The user can choose according to the actual needs of different types of STT250 transmitter:? STT25H with HART communication capabilities for HART communication protocol, and can be any tool to configure HART communication with HART 6 STT25S communications and TUV SIL2 certification? ? STT25M applicable to 4-20mA communications, available Field Communicator (SFC), the intelligent configuration tool (SCT) or MCT multi-protocol communications in the field or control room configuration? STT25D with DE communications, both for 4- 20mA communications, can also be connected to TDC3000 / TPS / Experion PKS control system for digital integration? STT25T can access two sensing port signal pressure transmitter offer for all models Mutual sensors or sensor redundancy are more wire system, using the same temperature sensor, and provides a process temperature into an output signal linear relationship, while the heat resistance wire compensation to provide diffused silicon pressure transmitter, thermocouple provides internal digital cold junction compensation. Furthermore absolute pressure transmitter, millivolt and ohm input signal can be used as the transmitter. Smart Transmitter: smart transmitter is composed of sensors and a microprocessor (computer) from the phase structure. It takes full advantage of the computing and storage capacity microprocessor, sensor data can be processed, including the measurement signal conditioning (such as filtering, amplification, A / D conversion, etc.), data display, automatic calibration and automatic compensation. The microprocessor is the heart of the smart transmitter. It can not only measurement data computing, storage and data processing, but also through a feedback loop to adjust the sensor so that the collected data to achieve the best. Since the microprocessor has a variety of software and hardware functions, so that it can complete the traditional transmitters difficult task. So Smart transmitter reduces the difficulty of making the sensor and improve the performance of the sensor in the largely lord. In addition, the smart transmitter also has the following characteristics: 1, with automatic compensation capability, nonlinear, temperature drift, when the drift of the sensor and so automatically compensated by software; 2, self-diagnosis, after power to the sensor self-test to check the various parts of the sensor is normal, and make judgments; 3, easy and accurate data processing, automatic data processing in accordance with internal procedures, such as statistical processing, removing abnormal value; 4, with two-way communication. The microprocessor can not only receive and process sensor data, but also the information back to the sensor, thereby measuring process regulation and control; 5, information storage and memory, can store the sensor characteristic data, configuration information, and compensation characteristics ; 6, the interface with digital output, the output of the digital signal can be easily and computer or field bus connection.
