Product Specs

Omega’s new DPF20 Series of indicators offer real flexibility for measurement of a wide range of frequency or pulse inputs. The display is easily configured to indicate frequency, rate, period or count. This makes the meter ideal for flow applications where they can display flow rate or total from a variety of different flow sensors. Or for quadrature signals, to indicate angular position or rotational speed and direction.

The DPF20 series offers exceptional performance at an economical price, with some unique and powerful features.

Feature

Description

 

Scaling

Multiply, divide and preset values

 

 

Alarms

  1. configure a second setpoint in the same alarm, to create “alarm windows”
  2. configure independent activation and deactivation delays
  3. configure hysteresis
  4. configure alarm to activate as high or low
  5. failsafe function – normally closed relay requires activation for non-alarm condition
  6. latched alarms function – operator reset required
  7. Counter Reset, Stop or Continue
  8. Configurable hysteresis

Power up delay

Allows for a delay in the start-up time after powering the instrument. During this time the instrument performs no measurement or control.
Ability to reset the display count on instrument start-up.

Display Brightness

Select from 5 levels of LED intensity.

Password

Password protect the configuration menu.
This blocks access to the instrument set-up parameters, but the operator can still access set-point values.

Max / min memory

Front panel key selection of display minimum or maximum values

Sensor Type

The fast and simple way to configure a sensor. Select from a predefined list Eg. NPN, PNP, Namur, pick-up, inductive, etc.
The instrument will automatically configure the required parameters for the selected sensor (pull-up / pull-down resistors, trigger level, excitation voltage, etc)

Trigger sense

Simple selection of the optimal trigger level for the sensor input. The display indicates up or down reflecting the status of the input signal level. When the LED changes state continuously the optimal trigger level has been achieved.

I have a DPF20-LV, I was testing the functions and added a password. Now 3 months later I do not recall what that password was, How to I break the pass to get into the unit to see the setting and scaling I used or worst case how do i reset the whole unit.

I am looking to verify that a panel meter such as the Item# DPF20-HV-R1-AO could be used to read/calibrate the output of a rotary encoder such as an AU-ZBG model.

Asked by: InduMar
Thank you for contacting Omega Engineering. Concerning your inquiry, yes the DPF20-HV-R1-AO is compatible with rotary encoders such as an AU-ZBG. It will convert the pulses from the encoder to a speed value, that will be displayed on the screen.
