Single-Channel Thermocouple Measurement Device

Thermocouple Input

The USB-2001-TC is a USB device that

takes measurements from type J, K, R, S,

T, N, E, and B thermocouples.

The thermocouple type is software pro-

grammable and stored on the device. A

20-bit ADC processes the data conver-

sions.

Thermocouple input ranges are

±73.125 mV (calibrated) and ±146.25 mV,

(not calibrated). The ±146.25 mV range

is used for open thermocouple detection.

The device has an integrated cold junction

compensation sensor.

Open-Thermocouple

Detection

The USB-2001-TC is equipped with open-

thermocouple detection.

With OTD, any open-circuit condition

at the thermocouple sensor is detected

by the software. An open channel is

detected by driving the input voltage

to a positive value outside the range of

the thermocouple output. The software

recognizes this as an invalid reading and

returns the value “OTD”.

The USB-2001-TC provides reliable temperature measurement at an affordable price

Overview

The USB-2001-TC is a single-channel, 20-bit, thermocouple input DAQ device

that measures temperatures in the ranges defined by NIST J, K, R, S, T, N, E, and

B thermocouple types. It features a 4 S/s sample rate, integrated cold junction

compensation, and open thermocouple detection.

The USB-2001-TC has a small form-factor, and is designed with a captive USB cable

attached to one end, and a socket on the other end for receiving industry-standard

thermocouple miniature connectors. The USB-2001-TC gets power from the host

PC via the USB cable, and requires no external supply.

The USB-2001-TC provides an ideal solution for embedded applications that require

reliable temperature measurements at an affordable price point.

Thermocouple Connectors

Users can quickly connect a thermocouple

to the USB-2001-TC with a standard min-

iature connector.

Thermocouple miniconnectors are avail-

able for purchase from Measurement
