The SmartLine family pressure transmitters are designed around a high performance piezo-resistive sensor. This one sensor actually integrates multiple sensors linkingprocess pressure measurement with on-board static pressure (DP Models) and temperature compensation measurements. This level of performance allows the ST 700 to replace m ost competitive transmitters available today.

1. Product Range overview:
The SmartLine family pressure transmitters are designed around a high performance piezo-resistive sensor.
This one sensor actually integrates multiple sensors linkingprocess pressure measurement with on-board static pressure (DP Models) and temperature compensation measurements. This level of performance allows the ST 700 to replace m ost competitive transmitters available today.
2. Introduction:
Part of the SmartLine® family of products, the STF700 is suitable for monitoring, control and data acquisition.
STF700 products feature piezoresistive sensor technology combing pressure sensing with on chip temperature compensation capabilities providing high accuracy, stability and performance over a wide range of application pressures and temperatures.
The SmartLine family is also fully tested and compliant with Experion ® PKS providing the highest level of compatibility assurance and integration capabilities.
SmartLine easily meets the most demanding application needs for pressure measurement applications.
3. Features:
* Accuracies up to 0.065 % of calibrated span
* Automatic temperature compensation
* Rangeability up to 100:1
* Response times as fast as 100ms
* Alphanumeric display capabilities
* External zero, span, & configuration capability
* Polarity insensitive electrical connections
* On-board diagnostic capabilities
* Integral Dual Seal design for highest safety basedon ANSI/NFPA 70-202 and ANSI/ISA 12.27.0
* World class overpressure protection
* Full compliance to SIL 2/3 requirements as a standard.
* Modular design characteristics
4. STF700 Model Type:
The ST 700 Flange Mount Pressure Transmitters are ideal for critical applications such as custody transfer of natural gas and energy and material balances, where accuracy and stability are of utmost importance. Here are the transmitters from 400 H2O to 100 psi are available:
STF728 -400 to +400 inH2O -1000 to +1000 mbar
STF732 -100 to +100 psi -7.0 to +7.0 bar
STF72F -400 to +400 inH2O -1000 to +1000 mbar
STF73F -100 to +100 psi -7.0 to +7.0 bar
