Section 1: Introduction Reference Manual 00809-0200-4728, Rev RA April 2015 1.3 Considerations 1.3.1 General Electrical temperature sensors such as RTDs and thermocouples produce low-level signals proportional to their sensed temperature. The 644 converts the low-level sensor signal to a standard 4–20 mA DC or digital HART signal that is relatively insensitive to lead length and electrical noise. This signal is then transmitted to the control room via two wires. 1.3.

PAGE 36
Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 The range of expected readings is defined by the Lower Range Value (LRV) and Upper Range Value (URV). The transmitter range values can be reset as often as necessary to reflect changing process conditions. For a complete listing of Range & Sensor limits, refer to Table A-2 on page 98. Note The re-range functions should not be confused with the trim functions.
PAGE 37
Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 The value chosen for damping affects the response time of the transmitter. When set to zero (disabled), the damping function is off and the transmitter output reacts to changes in input as quickly as the intermittent sensor algorithm allows. Increasing the damping value increases transmitter response time. With damping enabled, if the temperature change is within 0.
PAGE 38
Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 Damping can be applied to a number of parameters in the 644 transmitter. Variables that can be damped are:  Primary Variable (PV)  Sensor 1  Sensor 2  Differential Temperature  Average Temperature  1st Good Temperature Note The instructions below only refer to the damping of the Primary Variable (PV). Damping the transmitter with a Field Communicator From the HOME screen, enter the Fast Key sequence.

Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA 2.8.3 April 2015 Configure alarm and saturation levels In normal operation, the transmitter will drive the output in response to measurements between the lower to upper saturation points. If the temperature goes outside the sensor limits, or if the output would be beyond the saturation points, the output will be limited to the associated saturation point.

Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 2.10 Configure measurement filtering 2.10.1 50/60 Hz filter The 50/60 Hz Filter (also known as Line Voltage Filter or AC Power Filter) function sets the transmitter electronic filter to reject the frequency of the AC power supply in the plant. The 60 Hz or 50 Hz mode can be chosen. The factory default for this setting is 50 Hz.

Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 feature can be switched ON or OFF and the threshold value can be changed to any value between 0 and 100% of the sensor limits with a Field Communicator. When the intermittent sensor detection feature is switched ON, the transmitter can eliminate the output pulse caused by intermittent open sensor conditions. Process temperature changes (T) within the threshold value will be tracked normally by the transmitter’s output.
PAGE 46
Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 2.10.4 Open Sensor Hold Off The Open Sensor Hold Off option, at the normal setting, enables the 644 to be more robust under heavy EMI conditions. This is accomplished by the software having the transmitter perform additional verification of the open sensor status prior to activating the transmitter alarm. If the additional verification shows that the open sensor condition is not valid, the transmitter will not go into alarm.

Reference Manual Section 2: Configuration 00809-0200-4728, Rev RA April 2015 Using the Tri-Loop to detect sensor drift alert The dual-sensor 644 transmitter sets a failure flag (through HART) whenever a sensor failure occurs. If an analog warning is required, the HART Tri-Loop can be configured to produce an analog signal that can be interpreted by the control system as a sensor failure. Use these steps to set up the HART Tri-Loop to transmit sensor failure alerts. 1.

Reference Manual Section 5: Operation and Maintenance 00809-0200-4728, Rev RA 5.3.1 April 2015 Trimming The trim functions should not be confused with the rerange functions. Although the rerange command matches a sensor input to a 4–20 mA output—as in conventional calibration—it does not affect the transmitter’s interpretation of the input. One or more of the trim functions may be used when calibrating. The trim functions are as follows: 5.
