5 Precise Input Compensation during operation is achieved with temperature and Pressure correction coefficients that are characterized over the range the Transmitter and stored in the sensor module Transmitter Description EEPROM memory EEPROM stores sensor information and correction coefficients separately from MCU module, allowing Electronics Module for easy repair, reconfiguration and replacement The Electronics module consists of a circuit board sealed in an enclosure. Class 1E safety related Applications There are a MCU module, a power module, Seismic test : IEEE Std 344 at 5 OBE and 1 SSE.

6 An analog module and a terminal module in a Transmitter . response spectrum. The MCU module acquires the digital value from the Environment test : IEEE Std 323 (Thermal, radiation analog module and apply correction coefficients , Functional Aging). selected from EEPROM. EMI/RFI test : MIL-STD-461D & 462D, RG , The output section of the power module converts the IEC61000-4-2(EMC, ESD, EFT/Burst digital signal to a 4~20 mA output. Surge). The MCU module communicates with the HART-based Basic Setup Configurator or Maintenance System such as HTT 275 or ATP3700N Pressure Transmitter can be easily configured 375 and AMS.

7 From any host that support the HART protocol. The Power module have a DC-to-DC Power conversion Operational Parameters. circuit and an Input/output isolation circuit. 4~20mA Points (Zero/Span). An optional LCD module plugs into the MCU module Engineering Units and displays the digital output in user-configured unit. Damping Time : ~ 60 sec Tag : 8 alphanumeric characters Descriptor : 16 characters Sensor Inputs Message : 32 characters. The model APT3700N-D,G,H is available in a Date : day/month/year differential Pressure sensor of a capacitance type.

8 The capacitance Pressure sensor measures differential Calibration and Trimming and gauge Pressure and is commonly used in flow and Lower/Upper Range (zero/span). level applications. Both sides in the capacitance Sensor Zero Trimming sensor transmit process Pressure from Zero Point Adjustment the process isolators to the sensor. DAC Output Trimming The model APT3700N-A,G is available in a absolute Transfer Function Self-Compensation Pressure and high gage Pressure sensor of a piezo- resistive type and measures absolute/high gage Pressure .

9 The sensor module converts the capacitance or the Self-Diagnosis and Others CPU & Analog Module Fault Detection resistance to the digital value. Communication Error The MCU module calculates the process Pressure Fail-mode Handling based on the digital value. LCD Indication Temperature Measurement of Sensor Module Doc. No. : C33700N-E01I.
