The UNICONT series 2-wire passive loop-indicators are universally scalable process value indicators of NIVELCO, operating without the need for power supply. The process indicators find their use where the process value has no control function (such as switching ON/OFF, pressure control, etc.). The 3-wire HART® converter type UNICONT devices offer the optimal solution where local displaying is needed besides the remote data processing and the field transmitters having 4–20mA output are needed to be integrated into HART® multidrop system. The devices are applicable not only for NIVELCO transmitters, but for all transmitters which use standard 4–20mA output.

The UNICONT PDF devices are digital, 2-wire passive / 3-wire active, field process indicators suitable for indication of temperature, pressure, level, etc. values with 6 digit SAP-202 LCD display. Explosion proof versions are available for hazardous environments.

The HART® capable UNICONT PDF 3-wire process indicators require additional power supply. Besides displaying the loop current or the process values, these units convert input current to HART® signals and so enable devices that have analogue outputs only to be integrated into HART® multidrop systems. Robust enclosure makes applications under harsh conditions also possible.
