Wireless Thermocouple System - Wireless temperature sensor:: TC-Link

Description

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

TC-Link® 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).

The TC-Link® can log data to internal memory or transmit realtime 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. TC-Link® 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® wireless thermocouple nodes, one USB base station, and PC software for wireless node configuration, data acquisition, and data display.
