Beck

Beck pressure transmitters are available in a variety of measurement ranges to suit different combustion and HVAC applications. Common ranges include 0–0.5/0–1 mbar, 0–1/0–2.5 mbar, 0–2.5/0–5 mbar, 0–5/0–10 mbar, 0–10/0–25 mbar, 0–25 mbar, 0–50/0–100 mbar, and 0–100 mbar. These ranges cover low differential pressures typical of burner air flow monitoring as well as higher pressures for gas or duct applications. Each transmitter model is factory-calibrated to its specified range, and some models offer dual-range capability (e.g., 0–5/0–10 mbar) for flexibility. When selecting a transmitter, verify the required pressure range and the system's operating conditions to ensure accurate measurement.

Certain Beck pressure transmitter models are rated to IP65, which provides protection against dust ingress and low-pressure water jets from any direction. This makes them suitable for installation in environments where moisture or dust may be present, such as outdoor burner enclosures or washdown areas. For example, the Beck Pressure Transmitter 0-2.5/0-5 Mbar IP65 (model 985M333204b) is explicitly rated to IP65. For applications with more severe exposure, verify the specific model's IP rating and consider additional protective enclosures if needed. Always check the datasheet for the exact ingress protection level before installation.

Beck pressure transmitters feature digital readout capability, allowing for on-site verification of the measured pressure and system status. This digital display enables maintenance personnel to quickly confirm that the transmitter is functioning correctly and that the pressure reading matches the expected value. This is particularly useful during commissioning, troubleshooting, or routine calibration checks. The digital readout eliminates the need for external test equipment in many cases, reducing downtime and simplifying field diagnostics. For models without a display, a multimeter can be used to check the analog output signal.

Beck offers a range of mounting accessories to facilitate installation on various burner and ductwork configurations. These include L-shaped and S-shaped metal brackets, which allow for flexible positioning of the pressure switch or transmitter on flat or angled surfaces. Climaset assemblies are also available, which include PVC hose configurations for connecting the pressure sensing lines to the device. Additionally, bent metal tube variants are offered for applications requiring rigid tubing connections. These accessories are designed to simplify installation, reduce vibration effects, and ensure proper orientation of the sensing ports. Selecting the appropriate bracket or assembly depends on the mounting location and the available space.

Yes, Beck pressure switches are commonly used for fan proving in burner management systems. These switches detect the differential pressure created by the combustion air fan, confirming that adequate airflow is present before the burner is allowed to ignite. The switches are available with set-points in the range of 0.2 to 3 mbar, which covers typical fan proving requirements. They are designed to operate reliably within tight tolerances, ensuring that the safety interlock functions correctly. When selecting a pressure switch for fan proving, consider the required set-point, the switching differential, and the electrical rating to match the burner control system.

A Beck pressure switch provides a discrete on/off output when the pressure crosses a set-point, making it suitable for safety interlocks and alarm functions. In contrast, a Beck pressure transmitter provides a continuous analog signal (typically 4-20 mA or 0-10 V) proportional to the measured pressure, allowing for modulating control or continuous monitoring. Pressure switches are used in applications like fan proving or high/low gas pressure cut-off, while transmitters are used for precise pressure measurement in combustion control loops or for data logging. The choice depends on whether you need a simple switching action or a variable signal for process control.
