Technical Product Overview 2.4 GHz Wireless Thermocouple Node Introduction Features & Benefi ts
Combining full thermocouple conditioning with MicroStrain's
• 2.4 GHz direct sequence spread spectrum radio is license free
award-winning wireless systems, TC-Link® is a complete wireless
thermocouple node, designed for integration with wireless
• IEEE 802.15.4 open communication architecture
• 6 thermocouples per node provides low cost per channel
TC-Link® features six standard thermocouple input connectors
• supports simultaneous data transmission from multiple sensors
with an embedded cold junction temperature sensor. On-board linearization algorithms are software programmable to support
• internal memory stores up to 300,000 data points
a wide range of thermocouple types (J, K, R, S, T, E, B).
• sample rates from 2 samples per second to 1 sample every
The TC-Link® can log data to internal memory or transmit real-
time data to a base station transceiver at a pre-programmed
• communication range up to 70m line-of-sight, 100m with high
rate, where data is displayed and logged for further analysis.
Featuring programmable sweep rates, these little nodes pack
• supports type J, K, R, S, T, E, B thermocouples
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.
• includes on-board cold junction compensation
Embedded software provides wireless transmission at user-
programmable rates from two samples per second to one
• low-power consumption for extended use
sample every seventeen minutes, and the processor conserves battery power by using micropower sleep modes in between samples. Applications
Enclosures include thin, rechargeable Lithium batteries.
• civil structures sensing: concrete maturation
TC-Link® features an open-architecture bidirectional
• industrial sensing networks: machine thermal management
communications standard (IEEE 802.15.4 spread spectrum 2.4
• food and transportation systems: refrigeration, freezer
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 confi guration,
• advanced manufacturing: plastics processing, composite
• assembly line testing with smart packaging
