Abstract

The invention discloses a stress transmitter which comprises a detection tube, a control device, a position limiting device, and a spring sheet contact type voltage sensor. The detection tube is horizontally arranged with two openings at two ends. The position limiting device is fixedly clamped onto the external part of the detection tube. The position limiting device, through a bearing, is connected in a rotation manner at one end of the bearing shaft. The other end of the bearing shaft is fixedly connected to the control device which comprises a control module, a power supply module, a display screen, and an adjusting button. The display screen, the adjusting button and the control module are connected through conductive wires. The spring sheet contact type voltage sensor is fixedly arranged in the detection tube and is connected to the control device through conductive wires. The voltage signals detected by the spring sheet contact type voltage sensor are transmitted to the control module through conductive wires, and are displayed on the display screen for people to conveniently check. With the adjusting button, currently available detection data can be stored; and previous detection concerned data that are stored can also be conveniently accessed. With a bearing, the entire control device can be rotated so as to facilitate the process of data check by a user according to their specific requirements.

Description

technical field [0001] The invention relates to a pressure transmitter, in particular to a shrapnel contact type pressure transmitter. Background technique [0002] A pressure transmitter refers to a pressure sensor whose output is a standard signal. It is an instrument that accepts pressure variables and converts them into standard output signals in proportion. It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal (such as 4-20mADC, etc.), to supply secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement and indication and process regulation. When the pressure directly acts on the surface of the measuring diaphragm, the diaphragm produces a small deformation, and the high-precision circuit on the measuring diaphragm transforms this small deformation into a highly linear ratio proportional to the pressure and proportional to the excitation voltage. Voltage s...
