DPG/PS Filter Guard

Application: DPG/PS filter guards provide a solution for systems requiring on-site visual indication of pressure and a switching point signal. They are particularly suitable for general-purpose work in air-conditioning and ventilation systems, especially in air filter monitoring applications.

Features:

  • Combination of Differential Pressure Switch and Gauge: Integrates both a differential pressure switch and gauge into a single practical product, offering convenience and efficiency in monitoring pressure conditions.
  • Multiple Pressure Ranges: Available in several pressure ranges to suit different application requirements, including DPG200/PS200, DPG300/PS300, DPG500/PS500, DPG600/PS600, and DPG1.5K/PS1500.
  • High Accuracy: Offers a typical switching point accuracy of ±8 Pa at the low limit and ±15% at the high limit for most models, ensuring reliable performance in pressure detection.
  • Wide Gauge Range: Provides gauge ranges from 0 to 200 Pa up to 0 to 1500 Pa, catering to various pressure monitoring needs.
  • Switching Difference: Each model features a specific switching difference, such as 20 Pa, 30 Pa, or 80 Pa, depending on the pressure range, ensuring precise control and signaling.
  • Long Product Lifetime: Designed to withstand over 1,000,000 switching operations, ensuring durability and longevity in operation.
  • Pressure Connections: Equipped with Ø5 mm pressure connections for easy installation and connection to the system.
  • Output: Utilizes a change-over contact output, capable of handling loads of 250 Vac, 3 A (resistive) and 2 A (inductive), ensuring compatibility with various systems.
  • Operating Conditions: Designed to operate in temperatures ranging from -5 to 60 °C and humidity levels of 0 to 95% RH (non-condensing), suitable for diverse environmental conditions.
  • Weatherproof Design: Features a robust construction with ABS and PC plastic parts, silicone membrane, PVC hose, and steel bracket, offering protection against harsh conditions.
  • IP54 Protection: Provides IP54 protection class, ensuring resistance to dust and water ingress, suitable for outdoor and indoor installations.
  • Easy Mounting: Facilitates installation with two Ø5.5 mm screw holes and one slotted hole for flexible mounting options.
