[0003] However, although in practical applications, the measuring range of the selected pressure transmitter is 1.5 times the actual maximum pressure, the existing pressure transmitter in the actual work of the load cell sensor, due to the actual industrial operating environment , There will be pressure spikes or continuous pulses: For example, at the moment of sudden start, stop, speed change or reversing of the hydraulic system, due to the inertia of the flowing liquid and moving parts, a high peak pressure is instantaneously formed in the system, making the fluid directly and continuously impact The load cell sensor is easy to cause damage to the load cell sensor, resulting in a low service life of the pressure transmitter

The invention relates to the field of pressure transmitters, and discloses a pressure transmitter suitable for high-intensity impact, including a transmitter detection tube body, including a transmitter detection tube body, and the bottom of the transmitter detection tube body is fixed A flange is connected, and the middle part of the transmitter detection pipe body is provided with a main fluid channel in a vertical direction. The pressure transmitter suitable for high-intensity impact, through opening grooves on both sides of the main fluid channel in the transmitter detection tube, using the damping block design method that moves laterally in the through groove, under normal working conditions, the gas or The liquid flows through the fluid channel. The groove at the damping block in the main fluid channel acts on the diaphragm of the load cell sensor. The damping effect is realized through the structure of the damping block, which prevents the load cell sensor from being subjected to continuous high-pressure pulses of the fluid, which may easily cause pressure measurement. The problem of damage to the element sensor improves the service life of the transmitter.
Description
technical field [0001] The invention relates to the field of pressure transmitters, in particular to a pressure transmitter suitable for high-intensity impacts. Background technique [0002] A pressure transmitter is an instrument that converts a pressure variable into a transmissible standardized output signal. It converts the pressure into an activation signal or an electric signal for control and remote transmission. It can convert the gas sensed by the load cell sensor Physical pressure parameters such as liquids and liquids are converted into standard electrical signals for secondary instruments such as indicating alarms, recorders, and regulators to measure, indicate, and process adjust. It is the most commonly used sensor in the industry and is widely used in industrial automation. Power engineering, oil well and many other industries. [0003] However, although in practical applications, the measuring range of the selected pressure transmitter is 1.5 times the actua...
