Description

Technical Field

[0001] The utility model belongs to the technical field of pressure transmitters, and particularly relates to a pressure transmitter with an audible and visual alarm device. Background Technique

[0002] A pressure transmitter is a device that converts pressure into an electrical signal for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by a pressure measuring element sensor into a standard electrical signal to supply secondary instruments such as indicating alarm instruments, recorders, and regulators for measurement, indication, and process adjustment. Pressure transmitters are mainly divided into two categories: electric type and pneumatic type. The unified output signal of the electric type is direct current signals such as 0 - 10 mA, 4 - 20 mA, or 1 - 5 V.

[0003] The existing pressure transmitters are usually connected to the required pressure measuring port through a threaded joint, but the threaded joint of the pressure transmitter is usually an integral structure with the pressure transmitter housing. In actual applications, when connecting to pressure measuring ports with different caliber specifications, it is necessary to replace the pressure transmitter with a matching caliber for installation. For example, in the patent document CN204964076U, this reduces the applicable range of the pressure transmitter. Content of the Utility Model
