The DP18 Series offers a modular
design for easy selection and
installation of options and inputs.
Field-installable signal conditioner
cards provide the large user or OEM
the ability to stock options and
spare signal conditioner cards for
converting input types, meter
functions or repair. For customers
who need flexibility and wish to add
options to the meter as
requirements become more
demanding, the DP18’s fieldinstallable analog outputs, relays
and communications offer an
economical solution.
The DP18 series is a complete
family of panel meters with input
cards for voltage, process and
temperature measurement and
control. The voltage signal
conditioners will measure AC or DC
voltages or true RMS. Signal
conditioners for process inputs
accept low-level voltage or current
which can be scaled for engineering
units. Temperature meters will
provide accurate measurement of
thermocouples or RTD’s. Other
inputs include differential process,
load cells or potentiometers.
Combined with OMEGAs wide
selection of transducers, the DP18
Series is the single solution for
process measurement.
