Versatile Pressure Range for Enhanced Applications

Spanning a pressure range of 20 to 300 Pa, Series 104-0 is optimized for measuring low differential pressures in air and non-corrosive gases. Its practical range and robust design make it an ideal choice for HVAC monitoring, filter condition detection, and fan performance analysis in both commercial and industrial settings.

Quick and Accurate Adjustment

The external adjustment knob allows users to swiftly set the required switching point without opening the housing or disrupting the installation. The device maintains excellent accuracy at 2% of full scale, ensuring operational reliability and reducing maintenance downtime.

Durable Construction and Protection

This switch is encased in a polycarbonate housing with metal internal parts, providing strength while protecting sensitive components. Its IP54 rating, splash-proof cover, and silicone rubber seals ensure resilience against dust and moisture, making Series 104-0 suitable for challenging environments with a long service lifespan.

FAQs of Sensocon USA Differential Pressure Switch Series 104 - 0 Pressure Range 20-300 Pa:

Q: How do I adjust the set point on the Sensocon Series 104-0 Differential Pressure Switch?

A: The set point can be conveniently adjusted using the external knob provided on the housing. This allows for precise setting of the switching pressure without needing to open the cover or disconnect the switch from its installation.

Q: What are the main benefits of using this differential pressure switch in HVAC or industrial systems?

A: The Series 104-0 ensures efficient monitoring and control of air or non-corrosive gas pressure, enabling timely maintenance alerts and helping maintain optimal system performance. Its quick response time (<1 second) and 2% accuracy further bolster reliable operation.

Q: Where should the Sensocon Series 104-0 be installed for best performance?

A: For standard use, the switch should be mounted vertically on a wall or panel with the provided screws. Ensure the pressure connections are made using a 6 mm OD tube, and place the device in environments within the specified operating temperature range of -10C to +60C.

Q: What is the typical process for wiring and connecting this pressure switch?

A: Connect the switchs SPDT contacts as per the included instruction manual, using wires suitable for a 250V AC, 5A load. The pressure sensing ports are compatible with 6 mm OD tubing or 1/8 NPT female threads to link with your pressure source.

Q: When is it necessary to replace or recalibrate this pressure switch?

A: Routine system checks are recommended, but the switchs fixed hysteresis and external adjustment mechanism generally offer maintenance-free operation for extended periods. Replace or recalibrate the device only if you notice persistent deviation from the set pressure or after prolonged service in challenging conditions.

Q: What gases can be measured with the Sensocon Series 104-0?

A: This switch is engineered to measure the differential pressure of air and non-corrosive gases only. It should not be used with aggressive or corrosive gases that may damage the internal components or seals.

Q: How does the IP54 protection rating benefit the installation?

A: The IP54 rating means the device is protected against limited dust ingress and water splashes from any direction, extending its service life and ensuring safe operation, even in environments where moisture or dust is present.
