What’s the dissipation loss for a pressure transmitter?

Highly Effective ?dissipation loss? can be found in the info sheet for a pressure sensor or pressure transmitter. One needs this specification in order to be 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 sufficient reason for this, in the worst case, a total failure of the instrument. So how can the right electrical connection be managed?
Important of the correct electrical connection on the basis of the dissipation loss
First, the utmost permissible electrical energy for the pressure sensor must be known. This is given in the info sheet because 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 the actual maximum electrical energy for the pressure sensor that occurs can be determined. Impatience 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 energy for the pressure transmitter (PPressure transmitter), that is now known, should be smaller than 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 will withstand the mandatory operating temperatures.
