TxIsoPack-USB is a fully isolated 4 to 20 mA two-wire loop powered temperature transmitter for in-head assembly. Complete sensor type selection and range configuration is achieved by connecting the device directly to a PC USB port thus not requiring any other interface, special converter or any additional driver. The isolated and linearized current output represents the sensor input signal according to the temperature sensor selected.

Why use isolated transmitters?
Isolated transmitters protect the electrical instruments by eliminating ground loop effects and reduce substantially the undesirable interferences and instabilities in sensor measurements.

Configurable Input
The TxIsoPack can be configured to accept thermocouples (types J, K, T, E, N, R, S and B), PT100 RTDs, 0-50 mVdc

USB Configuration
The TxIsoPack is configured through a USB port using TxConfig software.
