The SmartLine family pressure transmitters are designed around a high performance piezo-resistive sensor. This one sensor actually integrates multiple sensors linking process pressure measurement with on-board static pressure (DP Models) and temperature compensation measurements
Honeywell STA700 SmartLine Absolute Pressure STA72S-E1G000-1-0-AH0-11S-A-00A0
STA700 is a high performance absolute pressure transmitter with advanced sensor technology.STA700 provides extremely high measurement accuracy and stability over a wide range of static pressures and temperatures by combining absolute pressure with static pressure and temperature compensation on the sensor chip.

●Damping time constant: it can be adjusted within 0~32s and increased to 0.1s.Default value: 0.50s。
To help contain maintenance & inventory costs, all ST 700 transmitters are modular in design supporting the user’s ability to replace meter bodies, standard displays or electronic modules without affecting overall performance. Each meter body is uniquely characterized to provide intolerance performance over a wide range of application variations in temperature and pressure.
• Meter body replacement
• Add or remove standard displays
• Add or remove lightning protection (terminal connection)With no performance effects, Honeywell’s unique modularity results in lower inventory needs and lower overall operating costs.
