DIFFERENTIAL PRESSURE SWITCHES PS Series

Product catalog summary

Model Summary
The document provides a summary of the PS series differential pressure switches, detailing models, product codes, and measurement ranges. The models range from PS200 to PS4500, with measurement capabilities from 20 Pa to 4500 Pa.

Product Description
The PS series mechanical differential pressure switches are designed for air applications in HVAC/R systems. They offer a cost-effective solution for monitoring filters, fans, and ducts, with adjustable switching points and measurement units in Pascals (Pa).

Similar Products
Other related products include the DPI series electronic differential pressure switches and the DPT-R8 series 8-range differential pressure transmitters.

Applications
These devices are used for fan, blower, and filter monitoring, as well as pressure and flow monitoring, and valve and damper monitoring in HVAC/R systems.

Specifications

Performance: Accuracy varies by model, with typical low limit accuracy of ±5 Pa for lower range models and up to ±100 Pa for the PS4500. High limit accuracy ranges from ±20 Pa to ±200 Pa. Switching differentials range from 20 Pa to 250 Pa.
Overpressure: Proof pressure is 25 kPa, and burst pressure is 50 kPa.
Technical Specifications: Compatible with dry air or non-aggressive gases, operating temperature from -20 to 60 °C, and storage temperature from -20 to 85 °C. The protection standard is IP54.
Physical: Dimensions are 105 x 73 x 63 mm, with a weight of 150 g. The case is made of ABS, and the cover is PC.
Electrical: Input ranges from 24–250 VAC, with NO/NC circuit output. Electrical ratings vary by model.
Conformance: Meets CE marking requirements, including RoHS, LVD, and WEEE directives.
