differential pressure transmitter 4-20mA with high accuracy differential pressure sensor
Applications & Features
- Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative ordifferential pressure
- It can measure fan and blower pressures, filterresistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels of bubbler systems and pressure amplifier or hydraulic system, and in medical care equipment to monitorbloodand respiratory pressure
- Multiple ranges, engineering units and outputs
- Very high performance/price ratio, 1% or 2% accuracy
- Function keys: zero calibrate, unit select, response time set, etc
- Field upgradable LCD display module

Note: 1. the code 1and 3 have two or three measuring ranges, selected by jumper
2. Set the 5 engineering units by button and related LCD indicator will be on
3. For zero center models, add “Z” at the end of the model. For example, DPT1**Z, means full range 60 or 125pa, but actual output is -30-0-30pa or -62.5-0-62.5pa respectively
