产品描述
Omega DPF20系列数字化频率计/计数器/总加器简单易用，使其成为各种流量感应器应用的上佳显示方案。通过这款产品，诸如流速、总和、正交信号和频率都可以准确无误的显示。
作为DP20系列的兄弟产品，其功能强大而且价格实惠。多功能的输出可以自由选择，总有一款适合您。
功能 | 具体描述 |
Scaling | Multiply, divide and preset values |
Alarms | configure a second setpoint in the same alarm, to create “alarm windows” configure independent activation and deactivation delays configure hysteresis configure alarm to activate as high or low failsafe function – normally closed relay requires activation for non-alarm condition latched alarms function – operator reset required Counter Reset, Stop or Continue 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. |
