"The DP18 series is a complete family of panel meters with input cards for voltage, process and temperature measurement and control. The signal conditioners for voltage will measure ac or dc voltages or true RMS." - https://www.omega.co.uk/
Economical Digital Meters DP18 - Omega
Modular Design, Options for Alarms, Analog Output of Communications, 3 1/2-Digit LED Available in Red or Green Displays
Other inputs include differential process, load cells or potentiometers. Combined with OMEGA’s wide selection of transducers, the DP18 series is the single solution for process measurement.
In Response to Email from JPE - US WV to delabs
"I would like to know if you offer a monitoring solution that will constantly measure ambient (air) temperature (say, 0 to 150°F), and provide a corresponding DC voltage output of either 100 mV, 1 V, 5 V, or 10 V. Do you make a unit that can be configured to do this?"
