MicroStrain 2.4 GHz TC-LINK Wireless Thermocouple Node

Introduction

Combining full thermocouple conditioning with MicroStrain award-winning wireless systems, is the TC-Link®-6CH complete wireless thermocouple node, designed for integration with wireless sensor networks.

This amazing new wireless sensor node features six standard thermocouple input connectors with an embedded cold junction temperature sensor. On-board linearization algorithms are software programmable to support a wide range of thermocouple types (J, K, R, S, T, E, B, N).

It can log data to internal memory and/or transmit real-time data to a base station transceiver at a pre-programmed rate, where data is displayed and logged for further analysis. Featuring programmable sweep rates, these little nodes pack a lot of power in a small package; and since each node has a unique address, a single host transceiver can address thousands of sensor nodes.

Embedded software provides wireless transmission at user-programmable rates from two samples per second to one sample every 17 minutes, and the processor conserves battery power by using micropower sleep modes in between samples. Enclosures include thin, rechargeable Lithium batteries.

The TC-Link®-6CH features an open-architecture bidirectional communications standard (IEEE 802.15.4 spread spectrum 2.4 GHz), which supports license-free operation worldwide. Starter kits include two TC-Link®-6CH wireless thermocouple nodes, one USB base station, and PC software for wireless node configuration, data acquisition, and data display.

Also included is a complete Data Communications Protocol manual to enable users to develop their own applications.
