RSA-TDPH High Accuracy Differential Pressure Transmitter
Applications & Features
- Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure, and air velocity or volume
- It can measure system pressure of fan, blower, filter, furnace draft and orifice plate and can apply to various clean room, biological safety cabinet, clean bench, ducts collection, medical or pharmaceutical machine, etc.
- Multiple ranges, engineering units and outputs
- Good performance with accuracy up to 0.5% and range as low as 25Pa
- Function keys: zero reset, unit select, response time set, square root output set (air velocity or volume), K factor calibrate and area parameter’s input, etc.
- Field upgradable LCD display module
- Square root output: when applying along with pitot tubes or other air velocity or volume sensor, can supply linear output for air velocity or volume

Models
Measuring Ranges
- Set the 5 engineering units by button keys and the related LCD indicator will be on.
- For zero center models, add “Z” at the end of the model. For example, RSA-TDPH1**Z, means the range is -30-0-30/-62.5-0-62.5pa. Only ranges 1~6 have this selection.
