The TxBlock-USB is a low cost, high-accuracy USB programmable loop-powered head mounted temperature transmitter. The TxBlock-USB accepts most common temperature sensors including thermocouples, RTDs, thermistors and 0-50 mV signals. It provides a linearized 4-20 mA output and configurable measurement range.
USB Programmable
The TxBlock-USB is fully programmable through a USB connection. Free software is available via download for Windows computers or Android devices. With the software you can set the following parameters:
Sensor Type
Input and Output Range
Output Behavior if Sensor Fails
Zero Offset Correction
The TxBlock-USB can be connected to a computer using a standard USB cable with Micro B connector. To connect to an Android device an additional OTG style cable is also required.
Robust Noise Immunity
The TxBlock-USB is compliant with the leading standards of electromagnetic compatibility and is highly immune to electrical noise, making it well suited for industrial environments. The TxBlock-USB is supplied with an accredited calibration certificate according to ILAC (International Laboratory Accreditation Cooperation)
