The term ?dissipation loss? are available 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 is usually 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. So how can the right electrical connection be managed?
Determination of the right electrical connection based on the dissipation loss
First, the utmost permissible electrical energy for the pressure sensor must be known. That 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 should be calculated where necessary.
If the allowable dissipation loss has been determined correctly, then your actual maximum electrical power for the pressure sensor occurring can be determined. Embarrassing 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 utmost electrical power 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, should be smaller than the permissible dissipation loss. If this is actually 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, Spine will not heat too strongly and will withstand the required operating temperatures.
