FIELD: physics, measurement.
SUBSTANCE: invention refers to measurement equipment and is intended to provide pressure difference measurement. Pressure-difference transmitter contains a case with two partitioned cavities, spring, and sensor fixed between cavities. Partition has two valves to supply pressure to cavities through jets, which flow passage is smaller than that of valves. Jets are designed so that to limit rate of pressure rise within corresponding cavities. Springs are fixed in valves so that the latter can operate in safety valve mode.
EFFECT: elimination of measurement errors.
