摘要： A compact pressure differential/pressure detector is a process detection apparatus for measuring a pressure, a level, a pressure differential of a process fluid. The detector is constructed of a pressure sensing block having sensors for sensing a pressure and a pressure differential, a signal processing block for processing signals from the pressure sensing block, and a terminal board block for receiving power supply from outside and transmitting signals to outside. These blocks are arranged along the same axis. Furthermore, an indicator indicating a process state is also arranged along the same axis and received in a covering case. The case is firmly attached to the pressure sensing block. The process detection apparatus permits a compact design and offers an excellent maintainability.

摘要： A differential pressure transmitter for detecting a difference between a pressure of a first detection fluid in a first pressure-receiving chamber and a pressure of a second detection fluid in a second pressure-receiving chamber, including a first diaphragm for sealing the first detection fluid, a second diaphragm for sealing the second detection fluid which is installed almost in parallel to the first diaphragm, a first isolation chamber communicated to the first pressure-receiving chamber, a second isolation chamber communicated to the second pressure-receiving chamber, a third diaphragm installed between the first and the second chambers and in a direction different from those of the first and second diaphragms, and a differential pressure detection sensor installed on and connected to at least one of the first and the second isolation chambers. The differential pressure transmitter having a symmetrical construction has a high sensitivity because difference between transmitting coefficients in pressure transmitting paths in high and low pressures is minimized.

摘要： A differential pressure transmitter detects a differential pressure condition of a fluid by means of a semiconductor sensor. First and second seal diaphragms are provided in a member which constitutes the differential pressure transmitter, to form first and second pressure receiving chambers. An overload protection diaphragm and first and second damper chambers are provided at positions close to the first and second pressure receiving chambers. Also, there are provided a passage for connecting the first pressure receiving chamber and the first damper chamber, a passage for connecting the second pressure receiving chamber and the second damper chamber, and passages for connecting the first and second damper chambers respectively with the semiconductor sensor. Even when a change is caused in the temperature of a processed fluid to be detected, the differential pressure transmitter quickly detects the temperature change, so that a differential pressure of the processed fluid can be measured with high accuracy.
