Pressure and temperature sensor (TL)#

The Pressure and temperature sensor (TL) block allows you to measure absolute values of pressure and temperature in the nodes of a thermal hydraulic network, or the pressure (temperature) difference between two points of this network.

The absolute sensor has 1 port for connection to the pressure (temperature) control point and measures the absolute value of the parameter in this node.

P=P\(_{in}\), where P\(_{in}\) is the absolute pressure in the node connected to the input port of the unit, [Pa];
T=T\(_{in}\), where T\(_{in}\) is the absolute temperature in the node connected to the input port of the block, [℃].

In the differential sensor, the measured pressures (1) (temperatures (2)) are determined by the points of connection of the sensor to the assemblies of the thermal hydraulic network.

(1)#\[ P=P_{ВХ}-P_{ВЫХ} \]

where:

\(P_{ВХ}\) - pressure in the node connected to the input port, [Pa];

\(P_{OUT}\) - pressure in the node connected to the output port, [Pa].

(2)#\[ T=T_{ВХ}-T_{ВЫХ} \]

where:

\(T_{IN}\) - temperature in the node connected to the input port, [℃];

\(T_{OUT}\) - temperature in the node connected to the output port, [℃].

Note

One sensor can operate in three modes:

Measure pressure only;
Measure temperature only;
Measure pressure and temperature simultaneously.

After adding a sensor to the diagram, use the appropriate sliders to configure it, including the measured parameters.
