DPG/PS Filter alert

Product catalog summary

Model Summary
The document provides an overview of the DPG/PS series, which combines differential pressure gauges and switches into a single product. These are designed for filter monitoring, offering both alarm signals and local display capabilities. The models range from DPG200/PS200 to DPG1,5K/PS1500, with varying measurement ranges from 0–200 Pa to 0–1500 Pa.

Applications
The DPG/PS series is suitable for systems requiring visual pressure indication and a switching point signal, particularly in air-conditioning and ventilation systems for monitoring air filter contamination.

Specifications

Performance: Accuracy of gauge is ±2% at 20 °C. Switching differences range from 20 Pa to 80 Pa depending on the model.
Electrical Rating: Resistive load is 3 A / 250 VAC, with inductive load at 2 A / 250 VAC.
Maximum Pressure: 50 kPa.
Service Life: Over 1,000,000 switching operations.

Technical Specifications

Media Compatibility: Suitable for dry air or non-aggressive gases.
Operating Environment: Temperature range from -5 to +60 °C, storage from -40 to +85 °C.
Physical Attributes: Case and duct connectors made of ABS, cover of PC, and membrane of silicone.
Protection Standard: IP54.

Conformance
The product meets CE marking requirements, including RoHS, LVD, and WEEE directives. The company is certified by DNV GL for ISO 9001 and ISO 14001 standards.

USER-FRIENDLY MEASURING DEVICES filter alerts dpg/ps series Combination of a differential pressure gauge and a differential pressure switch In many situations filter monitoring requires an alarm signal and a local display. Our filter alerts are the right solution for these situations. The DPG/PS filter alerts combine differential pressure switches with gauges into one practical product offering. • DPI series electronic differential pressure switches The filter alerts are a solution for systems requiring visual indi cation of pressure on site and a switching point signal. The filter alerts are ideal for general-purpose work in air-conditioning and ventilation, especially in monitoring of air filters for contamination.
