provide clean measurements even in EMI rich, noisy environments. The nodes feature low-power battery optimized operation for extended measurement life and are well suited for remote location applications and long-term condition monitoring. 

The SG-Link-200 Wireless Strain Node has three Wheatstone bridge type inputs optimized for use with strain gauges. The SG-Link-200 features a weather hardened IP68 rated ruggedized enclosure with integrated long-life user replaceable battery. It operates across a wide range of ambient temperatures (-40 to 85°C) and is proven to withstand submersion for greater than 30 minutes at depths of up to three meters. The strain node is compatible with many sensor types including strain gauges, load cells, pressure transducers and many more low voltage type transducers. SG-Link-200 is configurable for many applications, including outdoor structural health monitoring, off highway construction equipment and vehicle field test and measurement. 

SG-Link-200 features:

  • 24-bit native signal converter
  • Extremely low noise, as low as 1.0 µVp-p
  • User adjustable Low-Pass Digital Filter for noise reduction
  • On-board high precision temperature sensor (+/- 0.25°C)
  • Up to 1024 samples per second (2 channels)
  • Up to 512 samples per second (3 channels)

SG-Link-200 multiple operating modes:

  • Continuous, Periodic Burst, and Event-driven data collection options
  • Collect and transmit raw “waveform data”
  • Transmit mathematically derived outputs: RMS, Mean, and, Peak-peak 
  • Data-log to internal memory, 16MB (Up to 8 Million data points)
