What’s the dissipation loss for a pressure transmitter?

The term ?dissipation loss? can be found in the data sheet 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 really is essential to limit its electrical energy. If one neglects this aspect, one possibly risks an overheating and with this, in the worst case, a total failure of the instrument. Just how can Left Behind be managed?
Determination of the correct electrical connection on the basis of the dissipation loss
First, the utmost permissible electrical energy for the pressure sensor should be known. That is given in the info sheet because the dissipation loss. Please note 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 the actual maximum electrical power 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 using 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 power for the pressure transmitter (PPressure transmitter), which is now known, must be smaller than the permissible dissipation loss. If Blissful is actually the case, both the power supply (UVoltage source) and the strain (RLoad) were properly calculated and the electrical energy 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 required operating temperatures.
