Pressure Transmitter Smart SN

Relative pressure transmitter

The compact Honeywell Smart SN pressure transmitter provides an economic solution for a wide range of applications. The Smart SN series is suitable for measuring the relative pressure of fluids and gases. Recorded pressure values between –1 and +1 bar and between 0 and 40 bar are converted to a 4–20-mA or 0–10-V signal.

Optionally, the transmitter is available with a dual backlit LCD display which can be swiveled and rotated in 90-degree steps by software.
