Digitale Differenzdruckmessung
A digital wall gauge that presents low differential pressure in clear engineering units and adds programmable alarm, relay and communication functions.
- High-Visibility Numeric Display
- Programmable Alarm Limits
- Multiple Pressure Units
- Relay and Analog Outputs
Produkteinführung
The digital differential pressure gauge integrates a low-range sensor, bright numeric display and local alarm logic in one wall-mounted device. Users can select pressure units and view signed room-to-reference differential without converting an analog scale. Programmable high and low limits drive color change, buzzer or relays, while analog and digital outputs share the measured value with monitoring systems. A flush or surface mounting arrangement allows the display to remain readable at entrances and service corridors.
Key Features
Selectable pressure units support Pa and other commonly used engineering scales.
Independent high and low thresholds drive local color and remote relay alarms.
Analog or network retransmission avoids installing a second room pressure sensor.
Kunden Produktbedenken
Room users need an unambiguous pressure value and alarm state without interpreting a small pointer scale.
A small analog scale is difficult to read from the corridor.Large backlit digits present the signed pressure value at a glance.
Staff misinterpret different pressure units used across rooms.A selectable and clearly displayed unit keeps each reading explicit.
The gauge shows pressure but cannot trigger a remote alarm.Programmable relays and analog output send the same condition to the monitoring system.
A brief door opening leaves the display in alarm long after closure.Adjustable delay and hysteresis distinguish transient doorway disturbances from sustained loss.
