Wireless Thermocouple Measurement Module
Measurement Computing Wireless and USB 8 Channel Thermocouple Module
 The Measurement Computing WLS-TC is a USB 2.0 Wireless thermocouple input module. To use the WLS-TC in the wireless mode, it requires a WLS-IFC (USB-to-wireless interface module).
The WLS-TC can accept 8 thermocouple inputs in any combination of J, K, R, S, T, N, E, and B type sensors and provides two integrated cold junction compensation (CJC) sensors.
The WLS-TC features 8 independent temperature alarms. The alarms and all configurable options are software programmable. The WLS-TC is also fully software calibrated.
Each Thermocouple Module Includes:
>> AC-to-USB power adapter (2.5 watt supply for wireless operations)
>> 2 meter long USB cable
>> Measurement Computing’s DAQ software suite that includes, TracerDAQ, The Universal Library, Comprehensive drivers for DASYLab and NI LabVIEW as well as InstaCal software utility for installation, calibration, and testing.
NOTE: 1 Wireless Interface Device (#WLS-IFC) can be used for multiple Wireless Modules. Several Modules can communicate with only a single wireless interface.
Note: Any order for Measurement Computing Products to be Shipped Outside the US will require an "End User Export Agreement" form to be Completed and Returned Prior to Products being Shipped.
