Device Description
The ProSense DPM3 series offers a simple, feature packed digital display of analog process
signals, temperature in either Fahrenheit or Celsius from RTD or Thermocouple temperature
sensors, load cell, or potentiometer inputs. The 5-digit tri-color red, green or amber LED
display is easily scaled into any engineering units from -19999 to 39999 with a selectable
decimal point location. Two point direct or reverse acting linear scaling values can be entered
manually or by introducing actual sensed process values in Teach mode. Additionally non-
linear processes can be scaled by entering up to 11 scaling points. Models are available with
two SPDT or four SPST relay outputs that can be set to activate on an increasing or decreasing
input signal with hysteresis or time delay operation. Additionally the display color can be set
to change on relay operation. Models are also available with a 4-20mA analog output. The
meter is powered from an external AC or DC power supply and provides both 24VDC and
10VDC for external sensor excitation. The 1/8 DIN housing is easy to install in a panel and
the meter face has an IP65 rating. Configuration parameters can be totally or selectively
locked out to prevent unauthorized or accidental changes to the meter’s operation. Other
features include memory and reset of minimum and maximum display values, three tare
functions, display hold function, filtering to minimize display bounce, and display brightness
adjustment. ProSense digital panel meters are backed by a 3 year warranty.
