Built-in Differential Pressure Transmitter (DPT-300)
|
|
Built-In Housing Type The Accurate Differential Pressure Transmitter (Model : DPT-300) measures the pressure difference by heating the air using dynamic pressure measurement technology.
The DPT-300 adopted the character LCD display(128 x 64 with Backlight) so that the data are easily recognized in the dark.
The DPT-300 offers 1) different pressure measurement & display 2) 4-20mA Current Output, Low / High Alarm function and 3) more easier zero-point calibration to adjust small error easily which can be often occurred during long-term use of this unit.
Also, DPT-300 features the differential pressure calibration for every section, allowing users to easily get more accurate measurement values.

Product Feature
■ DPT-300 adopts Graphic LCD(128 x 64 with Backlight) which allows to recognise pressure in the darkness.
■ DPT-300 adopts 4∼20mA Analog Output as a default, allowing to apply to various transmitters (display).
■ 4∼20mA Analog Output of DPT-300 uses 16Bit DAC, allowing to provide precise analog signals.
■ DPT-300 allows precise control of 4∼20mA Analog Output by setting differential pressure range.
■ In case of deviation in 4∼20mA Analog Output, a built-in digital compensation function allows users to adjust value
by using external keys (current adjustment function).
■ Due to user-focused design, users can configure various parameters easily anytime by using external 5 keys (ESC
(Escape), Enter(Enter), SFT(Shift), UP(Up), DWN(Down)).
■ Built-in alarm offers users a warning (optional).
▼ Alarms can be provided through LCD, LED, Buzzer, and Relay.
▼ Alarm data is displayed through LCD on the left corner as an icon.
▼ When alarm is ringing, the red LED is ON, and the yellow LED is on if ESC key is pressed. In normal operation,
the green LED is ON.
▼ Alarms can be used as Relay Output.
