TC-Link-200

Overview

The TC-Link-200 is a 12-channel wireless sensor for precise measurement of thermocouples and differential output sensors and requires no calibration; selecting the desired thermocouple type causes the node to output accurate, low noise temperature or mV data. It provides 12 input channels for thermocouples or differential voltage and includes onboard cold-junction compensation and onboard temperature calculation using NIST 9th order polynomial. Compatible thermocouple types are J, K, N, R, S, T, E, B. Digital filtering offers up to 120 dB rejection of 50 and 60 Hz noise and the node includes open-circuit (burnout) detection. Differential voltage range is +/-19.5 mV to +/-1.25 V and the device exhibits low drift over time and temperature. The node reports temperature or mV, supports up to 128 Hz sampling, and operates in continuous or event-triggered modes. The LXRS protocol allows lossless data collection, scalable network size, and node synchronization of ±150 µs, and onboard datalogging stores up to 8 million data points; wireless range is up to 1km and the product description lists long battery life. Power options are internal batteries (4 x AA Batteries) or external power (4.0 4.0 36 V. The TC-Link-200 is intended for precise measurement of thermocouples and differential output sensors and to report temperature or mV. Its wireless capability supports transmission up to 1km and onboard datalogging stores up to 8 million data points. The device supports sampling up to 128 Hz in continuous or event-triggered modes and can operate from internal batteries (4 x AA Batteries) or external power (4.0 4.0 36 V. Bolt down or DIN-rail mounting and an operating temperature range of -40 to +85 °C are provided for use within the specified environmental range.
