Overview• Linux®

All USB-TEMP and TC Series devices support thermocouple inputs. The USB-TEMPand USB-TEMP-AI also support RTD, thermistor, and semiconductor sensor measurements. In addition, voltage measurements are supported by the USB-TEMP-AI
and USB-TC-AI. Each device also includes eight digital I/O lines.

• Android™

Counter Input

The USB-TEMP and USB-TC Series offers the most accurate temperature measurement possible, since the internal measurement electronics accuracy exceeds theaccuracy specifications of the temperature sensors.

USB-TEMP-AI and USB-TC-AI devices havea 32-bit event counter that accept frequency inputs up to 1 MHz. The internalcounter increments when the TTL levels
transition from low to high.

The combination of the USB-TEMP and USB-TC Series and the Measurement
Computing DAQ software suite gives you a complete data acquisition solutionthat will have you taking measurements in minutes.

Analog Input

Sample RateThe 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 feature four thermocouple inputs plus four
voltage inputs with ranges up to ±10 V.
The USB-TEMP-AI also supports RTD,
thermistor, and semiconductor sensor measurements. The USB-TEMP-AI
and USB-TC-AI also offer four voltage 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) sensors are provided for TC measurements,
and built-in current excitation sources forresistive sensor measurements.

Measurement Computing

Calibration

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 withexternal 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 programmable for input or output.

USB-TEMP and USB-TC Series devices arefactory-calibrated using a NIST-traceablecalibration process. Specifications areguaranteed for one year.
The USB-TEMP and USB-TC Series also
supports field calibration for users to
calibrate the device locally with the InstaCal utility.
InstaCal prompts you to run its calibration
utility when you change from one sensor
category to another. Allow the device tooperate for at least 30 minutes before
calibrating. This warm up time minimizes
thermal drift and achieves the specified
rated accuracy of measurements.
