Differential pressure gauge for HVAC applications

The DPG series differential pressure gauges are engineered for HVAC/R applications. The DPG series devices measure air and non-corrosive gas pressures (differential and positive) and provide a clear analog display of the measured values. The DPG series devices include field adjustable zero point calibration and overpressure protection.

DPG series devices are commonly used in HVAC/R systems for:

• Fan, blower and filter monitoring
• Pressure and flow monitoring
• Pressure monitoring in cleanrooms

Measuring units:

• Pa Measurement ranges: 0–60 Pa
• 0–100 Pa
• 0–120 Pa
• 0–200 Pa
• 0–250 Pa
• 0–300 Pa
• 0–400 Pa
• 0–500 Pa
• 0–600 Pa
• 0–800 Pa
• 0–1 kPa
• 0–1,5 kPa
• 0–2 kPa
• 0–3 kPa
• 0–5 kPa

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.

Applications:

The filter alerts are a solution for systems requiring visual indication 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.

BECK Digital Differential Pressure Gauge 990
General Description:
The differential pressure gauges 990 Display are for air andnon-aggressive gases and will be used to measure differential pressure, overpressure and vacuum. They offer one adjustablepressure range and two output signals, which can be selectedin the menu. The type 990M has a manual zero offset calibration,the type 990A has an automatic zero offset calibration.


Adjustable pressure range:
To adapt the instrument to the application, the factory-set pres-sure range can be modified in the menu in a range from 100% to 20% of its full scale value.

Switchable pressure units:
The instrument offers three different pressure units to show in thedisplay, which can be selected in the menu. Factory setting isPascal, which can be changed to mbar or inWC.

Switchable output signal:
The output signal is either 0...10V or 4...20mA, which can beeasily changed in the menu.

Adjustable response time:
The response time of the output signal can be configured usingthe menu in a range from 0.1 to 20s.

Easy offset calibration:
The output signal of the type 990M can be re-calibrated to zeroin the menu when the instrument is in a pressure less state. The series 990A performs an automated zero offset compensation.Here any drift of the zero-point is automatically corrected in regular intervals. No re-calibration is needed which reducesmonitoring and maintenance efforts.

Volume flow measurement:
The shape of the output signal can be changed in the menufrom linear to square rooted to enable a volume flow measurement via a differential pressure reading.

Switching output:
To give a switch signal at an user defined pressure level theinstrument has two adjustable relay switching outputs witha maximum switching capacity of 250VAC/5A
