The USD-2 is a smart, PC programmable, galvanically isolated two-wire transmitter. The unit converts 13 types of thermocouple sensors, 12 types of RTD sensors, potentiometer, resistor and millivolt inputs, into process current loop.
The USD-2 is unique with its integral 3 ½ digits LED display.
24 bit A/D converter and two microprocessors are the heart of the outstanding performance. The USD-2 samples and updates the output current in a rate of 2 - 3 samples per second depends on the sensor type.
The transmitter is fully configurable in Dry-Configuration ™ mode by which the communication to PC is performed with no external power source.
Internal Pt-100 temperature sensor provides precise cold-junction compensation throughout the entire ambient range. Detection of sensor breakage or disconnection of input leads, forces the output to a pre-defined up/down scale value.
The unit continuously monitors the sensor and automatically returns to normal operation mode when the sensor is recovered.
The USD-2 is housed in a standard DIN rail enclosure.
