4-20mA multifunctional digital differential air pressure gauge transmitter with optional arch LED and alarm
DPGT Multifunctional Digital Differential Pressure Transmitter
Applications & Features
- Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure, and supply local display and output simultaneously.
- It can measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels of bubbler systems and pressure amplifier or hydraulic system.
- It can be used in medical care equipment to monitor blood and respiratory pressures.
- Suitable for surface, panel or flush mount
- Multiple ranges, outputs and engineering units selectable
- No any movable parts, no any effect on vibration
- The accuracy is up to ±1%
- Function keys: zero/range calibrate, units select, relay set, output calibrate, etc.
- Optional arch LED display for output and alarm
