Goodbye Blind Control: Why AirTAC DPS Series is the "Visual Nerve" of Your Automation System

AirTAC DPS Series Digital Pressure Sensor Header

In modern automation, engineers face an "invisible" cost: unpredictability. While machines represent million-dollar investments, their safety often relies on traditional mechanical pressure switches—essentially "dumb" boxes with aging springs. This leads to Setpoint Drift and the dreaded Contact Chatter, which flickers signals and burns out solenoid valve coils.

In an era demanding 100% predictability, you need a "Visual Nerve" that can see, think, and report stably. This is where the AirTAC DPS Series Electronic Digital Pressure Sensor transforms the "blind" guessing game into "What You See Is What You Get" precision.

1. Immediate Diagnosis: The Power of Visual Feedback

Dual Row LCD Display

Dual-Row Display: The Setup Revolution

Traditional sensors force engineers to toggle between "Run Mode" and "Setup Mode." The AirTAC DPS solves this with a Dual-Row LCD. You can see the current pressure (top row) while simultaneously setting the switch point (bottom row). This real-time feedback reduces setup time from minutes to seconds and eliminates manual setting errors.

Dual-Color Display: At-a-Glance Diagnosis

The DPS screen doesn't just show numbers—it changes color. Program the sensor to display Green during normal operation and switch to Red when the setpoint is reached or a fault occurs. In a noisy factory floor, a glaring red light instantly draws maintenance attention, drastically reducing the Mean Time To Repair (MTTR).

2. Deep Control: Designing Your Application Response

Control Logic Functionality

Control Mode I: Hysteresis (The Chatter Killer)

The DPS eliminates signal flickering with Programmable Hysteresis. By setting an ON point (e.g., 500 kPa) and a Hysteresis Value (e.g., 20 kPa), you create a "Dead Zone" that absorbs normal pressure fluctuations, ensuring the PLC receives a clean, stable output signal.

Control Mode II: Window Comparator (The Safety Guard)

Using its independent transistor outputs, the DPS can guard a "Safety Working Zone." If the pressure is too low (leak) or too high (regulator failure), the sensor alerts the PLC immediately. This is invaluable for critical applications like precision press-fitting or leak testing.

Filtering Fluctuations:

The DPS offers an adjustable response time from 2ms to 5000ms. By adjusting this setting, you can tell the sensor to ignore transient pressure spikes caused by valve shifting, preventing false alarms and simplifying your PLC logic.

3. OEM Strategy: Global Deployment & Assembly

Global Versatility Features
  • Unit Versatility: Built-in support for kPa, bar, psi, and mmHg. One part number covers all global export requirements.
  • Parameter Copy Function: Set the Master sensor once, then link it to Slave sensors via a cable. Perfect settings are replicated in seconds, transforming hours of high-risk manual setup into a zero-error automated process.
  • High Precision: Maintains a repeatability of ±0.2%F.S. for the entire life of the machine, ensuring consistent quality.

4. Integration: NPN vs. PNP Selection

Electrical Integration
DPSP1 (PNP / Sourcing):

The "Positive" switch. Provides a +24VDC signal to the PLC. This is the standard for European and North American systems (Siemens, Allen-Bradley) where the PLC input COM connects to 0V (GND).

DPSN1 (NPN / Sinking):

The "Negative" switch. Sinks current to 0V (GND). This is the standard for Asian automation systems (Mitsubishi, Omron) where the PLC input COM connects to +24VDC.

Frequently Asked Questions

Q: My air pressure fluctuates wildly. How can I stop false alarms?

A: Use the Adjustable Output Delay to ignore sharp spikes that last less than a set duration (e.g., 500ms), and combine it with Hysteresis to stabilize the switch point.

Q: Can the DPS handle vacuum applications?

A: Yes. The AirTAC DVS Series is specifically designed for vacuum sensing, utilizing the same dual-display technology as the DPS series.

Automation's Visual Nerve

The AirTAC DPS Series is not just a sensor; it is a diagnostic tool that eliminates failure modes at the source. By moving from "blind" mechanical switches to intelligent digital control, you gain the stability and data required for modern Industry 4.0 production lines. Build with speed, deploy with certainty.
