Многофункционален диференциален пресостат с дисплей, обхват 0-60PA, мощност 15-28V DC/AC
- Introduction
DPG Multifunction Digital Differential Pressure Gauge
Applications & Features
l Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure. It can replace most of the traditional pointer mechanical gauges.
l It can measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid level of bubbler systems and pressure amplifier or hydraulic system.
l It can be used in medical care equipment to monitor blood and respiratory pressures.
l Suitable for surface, panel or flush mount
l Multiple ranges and engineering units selectable
l No any movable parts, no any effect on vibration
l The accuracy is up to ±1% FS
l Function keys: zero calibrate, units select, relay set, etc.
l Optional arch LED display for output and alarm

Note: 1. For zero center models, add“Z”at the end of the model. For example, DPG1***Z, means -30-0-30pa. Only ranges 1~6 have this selection.
2. 5 engineering units can be set by the key and then the related LED will be on
