TxBlock-USB Linearized Head Mounted Programmable Temperature Transmitter
Overview
The TxBlock-USB is a programmable Linearized 2-wire 4 to 20mA head mounted temperature transmitter. TxBlock-USB accepts Thermocouples J, K, T, E, N, R, S, B and Pt100 and Pt1000 RTD's. It can be optionally factory programmed or is quickly and easily programmed to your needs in the field using the optional USB Cable and Windows configuration software. The configuration is accomplished by connecting the transmitters USB micro-B port the of transmitter to your PC USB port. The configuration does not require that the transmitter be powered.Features
