Advanced Multifunctional Control

The DPT-Ctrl controller integrates PID algorithms, differential pressure or air flow transmitters, and automated/manual calibration for adaptable and efficient performance. Its industrial-grade microprocessor and ABs plastic housing meet CE and RoHS standards, ensuring safety and compliance for diverse environments.

Flexible Installation and Operation

Wall mount type and dual hose connectors (6 mm & 8 mm) simplify installation, while matte finishing and a compact profile (116 x 81 x 31 mm) suit various settings. The digital LCD display with backlight provides instant readings and easy setup for process optimization.

FAQ's of DPT-Ctrl multifunctional PID controller with differential pressure or air flow transmitter:

Q: How do I install the DPT-Ctrl PID controller for differential pressure or air flow measurement?

A: To install the DPT-Ctrl controller, mount it on a wall using the supplied bracket and screws. Connect the pressure ports with 6 mm or 8 mm hoses to the air or non-aggressive gas source. The electrical connections should be made through screw terminals, following the steps provided in the user manual.

Q: What types of outputs can the DPT-Ctrl PID controller provide for system integration?

A: The DPT-Ctrl offers both relay outputs and analog outputs (0-10 V or 4-20 mA), allowing seamless integration with process control systems, actuators, or building management systems. These outputs can be used for signaling, regulation, or direct process control.

Q: When should I use the calibration feature on the DPT-Ctrl, and how is it performed?

A: Calibration is recommended during initial setup, after maintenance, or periodically to ensure accuracy. The device supports both automatic and manual calibration; instructions are detailed in the user manual, guiding you through either process for reliable measurements.

Q: Where is the DPT-Ctrl PID controller suitable for installation?

A: With its IP65 enclosure rating, the DPT-Ctrl can be installed in industrial settings, clean rooms, laboratories, and areas exposed to dust or moisture-provided ambient temperature remains between -10C and +50C.

Q: What is the response time of the DPT-Ctrl controller, and how does it impact process control?

A: The DPT-Ctrl controller boasts a fast response time of less than one second, ensuring prompt adjustments for critical air pressure and flow control applications. This minimizes lag and enhances overall system stability and safety.

Q: How does programmable alarm output benefit operational safety?

A: The programmable alarm output allows users to set custom thresholds for differential pressure or air flow. When exceeded, the controller triggers an alarm, facilitating immediate corrective action and helping to maintain safe, stable operational conditions.

Q: What communication options are available, and what are their advantages?

A: An optional Modbus RTU interface enables the DPT-Ctrl to communicate with external systems for remote monitoring and control. This feature increases flexibility, supports data logging, and enhances integration in automated environments.
