What is the dissipation loss for a pressure transmitter?

pressure gauge 10 bar ?dissipation loss? can be found in the data sheet for a pressure sensor or pressure transmitter. One needs this specification to become in a position to protect the pressure sensor from overheating.
If a pressure sensor is operated in a hot environment, it really is essential 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. So how can the right electrical connection be managed?
Determination of the correct electrical connection on the basis of the dissipation loss
First, the maximum permissible electrical energy 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 can be dependent upon the maximum expected operating temperature of the instrument and must be calculated where necessary.
If the allowable dissipation loss has been determined correctly, then the actual maximum electrical energy for the pressure sensor occurring could be determined. The determination can be carried out 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 utmost electrical power for the pressure transmitter through the next equation:
PPressure transmitter = UPressure transmitter � Imax. เพรสเชอร์เกจ for the pressure transmitter (PPressure transmitter), which is now known, must be smaller than the permissible dissipation loss. If this is the case, both the power (UVoltage source) and the load (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 will withstand the mandatory operating temperatures.
