RSA-TDP Differential Pressure Transmitter

Applications & Features

• Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure
• 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 of 1.0% and range as low as 25Pa
• Function keys: zero calibrate, unit select, response time set, etc
• Field upgradable LCD display module and multiple ranges selection

Models

Measuring Rangers

1. Code 1 and 3 have multiple ranges which could be jumper selected.
2. Set the 5 engineering units by button keys and the related LCD indicator will be on.
3. For zero center models, add “Z” at the end of the model. For example, RSA-TDP1**Z, means the range is-30-0-30/-62.5-0-62.5pa. Only ranges 1~6 have this selection.
