Durable Design for Demanding Applications

Crafted from aluminum die-cast and finished with a high-quality powder coating, the PS 17 provides lasting durability and protection. The IP54 ingress protection ensures the unit can withstand dust and limited moisture, making it ideal for industrial or laboratory use. Its compact form factor supports easy integration into existing systems.


Precise Mechanical Indication

Utilizing a capacitive sensing element and an analog dial, the PS 17 delivers a rapid response time of less than one second. With its 1.5% FS accuracy, users can rely on consistent, direct pressure readings without electrical output, making it suitable where electric signals are unnecessary or prohibited.


Hassle-Free Installation and Operation

The transmitter features a 1/4 BSP female thread connection and is supplied with mounting screws and a user manual, ensuring straightforward setup. The front-adjustable zero knob simplifies calibration, while the large, clear dial allows easy monitoring at a glance.

FAQ's of Draft differential pressure transmitter PS 17:


Q: How is the Draft Differential Pressure Transmitter PS 17 installed?

A: The PS 17 is designed for wall mounting and comes with all necessary mounting screws. It features a 1/4 BSP female thread for pressure connections, enabling simple and secure installation in HVAC, cleanroom, laboratory, or air handling unit environments.

Q: What type of pressure measurement does the PS 17 provide, and how is it displayed?

A: The transmitter measures differential air or non-corrosive gas pressures from 0 to 1000 Pa using a capacitive diaphragm. Readings are displayed on a large 110 mm analog dial, ensuring quick and precise mechanical indication without any electrical output.

Q: When should I adjust the zero point, and how do I perform this adjustment?

A: Zero adjustment is necessary if the pointer does not return to zero when the device is not pressurized. The PS 17 makes this simple with a front-accessible knob, allowing users to quickly recalibrate the dial to maintain accurate measurements.

Q: Where is the PS 17 typically used?

A: This differential pressure transmitter is commonly used in HVAC systems, cleanrooms, laboratories, and air handling units-anywhere precise, reliable low-pressure measurement for clean, non-corrosive gases is required in an industrial setting.

Q: What is the benefit of a mechanical (non-electrical) output in this transmitter?

A: The lack of electrical output eliminates potential interference or risk in electrically sensitive environments and ensures uninterrupted, direct visual monitoring. This design is ideal in applications where only local pressure indication is necessary.

Q: How does the PS 17 maintain durability in industrial environments?

A: Featuring an aluminum die-cast casing with powder coating and an IP54 rating, the PS 17 is resistant to dust ingress and splashed water, prolonging its lifespan in demanding industrial or laboratory environments.
