USB-TEMP and USB-TC Series

Analog Input

The USB-TEMP and USB-TC each

include eight thermocouple inputs. The

USB-TEMP also supports RTD, thermistor,

and semiconductor sensor measurements.

The USB-TEMP-AI and USB-TC-AI fea-

ture four thermocouple inputs plus four

voltage inputs with ranges up to ±10 V.

The USB-TEMP-AI also supports RTD,

thermistor, and semiconductor sen-

sor measurements. The USB-TEMP-AI

and USB-TC-AI also offer four volt-

age input channels with ranges from

±1.25 V to ±10 V.

A 24-bit analog-to-digital (A/D) converter

is provided for each pair of analog inputs.

Users can connect a different category of

sensor to each temperature channel pair.

Open thermocouple detection (OTD) is

provided to detect broken thermocouples.

Cold junction compensation (CJC) sen-

sors are provided for TC measurements,

and built-in current excitation sources for

resistive sensor measurements.

Sample Rate

Each channel can be sampled at up to

two samples per second for a total device

throughput of 16 samples per second.

Digital I/O

Eight independent, TTL-compatible

digital I/O channels are used to monitor

TTL-level inputs and communicate with

external devices. The DIO lines on the

USB-TEMP-AI and USB-TC-AI can also be

used to generate alarms.

The digital I/O lines are software program-

mable for input or output.

The USB-TEMP Series provides temperature measurement flexibility as each channel can

monitor any of the supported input types

Temperature Measurement Devices

Counter Input

USB-TEMP-AIandUSB-TC-AIdeviceshave

a 32-bit event counter that accept fre-

quency inputs up to 1 MHz. The internal

counter increments when the TTL levels

transition from low to high.

Calibration

USB-TEMP and USB-TC Series devices are

factory-calibrated using a NIST-traceable

calibration process. Specifications are

guaranteed for one year.

The USB-TEMP and USB-TC Series also

supports field calibration for users to

calibrate the device locally with the Insta-

Cal utility.

InstaCal prompts you to run its calibration

utility when you change from one sensor

category to another. Allow the device to

operate for at least 30 minutes before

calibrating. This warm up time minimizes

thermal drift and achieves the specified

rated accuracy of measurements.

Overview

All USB-TEMP and TC Series devices support thermocouple inputs. The USB-TEMP

and USB-TEMP-AI also support RTD, thermistor, and semiconductor sensor mea-

surements. In addition, voltage measurements are supported by the USB-TEMP-AI

and USB-TC-AI. Each device also includes eight digital I/O lines.

The USB-TEMP and USB-TC Series offers the most accurate temperature measure-

ment possible, since the internal measurement electronics accuracy exceeds the

accuracy specifications of the temperature sensors.

The combination of the USB-TEMP and USB-TC Series and the Measurement

Computing DAQ software suite gives you a complete data acquisition solution

that will have you taking measurements in minutes.
