1． Feature Description
△ DF9032Dual-channel thermal expansion monitor, accepts one or twoLVDTInput signals from the sensor system continuously measure and monitor the thermal expansion of the machine housing or the valve position and stroke, providing protection for the mechanical equipment.
△ DF9032Dual-channel thermal expansion monitor, based onDSPIntelligent meter for processors.
Parameter settings are throughDF2900Configuration software completed.
Normal observation operations can be completed through the instrument panel keyboard.
The following features are standardly provided:
▲ Instrument functions can be programmed to:
Two independent channels: each channel is measured separately; the two channels do not interfere with each other.
Two channels monitor the same parameter: Measuring the same parameter with two channels enables high-reliability measurement, and
Features include differential identification;
Two-channel compensation measurement: One channel measures positive displacement, and the other measures negative displacement.
Measure the full displacement of the channel assembly.
Inclination Measurement: Measures inclination displacement and automatically compensates for slope, converting to thermal expansion.
▲ The direction of displacement measurement, compensation for inclined surface measurement, and compensation for connection to the safety barrier are all programmable, with automatic compensation calculation during measurement.
▲ The instrument supplies each sensor with a DC power supply featuring overvoltage protection and short-circuit protection.
▲ The buffered sensor input signal is provided through the terminal on the back panel (optional).
▲ Warning of monitoring values, danger over-limit discrimination, and status indication, output;
▲ Each channel provides programmable output voltage or current signals to recorders and similar devices.
▲ The alarm control output logic of the instrument is programmable:
"OR" logical operator──Any channel exceeding the time limit triggers the relay to activate.
"AND logic"──Both channels triggered relay operation upon exceeding the time limit.
▲ The four control relays of the gauge are programmable, allowing for the option to select interlocking or not, and each relay can be configured as a single (or dual) channel as needed.OKOne of the functions including warning, positive warning, negative warning, danger, positive danger, and negative danger; (This feature is not provided at present)
▲ Instrument parameters and data are stored inE2PROMIndoor, can be stored long-term in case of power failure.
△ DF9032Dual-channel thermal expansion monitor with comprehensive self-check and self-diagnostic functions:
▲ The processor performs self-checks on the instrument measurement loops at regular intervals, assessing the operational status of each channel's measurement loop.
In the event of a fault in the loop, automatically bypass it to disconnect it from operation.
▲ A line for monitoring the operation and integrity of each sensor and its cable.OK Circuit)，at a certain
Sensor coil open (open circuit) or short circuit, or abnormal output from the preamplifier, etc., occur, the system will automatically activate:
The hazard control output of this channel has failed, causing protective relays to malfunction and resulting in incorrect shutdown of the equipment.
▲ At power supply input165～265VacThe widthWithin the range, the entire instrument operates with high reliability and stability.
Operation.
The instrument monitors the power supply, and can automatically respond to power outages, power-ons, and abnormal fluctuations.
Set the circuit to locked operating status, bypass the hazardous relay output, and wait for power to return to normal before resetting the relay to the maintained state.
Continued operation.
△ DF9032Two-channel thermal expansion monitor, in addition to the standard functions mentioned above, especially provides the following:
Features, the following features are specifically designed for high-reliability monitoring:
▲ Sensor Linear Compensation:
ThroughDF2900Configuration software, capable of inputting from the keyboard or automatically collecting up to 20 sensor segments
According to the table,Gauges linearly correct sensor data according to this data table.
Users can choose whether to apply linear correction to the sensor.
▲ Difference Identification:
For more reliable monitoring, when both channels monitor the same displacement amount, the difference between them exceeds the limit value.
It's highly probable that there's a fault with the sensor or the measuring circuit; when the differential exceeds the limit, the user can choose whether to...
Issue warnings and lockout hazardous outputs to prevent unintended operation, providing the crew with enhanced reliability and protection.
▲ Rate of Change Discrimination
Thermal expansion or valve position and stroke volume are typically slow variables. When abrupt changes occur, it is usually due to sensors
Equipment or measurement circuit failure is not due to actual changes in the thermal expansion values of the unit. When the rate of change exceeds
Limited time offer: Users can choose to issue warnings and lock out dangerous control outputs to prevent accidental operations.
Group offers more reliable protection.
