The pressure transmitter TX3351-GP&AP is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure.TX3351-GP&AP outputs a 4 to 20 mA DC signal corresponding to the measured pressure. The key features include quick response, remote set-up using communications, self-diagnostics and optional status output for pressure high/low alarm.

Span and Range Limits (TX3351- AP) External zero is continuously adjustable with 0.01% incremental resolution of span. Re-range can be done locally using the range setting switch. Rotation in diaphragm plane has no effect. Tilting up to 90 degree will cause zero shift up to 0.25 kPa which can be corrected by the zero adjustment.

The standard setting of failure alarm is High Mode. Response Time The amplifier damping constant is 0.1 sec; The sensor damping constant is 0.1~1.6 sec, it depends on the range and range compression ratio. Amplifier damping time constant is adjustable from 0 to 60 sec by software and added to response time.
