Description
The Pressure block & Temperature Sensor (TL) It is an ideal sensor that measures pressure and temperature in a heat-conducting liquid network. There is no mass and energy flow through the sensor.
The sensor contains an implicit reference node, which means that only the A port is needed to measure absolute pressure and temperature, as well as overpressure.
The B port is used if you need to measure the pressure or temperature difference between two nodes in the model. The measurements are positive when the pressure and temperature values in port A are greater than the values in port B.
Four signal ports are available for outputting measurement data:
-
Pa is the absolute pressure.
-
Pg — excessive pressure.
-
P is the pressure difference.
-
T is the temperature (temperature difference).
These ports are displayed on the block icon depending on the block settings. Configure the block parameters so that only those ports that are necessary for measurements in a particular model are displayed.
Ports
Non-directional
A — pass sensor input:q[<br>] heat-conducting liquid
The port of the heat-conducting liquid corresponds to the entrance to the sensor.
B — pass sensor output:q[<br>] heat-conducting liquid
The port of the heat-conducting liquid corresponds to the sensor output. The measurements are positive when the pressure and temperature values in port A are greater than the values in port B.
Dependencies
To use this port, set the Measurement reference parameter to Difference.
Output
Pa — absolute pressure, Pa
scalar
The output port. Displays the result of the absolute pressure measurement.
Dependencies
To use this port, set the Measurement reference parameter to Absolute, select the Pressure checkbox and set the Pressure type parameter to Absolute pressure.
Pg — overpressure, Pa
scalar
The output port. Displays the result of the overpressure measurement.
Dependencies
To use this port, set the Measurement reference parameter to Absolute, select the Pressure checkbox and set the Pressure type parameter to Gauge pressure.
P — pressure difference, Pa
scalar
The output port. Outputs the result of measuring the pressure difference.
Dependencies
To use this port, set the Measurement reference parameter to Difference and select the Pressure checkbox.
T — temperature, K
scalar
The output port. Displays the result of temperature measurement if the value of the Measurement reference parameter is set Absolute — the absolute temperature is measured if Difference — the temperature difference in ports A and B is measured.
Dependencies
To use this port, select the Temperature checkbox.
Parameters
Measurement reference — measurement of absolute values or the difference of
Absolute (by default) | Difference
Sets the method for measuring pressure and temperature:
-
Absolute― The sensor measures the absolute or excess pressure and temperature in port A. The sensor contains an implicit reference node, which means that only the A port is needed for pressure or temperature measurements. -
Difference― The sensor measures the pressure and temperature difference between two nodes in the model. When this option is selected, the B port is displayed on the block icon.
Pressure — enabling or disabling the output port for pressure measurement
enabled (by default) | turned off
When this option is selected, the output port Pa, Pg or P is activated, allowing pressure measurement.
Pressure type — type of measured pressure
Absolute pressure (by default) | Gauge pressure
Choose which pressure the sensor measures — absolute or excessive:
-
Absolute pressure― The sensor measures the absolute pressure in port A. When this option is selected, the Pa port is displayed on the block icon. -
Gauge pressure― The sensor measures the overpressure in port A. When this option is selected, the Pg port is displayed on the block icon.
Dependencies
To use this parameter, set the Measurement reference parameter to Absolute and select the Pressure checkbox.
Temperature — enabling or disabling the output port for measuring temperature (temperature difference)
disabled (by default)
When this option is selected, the output port T is enabled, which allows temperature measurement (temperature difference).
