SML 133 is a basic 3-phase multimeter with large bright
segment LCD display. Instrument is designed for load
or generation monitoring in single-phase and three-phase
low, medium and high voltage networks. Measurement of
actual temperature within a control panel is also supported
with an in-built temperature sensor.
Optional relay or impulse outputs can be programmed to
control other equipment based on measured values (fan
control, over voltage/over current etc). Impulse outputs
can also work as an S0 pulse output for the embedded
electricity meter. Optional communication interface allows
it to be simply configured and managed via ENVIS
application from a remote PC. In combination with ENVIS.
Online service its actual values can be also periodically
downloaded and stored to the SQL database for further
Typical applications: replacement of analog instrument, energy management, sub-metering, remote online
energy and power monitoring, industrial automation.
