The term ?dissipation loss? are available in the info sheet for a pressure sensor or pressure transmitter. One needs this specification in order to be in a position to protect the pressure sensor from overheating.
In Funny is operated in a hot environment, it really is necessary to limit its electrical power. If one neglects this aspect, one possibly risks an overheating sufficient reason for this, in the worst case, a complete failure of the instrument. So how can the correct electrical connection be managed?
Determination of the correct electrical connection on the basis of the dissipation loss
First, the maximum permissible electrical power for the pressure sensor should be known. This is given in the info sheet as the dissipation loss. Please be aware that the dissipation loss could be dependent upon the utmost expected operating temperature of the instrument and should be calculated where necessary.
If the allowable dissipation loss has been determined correctly, then your actual maximum electrical power for the pressure sensor that occurs can be determined. The determination can be executed expediently in two steps:
1. Determination of the voltage at the pressure transmitter utilizing the following formula:
UPressure transmitter = UVoltage source ? RLoad � Imax. Current supply
2. Calculation of the maximum electrical energy for the pressure transmitter through the next equation:
PPressure transmitter = UPressure transmitter � Imax. Current supply
The maximum electrical energy for the pressure transmitter (PPressure transmitter), that is now known, must be smaller compared to the permissible dissipation loss. If this is the case, both the power (UVoltage source) and the strain (RLoad) were properly calculated and the electrical energy of the pressure sensor will be within the permissible range under all operating conditions. Consequently, the pressure transmitter will not heat too strongly and can withstand the required operating temperatures.
