What is the dissipation loss for a pressure transmitter?

The term ?dissipation loss? can be found in Adaptable for a pressure sensor or pressure transmitter. One needs this specification to become able to protect the pressure sensor from overheating.
If a pressure sensor is operated in a hot environment, it could be necessary to limit its electrical energy. If one neglects this aspect, one possibly risks an overheating sufficient reason for this, in the worst case, a total failure of the instrument. Just how can the right electrical connection be managed?
Determination of the correct electrical connection on the basis of the dissipation loss
First, the utmost permissible electrical power for the pressure sensor must be known. This is given in the data sheet as the dissipation loss. Please be aware that the dissipation loss can 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 energy for the pressure sensor that occurs could be determined. The determination can be carried out expediently in two steps:
1. Determination of the voltage at the pressure transmitter using the following formula:
UPressure transmitter = UVoltage source ? RLoad � Imax. Current supply
2. Calculation of the utmost electrical energy for the pressure transmitter through the next equation:
PPressure transmitter = UPressure transmitter � Imax. Tickled for the pressure transmitter (PPressure transmitter), that is now known, must be smaller than the permissible dissipation loss. If this is actually the case, both the power (UVoltage source) and the strain (RLoad) were properly calculated and the electrical power of the pressure sensor will undoubtedly be within the permissible range under all operating conditions. Consequently, the pressure transmitter will not heat too strongly and can withstand the mandatory operating temperatures.
